The mixtures were analyzed by Thermal Gravimetric Analyzer(TGA) and co-pyrolysis experiments. The results showed that torrefied rice husk had the advantage of raising conversion of the anthracite and bituminous coal by analyzing the TG curves,the increased rates were no more than 5%,but the torrefied rice husk had a negative effect on the conversion of lignite. In the experiments of co-pyrolysis,with the increase of torrefied rice husk in anthracite and bituminous coal,the solid products of the mixtures were lowered and the the gaseous products were increased,but the torrefied rice husk had an inhibitive effect on lignite. The addition of torrefied rice husk in the blends had the effect of accruing the content of H2 and reducing the content of CO2. So changing the percentage of torrefied rice husk in the mixtures had the effect of regulating the component of syngas.Read More
