Abstract
(EN)
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.

L'invention concerne un procédé de prétraitement de charbon pulvérisé et un procédé de gazéification de charbon pulvérisé. Le procédé de prétraitement de charbon pulvérisé comprend les étapes suivantes : (1) réalisation d'un élargissement de pores sur du charbon pulvérisé pour obtenir du charbon pulvérisé prétraité; (2) chargement d'ions de métal alcalin dans le charbon pulvérisé prétraité dans une condition d'échange d'ions pour obtenir du charbon pulvérisé chargé de métal alcalin. Le procédé comprend en outre le chargement d'un complexe de chrome dans le charbon pulvérisé chargé de métal alcalin obtenu dans l'étape décrite (2). Lors de la gazéification, le charbon pulvérisé chargé avec des catalyseurs de potassium et de potassium de métal alcalin obtenu par le procédé présente les avantages d'un taux d'élimination de soufre élevé, d'un taux de conversion de carbone élevé, d'un temps de réaction de gazéification court et d'une production de méthane élevée.
