Effect of chemical fractionation treatment on structure and characteristics of pyrolysis products of Xinjiang long flame coal

The Xinjiang region is one of the most important energy bases in China. A demineralized coal treated by the chemical fractionation method will provide a promising approach to evaluate the inherent minerals catalytic performance in pyrolysis, especially which contains abundant alkali metals. The effect of ash removal on the physicochemical structure and pyrolysis characteristics of coal sample were explored, and the acetic acid, hydrochloric acid...
