Gasification Process and Synthesis Gas

The video tutorial explains the thermochemical conversion process, focusing on gasification, which transforms biomass into synthesis gas. This gas, rich in hydrogen and carbon monoxide, is converted into liquid fuels. The process involves preparing feedstock, managing byproducts, and removing contaminants. Technological advancements have improved efficiency and understanding, leading to industry deployment of gasification technologies for clean, renewable fuels.
