Publication Energía solar térmica en Cuenca: Un modelo innovador para la transición energética en Ecuador(Universidad de Cuenca, 2024-12) Montero Izquierdo, Iván Andrés ; Valdivieso, Evelin; Encalada, RosanaPublication Design and development of a catalytic fixed-bed reactor for gasification of banana biomass in hydrogen production(2022) Tacuri Sarmiento, Diego Mauricio; Andrade Herrera, Christian Javier; Álvarez Lloret, Edgar Paúl; Abril González, Mónica Fernanda; Salamea Piedra, Teresita Silvana; Pinos Vélez, Verónica Patricia; Jara Cobos, Lourdes Elizabeth; Montero Izquierdo, Iván AndrésHydrogen produced from biomass is an alternative energy source to fossil fuels. In this study, hydrogen production by gasification of the banana plant is proposed. A fixed-bed catalytic reactor was designed considering fluidization conditions and a height/diameter ratio of 3/1. Experimentation was carried out under the following conditions: 368 °C, atmospheric pressure, 11.75 g of residual mass of the banana (pseudo-stem), an average particle diameter of 1.84 mm, and superheated water vapor as a gasifying agent. Gasification reactions were performed using a catalyzed and uncatalyzed medium to compare the effectiveness of each case. The catalyst was Ni/Al2O3, synthesized by coprecipitation. The gas mixture produced from the reaction was continuously condensed to form a two-phase liquid–gas system. The synthesis gas was passed through a silica gel filter and analyzed online by gas chromatography. To conclude, the results of this study show production of 178 mg of synthesis gas for every 1 g of biomass and the selectivity of hydrogen to be 51.8 mol% when a Ni 2.5% w/w catalyst was used. The amount of CO2 was halved, and CO was reduced from 3.87% to 0% in molar percentage. Lastly, a simulation of the distribution of temperatures inside the furnace was developed; the modeled behavior is in agreement with experimental observations.Publication Biodiesel Production by Transesterification of Recycled Oil Catalyzed with Zinc Oxide Prepared Starting from Used Batteries(2023) Seminario Calle, Doménica Paulina; Álvarez Lloret, Edgar Paúl; Duque Sarango, Paola Jackeline; Cisneros Ramos, Juan Fernando; Pinos Vélez, Verónica Patricia; Ortega Maldonado, Melissa Isabel; Echeverria Paredes, Paulina Alejandra; Montero Izquierdo, Iván AndrésThe consumption of batteries and cooking oil have been increasing. Most used batteries are disposed of incorrectly, leading to health and environmental problems because of their composition. In a similar form, cooking oil, once used, is often released by the discharge reaching the wastewater, polluting soil, and water, which affects its treatment. In Ecuador, these environmental passives are recollected and stored without further treatment, which is a temporary and unsustainable solution. To address this issue, the circular economy concept has gained increasing attention. In this study, zinc oxide was prepared from discarded batteries using the hydrometallurgical method to use as a catalyst; it achieved 98.49% purity and 56.20% yield and 20.92% of particles presented a particle size of 1–10 nm. Furthermore, the catalyst morphology was investigated in an SEM, which showed that particle size ranged from 155.69 up to 490.15 nm and spherical shapes. Due to its characteristics, the obtained catalyst can be used in the industry instead of the zinc oxide obtained by mining processes. These processes are known to produce heavy contamination in the ecosystems and human health. Additionally, a zinc oxide lifecycle in the environment was analyzed through a material flow analysis (MFA), taking into consideration two paths, one assuming the disposal of used batteries and the other assuming the recycling of zinc. Biodiesel was produced with a heterogeneous catalyst. This took place with a transesterification reaction with used cooking oil, ethanol, and zinc oxide (ZnO) as catalysts. The biodiesel obtained had the following characteristics: 37.55 kJg−1 of heating power, 0.892 gcm−3 of density, 4.189 mm2/s of viscosity, 0.001% of water content, and a 70.91% yield. Furthermore, the energy consumption in biodiesel production was quantified, giving a total of 37.15 kWh. This kind of initiative prevents that waste from becoming environmental pollutants and potential health risks by giving them a second use as a resource. Moreover, turning waste into a valuable product makes the processes self-sustaining and attractive to be implemented.Publication Design and implementation of a web-based residential energy assessment platform: a case study in Cuenca-Ecuador(Springer Nature, 2021) Carrión Chamba, Willian Oswaldo; Acosta Pazmiño, Iván Patricio; Montero Izquierdo, Iván Andrés; Valdivieso Garcia, Katy Viviana; Naranjo Ulloa, Christian Naranjo; Murillo Torres, Wilson Adrian; Montero Izquierdo, Iván Andrés ; Carrion Chamba, Willian OswaldoPopulation confinement caused by the COVID-19 pandemic has led to an increase in household energy consumption. Electricity consumption in the residential sector in Latin America and the Caribbean increased by 20% during 2020 in comparison to 2019. An upsurge in electricity consumption at the residential level was observed between March and August of 2020 due to the emergency sanitary declaration in Ecuador. Viewed in this context, the residential customers of Cuenca have increased their consumption by around 13% during May 2020 in comparison to the same month of the previous year. Adopting energy efficiency and sufficiency measures could counteract this increase in energy and contribute to managing the demand in the residential sector. The present work aims to evaluate energy savings and emissions reduction in the residential sector in Cuenca through the design and implementation of a web-based platform for estimating electricity power savings. To develop the platform, information was gathered, through surveys, on the energy consumption of the average household. Power consumption of appliances was obtained from various sources, mainly from a database provided by a local appliance retailer. Energy-saving strategies for electrical and electronic appliances were taken from technical guidelines and academic sources. The functional and visual specifications of the platform were designed with specialized tools. The platform allows for calculating household electrical energy consumption and potential savings in energy, economic, and environmental terms in a simple and visually attractive manner. The study shows that 4 members of a family household consumes an average of 182 kWh/month, which is equivalent to 17.1 USD and an annual environmental footprint of 1068.9 kg of CO2. From this energy consumption, 57% is consumed by household appliances, 31% corresponds to technology and entertainment, and 12% represents lighting. Nevertheless, it is possible to reduce monthly energy consumption by 45% if energy sufficiency and efficiency measures are applied by consumers. This reduction will produce a monthly saving of 7.9 USD and an annual reduction of 485 kg of emissions. By implementing this web-based tool non-specialized users can analyze and decide the best way to reduce energy consumption, creating an appropriate energy culture with a positive impact on the household economy and promoting environmental sustainability.Publication La energía solar térmica y su aplicabilidad en la industria: una alternativa viable para descarbonixar el sector(Red Ecuatoriana de Innovación y Educación Superior - CEDIA, 2025-11-17) Montero Izquierdo, Iván AndrésPublication A review of the state-of-the-art of solar thermal collectors applied in the industry(2022) Carrión Chamba, Willian Oswaldo; Murillo Torres, Wilson Adrian; Montero Izquierdo, Iván AndrésThe energy consumption associated with the industry sector represents 38% of the global energy demand, being an important aspect that marks the development of a country. In this sense, it is extremely important to diversify the different energy sources and incorporate the use of renewable energy sources, such as solar energy, not only with the idea of ensuring energy supply, but also as elements that enable the reduction of energy emissions generated by the use of fossil fuels. This work addresses the main solar collector technologies that may be incorporated into different types of industries, based on experiences and research in other countries. Based on this review, it has been seen that an important part of the industries worldwide requires temperatures up to 250 °C in their processes, which makes suitable the use of solar energy technology. Depending on each industry, flat plate, vacuum tube, Fresnel type or parabolic trough solar collectors may be used. Finally, the savings associated with some facilities are detailed and the challenges related to this sector are addressed.
