Pyrolysis Conversion of Waste into Carbon-Based Catalysts for Hydrogen Production
Short Introductive summary
Methane cracking is an environmentally friendly method of hydrogen production that, unlike other conventional processes such as Steam Methane Reforming, Partial Oxidation of Methane, and Dry Reforming of Methane, can convert methane into hydrogen without emitting GHGs. However, this process requires a high operating temperature of around 1200 ?. The use of metallic catalysts and carbon-based catalysts facilitates methane cracking at more moderate temperatures. Based on the literature, catalysts derived from carbon materials are more cost-effective and exhibit greater resistance to impurities and high temperatures compared to metallic ones. This study mainly focused on applying carbon-based catalysts derived from biomass and waste for the Catalytic Methane Decomposition (CMD) process. For this purpose, eight catalysts were produced from three carbon materials including wood, sewage sludge, and digestate (by-product from anaerobic digestion of agro-residues) through three processes of pyrolysis, leaching, and physical activation.
