Agricultural stalk is the most abundant biomass resource in China,producing nearly 600 million tons one year.The experiment with TGA coupled with Fourier transform infrared(FTIR) was performed for the pyrolysis of rice straw and cotton stalk.The effects of heating rate,particle size and mineral matter on the conversion of Cl-HCl during straw pyrolysis were studied.The results show that acid washing has no impact on rice straw chemical structure;when the heating rate increases,the yield of HCl increases,that...
