A method to determine kinetic triplet by coupled with model-free method and model-fitting method
Abstract: The present study is aimed to obtain integral linear method using rational expressions given by Senum and Yang, and a method of selecting the reaction model more quickly and easily and compute the activation energy and pre- exponential factor more accurately was proposed. An improved linear integral procedure coupled with one model-free method and one model-fitting method for the determination of kinetic triplet using non-isothermal data recorded at several heating …

Biohydrogen Production via Thermochemical and Biological Routes
Abstract: Hydrogen is a crucial energy vector for developing a sustainable bioeconomy and can be produced from renewable biomass sources. This review explores various biological and thermochemical pathways for biomass-to-hydrogen conversion. Thermochemical processes include pyrolysis, gasification, fast pyrolysis, steam reforming, and supercritical water gasification, while biological approaches encompass photofermentation, dark fermentation, mixed fermentation, and bio- photolysis. Despite its potential, achieving reliable and selective hydrogen production is essential for economically viable industrial …

Transforming Carbon: The Science and Potential of Gasification
Abstract: Methanol and chemicals like urea and ammonia, which are the building blocks of many fertilizers, can be produced via the gasification process. Additionally, gasification can assist in the production of transportation fuels from biomass, coal, oil, and sands. Drying, pyrolysis, combustion, cracking, and reduction are the five distinct thermal processes that make up gasification. Drying removes moisture from the feedstock, while pyrolysis breaks down complex hydrocarbons into simpler molecules. Combustion …

Perovskite Oxides: A Multifunctional Material Class for Solar-to-Fuel Energy Conversion
Abstract: Harnessing concentrated solar energy for thermochemical water and carbon dioxide splitting presents a promising pathway to produce liquid hydrocarbon fuels as a sustainable alternative to fossil fuels. This process relies on advanced redox materials to facilitate efficient chemical reactions within thermochemical cycles. Traditionally, research has focused on binary oxides, particularly ceria, due to its redox capabilities. However, ceria’s high reduction temperature and limited tunability via extrinsic doping hinder its optimization …

Advancing Clean Energy: The Role of Biohydrogen Technology
Abstract: The process of gasification turns carbonaceous materials derived from biomass or fossil fuels into gases, with nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2) being the main fractions. By reacting carbonaceous materials (coal, petroleum, and biomass) with a regulated amount of oxygen and/or steam at high temperatures, a thermochemical process known as gasification produces carbon monoxide and hydrogen. Methanol and chemicals like urea and ammonia, which are …
