BIOMASS GASIFICATION FOR HYDROGEN PRODUCTION, AN OVERVIEW OF THE PROCESS USING VARIOUS RAW MATERIALS

Climate change, environmental pollution, population growth and overwhelming amounts of waste have led to the need to identify alternative fuels to replace fossil fuels. The gasification process of biomass residues from agriculture and agro-industry represents a suitable source for energy recovery through the production of syngas, including H2, CO and CH4. The gasification processes are carried out in area 500 °C ÷ 1000 °C. Various types of gasifiers were examined, in fixed bed and fluidized bed, following the gasification process and the contribution of specific gasification agents. The oxidation agents used in the biomass gasification process are: air, CO2, steam, O2. The effect and type of catalysts used were followed from the perspective of the highest possible percentage of hydrogen. This report analyzed the production of syngas, especially hydrogen, through gasification by comparing and analyzing the results of various types of biomass and aimed to bring a globalist approach to the production of hydrogen-rich syngas based on current technologies.
