不同等级煤与油共炼的转化率差异及残渣分析
Analysis of solid residues from the co-processing of different rank coals and oils
摘要
Abstract
Anhui lignite, Liaoning lignite and Guizhou bitumite were co-processed with Murray residue ( MRAR) , Karamay residue ( KAR) and FCC slurry ( FCCS) in an autoclave with molybdenum naphthenate as catalyst, simulating the slurry-phase hydrogenation co-processing. The results show that for two lignites under different oil systems, the conversion of coal exceeds 83%. However, for Guizhou bitumite, a great difference is observed in the coal conversion between FCCS (67. 75%) and KAR (50. 31%) for co-processing. The solid residues after co-processing were analyzed by FT-IR and SEM, to determine the relative content of aliphatic and aromatic groups and the micro morphology. It is found that the solid residue derived from the KAR system possesses a low content of CH2/CH3 and a low substitution degree. Moreover, the solid residues obtained from two lignites with high coal conversion exhibit a looser structure and a higher dispersion of solid particles than that from bitumite with a low coal conversion.关键词
