Research about the Pyrolysis Products Characteristics of Corn Stalk with Different Catalysts

The experimental study on pyrolysis of corn stalk was done in the tube furnace.The contrast experiments had carried out respectively under the condition of pure corn stalk and adding catalyst(CaO,CFBB slag,CFBB ash).The experimental results showed that the volume content of CO2 all declined significantly,while the combustible components was increasing after adding the catalyst.Through experiments also found that it could get the highest gas yield and the lowest liquid yield by adding CFBB ash.It could get the highest gas calorific value by adding CFBB slag which compared with pure corn stalk pyrolysis,the gas calorific value increase of 75.4 %.
