The article discusses the growing interest in hydrogen generation through various reforming processes like steam, dry, and autothermal reforming. It highlights the research on heterogeneous catalysts sourced from renewable assets such as methanol, ethanol, and glycerol for hydrogen synthesis. The study emphasizes the use of specific catalyst supports like mesoporous structure SiO2 and alumina, which exhibit higher thermal stability compared to metal oxide supports. Non-noble metal-based catalysts like Cu, Ni, and Co are favored for hydrogen production, while noble metals like Pt and Ru are used for specific operations. Additionally, monometallic catalysts with promoter additions of group 1 and 2 metals have been found to enhance metal oxide reducibility and prevent coking-induced deactivation. The article also delves into the importance of process variables like temperature, feed flow rate, and catalyst type in achieving high feed conversion and hydrogen yield. Furthermore, it explores the application of the Fischer-Tropsch process in synthesizing clean fuels using hydrogen obtained from various reforming techniques, employing reactors and catalysts like Fe-, Co-, and Ru-based ones. The catalytic activity is assessed based on reactant conversion and product selectivity, particularly focusing on the production of hydrocarbons.
