Tongchuan oil shale pyrolysis by TG-FTIR

Oil shale is an important alternative energy,it has great comprehensive development and utilization of potential.In this paper,With Tongchuan oil shale as the research object, themogravimetry and Fourier transform infrared Spectroscopy(TG-FTIR) is used to explore separation characteristics of the oil-shale pyrolysis Gaseous product in conditions of different atmosphere,and demineralization.Research shows that,at Hydrogenation atmosphere,the absorption intensity of CO_2 significantly reduces,the absorption strength of CO,C_nH_m and CH_4 increase apparently;After the ash free,the absorption intensity of CO,C_nH_m and CH_4 are weakened dramatically,separation quantity is reduced.
