Abstract:

CH4, CO, CO2 and NH3 in pyrolysis products of three kinds of anthracites were quantitatively analyzed and studied by means of TG-FTIR. The result showed that the start release temperature and release peak temperature of CH4 were gradually increased together with the reduction of the volatile matter content; CO release peak temperature of individual coal sample was basically the same. the start release temperature of CO2 was about 195℃, the release total amount of CO2 was increased with the increase of the volatile mat ters of coal sample, the temperature release law of NH3 was similar, but the release of NH3 of coal sample at 900℃ was not thoroughly reacted, the NH3 release amount of coal sample from Jiaozuo which has maximum volatile matter and nitrogen content was maximum, however, Longyan coal was minimum.
