A Comparative Thermodynamic and Kinetic Analysis of Methane Tri-Reforming for Syngas Production: A Process Simulation Approach
type: item
description: The growing concentration of greenhouse gases, primarily methane (CH₄) and carbon dioxide (CO₂), underscores the need for advanced carbon capture and utilization (CCU) technologies. Methane tri-reforming (TRM) has emerged as a highly promising pathway for the valorizitation of these gases, converting them into syngas (a mixture of H₂/CO), which serves a critical feedstock for the chemical industry. This study develops and applies a comprehensive process simulation framework to systematically evaluate the TRM process, addressing a notable gap in the literature regarding the rigorous comparison between thermodynamic limits and actual kinetic performance under different feed compositions. Using the DWSIM process simulator (version 8.1.2), a comparative analysis was conducted employing two distinct reactor models: a Gibbs reactor model to determine thermodynamic equilibrium limits and a kinetic Plug Flow Reactor (PFR) model to assess performance under practical conditions. The investigation evaluated three different feed compositions, varying the molar ratios, with the objective of identifying optimality criteria based on: (1) maximum combined conversion of CH₄ and CO₂, (2) suppression of coke formation, (3) efficient production of adjustable syngas, and (4) favorable energy balance. The thermodynamic analysis identified an optimal operating window between 800 K and 900 K at atmospheric pressure, where reactant conversions are maximized and secondary coke-forming reactions are suppressed. The kinetic analysis revealed that an ideal feed composition (molar fractions of: CH₄= 0,545, CO₂ =0,182, H₂O =0,091) achieves a methane conversion of 33,0% and produces syngas with an H₂/CO molar ratio of 3,0 at 800 K, representing the best compromise between conversion and selectivity. Finally, thermal and composition profiles along the reactor were evaluated, demonstrating syngas formation and the accelerated methane consumption during the tri-reforming process. This work provides a…

Configuration of the Coffee Production Chain in Norte de Santander
type: item
description: The research analyzes the structural and relational configuration of the coffee production chain in Norte de Santander, aiming to identifying the links and the degree of correlation among the actors involved, from production to commercialization in national and international markets. To achieve this, a thread diagram was designed to illustrate the product´s transition through each link-actor, characterizing geographical distribution, actor density, input–output flows, and loss points within the system. The statistical analysis revealed a positive correlation between resistant varieties and modern agricultural practices with crop yield, while traditional and susceptible crops showed lower performance over large áreas. This diagnosis made it possible to identify deficiencies in organization, transportation, and grain handling, which have caused losses exceeding 30% over the last decade, particularly affecting small and medium-sized producers; it is concluded that strengthening cooperatives, renewing traditional crops, and adopting modern agricultural practices are key strategies to reduce losses, increase productivity, and consolidate the competitiveness of Norte de Santander´s coffee in both national and international markets.

Analysis of the decrease in diclofenac concentration in aqueous solutionusing ozone intensified by hydrodynamic cavitation
type: item
description: A hydrodynamic cavitation system was analyzed to intensify the ozonation of diclofenac present in aqueous solution. An ozone generator with a capacity of 5 g de O3/h was used. Hydrodynamic cavitation was induced through a Venturi tube connected to the outlet of a 745,7 W pump with a discharge pressure of 0,41 MPa. The flow rate driven by the pump was 0,0005 m3/s, and the system was operated in complete recirculation. A central composite experimental design was used to determine the effect of the initial pH of the solution (4 and 7) and the initial diclofenac concentration (5 mg/L y 10 mg/L). The experimental results were evaluated using analysis of variance, determined that the experimental variables and their interactions up to the second order affect the response variable, corresponding to the percentage of diclofenac removal. The response surface methodology allowed identifying the conditions to achieve the highest removal percentage, reaching 40% with an initial pH of 4 and a diclofenac concentration of 5 mg/L. In all test, the cavitation number was 0,797, which confirms the formation of cavities within the liquid. The reaction time in each of the experiments was 0,5 h. The effectiveness of the process under these conditions is mainly attributed to the fact that diclofenac remains in its non-ionized form, whose hydrophobicity favors its accumulation at the interface of the cavities formed in the Venturi throat, where it is attacked by the OH radicals generated during collapse. Furthermore, the intensifying effect of hydrodynamic cavitation on ozonation can be attributed to the improvement in the mass transfer of ozone into the water due to turbulence in the Venturi throat, as well as by the ozone decomposition that generates OH radicals in the medium.

Bioconversion of potato peels using black soldier fly larvae (Hermetia illucens)
type: item
description: In the present study, the effect of larval density (0, 1, 2, and 3 larvae/cm²) on the bioconversion of potato and reduction of potato peels (Solanum tuberosum) was evaluated using black soldier fly larvae (Hermetia illucens). The hatching of the eggs produced a total of 72,512 larvae per gram. The final bioconversion showed values ranging from 16.8% to 27.8%, while waste reduction ranged from 59% to 77%. The highest values for both indicators were recorded in treatments with 3 larvae/cm2. Although increasing larval density reduces the size of each individual, the presence of more larvae per unit area improves both bioconversion and waste reduction. The use of this technology allows the transformation of potato peels into organic compost and larval biomass rich in proteins and fats, which could be used for animal feed, thereby contributing to the valorization of this agro-industrial waste.

Sizing a photovoltaic solar installation to meet the electricity demand of a middle-income residential home in the city of Bogotá
type: item
description: The research analyzes the economic feasibility of implementing a photovoltaic solar panel system in a middle- class household in Bogotá. To this end, detailed information was collected on the home's energy consumption, the area’s solar irradiation conditions, and the appropriate system components were selected. A comprehensive economic analysis was carried out, considering the initial investment, payback period, and projected profits over 25 years. The technical calculations were performed using the "worst month" methodology, identifying the period in which it is most difficult to meet energy demand with solar energy. This methodology confirmed that, through the installation of four panels connected to the electrical grid, t is possible to meet the household’s energy demand. The results showed that the system would generate significant savings in electricity consumption and reduce CO₂ emissions by approximately 118 kg per year. The initial investment (COP $ 5.725.087) would be recovered in 4,7 years, reaching a projected profit of COP $ 225.015.860 over 25 years. These findings demonstrate that the implementation of the system is not only profitable but also environmentally sustainable, establishing itself an effective alternative to reduce costs and mitigate environmental impacts in urban residential sectors.

type: item
description: Air Quality in Bogotá, particularly in the locality of Fontibón, represents a public health issue due to the high concentration of fine particulate matter (PM2.5). This study employs a descriptive model to analyze pollution patterns along Calle 13, where peaks in concentration were identified during. the early morning hours. The analysis was based on data collected from fixed air quality monitoring stations located in the area over a 12-month period. This information made it possible to identify seasonal patterns and evaluate the influence of factors such as vehicular traffic and meteorological conditions. T For the processing and analysis of public data provided by the District Secretariat of Environment of Bogotá, the OpenAir library in the R programming language was used, applied to the locality of Fontibón. Through this tool, variables such as wind direction, critical locations, and the effect of the vehicle fleets were evaluated in comparison with the various industrial emission sources present in the area. The results indicate that PM2.5 levels exceed the limits recommended by the World Health Organization (WHO), especially during peak hours between 5:30 a.m. and 8:00 a.m., and between 5:00 p.m. and 7:00 p.m. Likewise, it was found that the months with the highest PM2.5 concentrations in 2024 were August, October, and November, with average increases of 8% compared to the other months. Finally, it is concluded that air quality in this area represents a significant health risk for residents, highlighting the need to implement public policies aimed at improving urban air quality and controlling pollutant emissions.

Evaluation of co-digestion of pig manure, poultry manure, banana peel and chicken manure (poultry manure with rice husk) for biogas production
type: item
description: Biogas is a renewable energy source generated from the anaerobic analysis of organic matter, where mainly carbon dioxide and methane are produced, the latter used for the generation of electrical and thermal energy. In this study, three prototypes of sealed biodigesters were evaluated with different organic substrates: pig manure, poultry manure, chicken manure, banana peel and water. These prototypes were designed to allow the release of gases while maintaining an anaerobic environment to generate biogas production. The production of methane, hydrogen, liquefied petroleum gas (LPG), carbon monoxide, propane and ethanol were measured, using daily sensors. The results showed that the biodigester containing banana peel biomass, water and pig manure generated higher gas content measured in the physicochemical properties, during a period of 6 weeks in which the measurements were made. In conclusion, biogas stands out as a clean and sustainable alternative to fossil fuels in the generation of electricity and heating. The study also seeks to evaluate the co-digestion of pig manure, poultry manure and chicken manure to identify the optimal combination of substrates that maximizes biogas production.

EICHHORNIA CRASSIPES: FIBER EXTRACTION
type: item
description: This paper presents an experimental alternative for fiber extraction from the stem of Eichhornia crassipes. This plant, belonging to the Pontederiaceae family, is one of the invasive aquatic species in tropical and subtropical regions of the world. Fiber extraction begins with the collection of the plants directly from the aquatic mass, followed by dissection of its parts and individual extraction of each of these. The fibers obtained maintain their structural integrity despite the abrasive nature of the methods employed. Obtaining a standard fiber from Eichhornia Crassipes is influenced by several factors, including the purity of the extracted material and the intrinsic quality of the stem, which play a crucial role in the uniformity and properties of the fibers obtained. Eichhornia Crassipes has the potential to become a valuable and sustainable resource for fiber extraction by offering environmental benefits.

Analysis of the effect of a Hydraulic Work on the Water Quality of the Teusacá River (Cundinamarca, Colombia) through Bioindication with Aquatic Macroinvertebrates
type: item
description: The main objective of this research is to analyze the effect caused by a hydraulic dredging intervention in the Teusacá River (Cundinamarca, Colombia), by means of bioindication of aquatic macroinvertebrates. Dissolved oxygen, turbidity, temperature and pH measurements were taken at each sampling point, and various water quality indices (BMWP/Col, ASTP, IBF, EPT), as well as biodiversity indices (Shannon Weaver, Simpson, Margalef and Menhinick) were calculated. Four sampling points were taken in the months of June, October, and December, collecting a total of 1160 organisms grouped into 6 classes, 13 orders and 19 taxonomic families, these organisms were used for the comparative assessment of water quality before and after the Hydraulic work. For the analysis of the effect of the hydraulic work on water quality, one sampling point was considered as a post-intervention reference, and previous research in the same area was considered as references prior to the work. The dredging had a slightly positive effect on the river's water quality, evidencing improvements in the physicochemical parameters and quality indexes, which reflect an increase in its quality.

Vegetation analysis from spectral indices and its relevance in the identification of water mirrors in the Torca Guaymaral wetland, Bogotá, Colombia
type: item
description: In Colombia, several wetlands have experienced significant changes in the water mirror, either by natural or anthropogenic processes; most of these wetlands show eutrophication, a fact that is evidenced by the uncontrolled proliferation of algae, herbaceous and sedges, making them vulnerable to phenomena such as global warming. This study focuses on the Torca - Guaymaral wetland located in the extreme north of the city of Bogotá (Colombia), which is currently affected by the rapid spread of hydromorphic vegetation. This aquatic ecosystem is habitat for countless species, while at the same time providing multiple benefits to society as an urban wetland. The analysis of the study area was performed based on vegetation and humidity in comparison with the data yielded by the NDVI and NDWI indices in the years 2014 and 2023 in the months of January and February, respectively. The wetland maps are made using ArcGIS software to process Landsat 8-9 satellite images, with a cloud cover range below 60 % and downloaded from the USGS EarthExplorer platform. The results indicate the decrease of wetlands in the Torca-Guaymaral by 7.3 %, while the scarcity of vegetation increased by 12 %, it was observed that dense vegetation decreased by 3 % and moderate vegetation by 9.24 %.

Preparation of a Moisturizing Drink Based on Milk Whey and Strawberry Pulp
type: item
description: The goal of this project is to create a protein-rich beverage based on whey and various amounts of pulp from the Fragaria fruit (strawberry). The whey was physicochemically characterized, and three beverage formulations with varied percentages of strawberry pulp (10, 25, and 40% w/w) were created. The hydrating beverages obtained were tested for pH, acidity in lactic acid and consumer sensory acceptability. The three formulations meet the physical and chemical standards described in NTE INEN 2609:2012 for whey beverages, and statistical analysis reveals no statistically significant changes between treatments. An untrained panel carried out the sensory evaluation where the main organoleptic characteristics were taken into account. The 60% whey and 40% strawberry beverage received the most approval, while taste was the highest ranking element.
