The rice straw,wheat,corn,cotton and rape five crop stalks were used as the research object,using the tube furnace for its pyrolysis research,and the difference of pyrolysis gas production was discussed,research indicates:Among the five biomass stalks,the highest gas yield of rape straw was 0.28 L/g;and the contents of CO and H2 in the pyrolysis gas were 31.6% and 26.3%;The raw material calorific value and combustible gas low calorific value of the rape straw were 12345.84 kJ/kg and 10.51 MJ/m~3,and the values were the highest among the five kinds of straw. Analysis shows that SEM images of fi...
