摘要

采用浸渍法制备了负载型超强碱KF/γ-Al_2O3催化剂，SEM和EDS表征发现KF/γ-Al_2O3催化剂是孔径较小的不规则颗粒，KF在催化剂表面均匀负载．KF/γ-Al_2O3催化胜利碱洗褐煤的醇解活性研究表明，醇解收率提高约一倍．这意味着超强碱催化剂具有更多的反应活性位点，促进煤有机质大分子的醇解反应．经傅里叶变换红外光谱(FTIR)分析，发现催化醇解生成了更多的酚类化合物；经实时直接分析质谱(DART-MS)分析，催化醇解提高了醇解反应的亲核反应效率，促进了芳核和脂链上的侧链解离．说明了胜利褐煤中的氧原子主要存在于芳香结构单元上．

Abstract

KF/γ-Al_2O3 catalyst was prepared by impregnation method. It was found that the KF/γ-Al_2O3 catalyst was irregular particles with small pore size

and KF was uniformly supported on the catalyst surface by SEM and EDS characterization. The study on the alcoholysis activity of KF/γ-Al_2O3 catalyzed victorious alkali washed lignite showed that the alcoholysis yield was approximately doubled. The super-alkali catalyst provides more reactive sites

which can promote the alcoholysis reaction of coal organic matter macromolecules. The alcoholysis products with and without the catalyst were studied by fourier transform infrared spectroscopy(FTIR)

and it was found that more phenolic compounds were generated. Catalytic alcoholysis improves the nucleophilic reaction efficiency of the alcoholysis reaction and promotes the dissociation of side chains on the aromatic nuclei and lipid chains by real-time direct analysis mass spectrometry(DART-MS). It is found that the oxygen atoms in Shengli lignite are mainly present on the aromatic structural units.
