Abstract: Rice husk was chosen as a model compound by microwave heating with silicon carbide (SiC) and carbon residue as microwave absorbent. A novel concept of fast microwave assisted pyrolysis of rice husk for syngas production in the presence of microwave absorbents was presented and examined. Experimental results showed gas was the main product in the fast microwave assisted pyrolysis of rice husk using microwave absorbent, the highest yield was 53%, The primary components of gas product were H₂, CO₂, CO, and CH₄, which accounted for more than 97% of pyrolysis gas volume. The content of H₂ was higher than 38%, and it reached 48.12% when carbon residue was used. The optimal ratio of carbon residue to rice husk was determined as 1:1, and the syngas (H₂ + CO) content is greater than 60%, so fast microwave assisted pyrolysis using microwave absorbent is an effective heating method for biomass gasification.
