Internal dry reforming of methane in solid oxide fuel cells

Chemical Engineering Journal, Journal Year: 2024, Volume and Issue: 489, P. 151281 - 151281

Published: April 15, 2024

In the context of global efforts to reduce greenhouse gas emissions and combat extreme warming, direct dry reforming methane reaction in solid oxide fuel cells presents a promising avenue for clean energy production. This study delves into influence temperature, composition, current density on kinetics cells. Power Law Langmuir-Hinshelwood kinetic models were proposed highlight impact operating conditions reactions. Results revealed that feed composition strongly affects conversion, with higher contents resulting lower conversions. Increasing CH4/CO2 ratio increases rates, effect decreases at 1.25. The changes concentration rate are more significant than those carbon dioxide. However, increasing dioxide enhances conversion. exothermic nature CO2 adsorption suggests process is thermodynamically favourable reforming, elevated temperatures generally improve rates conversion by removing deposits providing needed break down chemical bonds which facilitating its transformation. A significantly equilibrium constant further highlighting positive role electrochemical reactions reforming. aims fill knowledge gap regarding behaviours cells, offering critical insights advancing anode design, thus contributing development cell technologies address warming emissions.

A novel integrated gas-cooled fast nuclear reactor and vanadium chloride thermochemical cycle for sustainable fuel production

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 468, P. 142853 - 142853

Published: June 12, 2024

The continuous growth of anthropogenic carbon emissions from the aviation industry has emphasized urgent request to substitute traditional fuels with Sustainable Aviation Fuels (SAFs) because SAFs can potentially reduce by around 50-90% as compared kerosene-based fuels. In this paper, a novel SAF production pathway been developed which is based on biomass processing, nuclear energy, and thermochemical reactions vanadium chloride cycle for SAF, clean power, hydrogen production. entire system assessed thermodynamically in terms energy exergy performances. Various sensitivity analyses are computed determine reliable operating parameters. study concludes that biomass-to-SAF energetic exergetic performance was achieved be approximately 76.72% 74.35%. values, through efficiencies, V-Cl were calculated 68.08% 53.50%, respectively. For storage, an penalty 16.83 kJ/kg H2 calculated, results efficiency 6.18%. overall efficiencies proposed integrated found 59.79% 23.78%,
