EFFECTS OF IRON-BASED CATALYST ON QUICK COAL LIQUEFACTION AT HIGH TEMPERATURE
摘要
Abstract
The effects of two kinds of iron-based catalyst on quick coal liquefaction at high temperature (QCLHT) are investigated by using a micro-autoclave reactor when Yanzhou coal is selected as object of study. The results shows that the pyrolytic behavior of the coal is influenced slightly when Fe2 S3 and high dispersion iron-based catalyst are respectively supported in the coal; hydrogen can participating in coal liquefaction more easily when the coal is impregnated by Fe2 S3, at the same time, a lighter distribution of products of coal liquefaction can be realized; under the condition of excellent and sufficient hydrogen donating solvent, the hydrogen donating rate of solvent is much higher than that of hydrogen conversion and the role of catalyst is not obvious. The role of elemental sulfur is in relation to its combination form with the iron series main catalyst according to the comparison of the catalytic results of QCLHT when high dispersion iron-based catalyst with S as additive and impregnated Fe2 S3 are selected as catalyst respectively.关键词
