| Abstract: | The flash pyrolysis behaviors of Shenfu coal,Dongsheng Vitrinite(DS-V),and Inertinite(DS-I)and the technological properties of their chars were measured in N2 under atmospheric pressure in wire-mesh flash pyrolysis reactor, As the pyrolysis end temperature and heating rate increased, the weight loss increased and the combustion characteristic temperature moved to higher temperatures. The gasification rate increased as heating rate increased and had a maximum value in the range of pyrolysis end temperatures.The weight loss of DS-V was higher than that of DS-I. The flash pyrolysis process changed the thermal properties of DS-V and made it swell with rich thin-wall open pore.Its char combustion and gasification properties were better than those of DSD-I. |
