Abstract

Abstract: The production of combustible gas from sawdust using microwave pyrolysis at a low-temperature of 450-600 ℃ was carried out. Variation of the gases composition was analyzed during the pyrolysis process. The effects of pyrolysis temperature, different kinds of catalysts, and different amounts of K₂CO₃ on the changes of components in combustible gas were studied. The results showed that under the conditions of pyrolysis temperature 550 ℃ and 20% amounts of K₂CO₃, the maximum yield of combustible gas was 62.65% with low heating value (LHV) of 14.05 MJ/m³. The combustible gas with high H/C ratio could be obtained under the catalysis of K₂CO₃.

Key words: microwave pyrolysis, low-temperature, combustible gas, gasification
