Catalytic Gasification of Biomass Over Fe-MgO Catalyst


Given the significant abundance of non-food biomass resources, rural areas are endowed with a great potential for development of biomass energy systems which can make a significant contribution to economic development without public health issues. In this work, an experimental work done on air-steam gasification of biomass in precence of Fe/MgO for hydrogen rich gas production and CO2 reduction. As reactor temperature increased from 800 to 1000 oC, the tar and char yields decreased from 6.4 to 1.6 % and 18.4 to 5.6 %, respectively, while the syngas yield increased from 75.2 to 92.8 %. With the increase of C/B from 0.1 to 1.0, H2 concentration increased by 39 % while the CO2 concentration decreased from 35.4 vol% to 20.4 vol%.
