Abstract
Disclosed are a pulverized coal preprocessing method and a pulverized coal gasifying method. The pulverized coal preprocessing method comprises the following steps: (1) performing pore broadening on pulverized coal to obtain preprocessed pulverized coal; (2) loading alkali metal ions into the preprocessed pulverized coal under an ion exchange condition to obtain alkali metal loaded pulverized coal. The method further comprises loading a chrome complex into the alkali metal loaded pulverized coal obtained in described step (2). In gasification, the pulverized coal loaded with alkali metal potassium and chrome catalysts obtained by the method has the advantages of high sulphur removal rate, high carbon conversion rate, short gasifying reaction time and high methane production.
