Feedstock Preparation: The raw material is pretreated to remove impurities and may be pulverized to increase surface area. Reaction Initiation: The pretreated feedstock is introduced into a gasifier where it reacts with a gasifying agent (such as steam, oxygen, or air) in the presence of a catalyst. Syngas Formation: The catalytic reactions convert the feedstock into syngas. The catalyst helps in breaking down complex molecules and enhances the formation of desired products. Gas Cleanup: The produced syngas is often cleaned to remove particulates, sulfur compounds, and other contaminants.
