PowerPoint Presentation Author: Gasification produces a synthesis gas with usable energy content by heating the biomass with less oxygen than needed for complete combustion. GASIFICATION • Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. Biomass Gasification converts Agro Waste (like Bamboo, coconut shells, sawdust, briquettes etc) into producer gas, which can be used for thermal or power generation applications. Hydrogen production from biomass via gasification can be an auspicious alternative for future decarbonized applications, which are based on renewable and carbon-dioxide-neutral produced hydrogen. In Western European cities, town gas was produced by the gasification of coal before natural gas became widely available.
