高温煤焦油结构组成对浆态床加氢裂化性能的影响
Effect of structure of high temperature coal tar in slurry-bed hydrocracking
摘要
Abstract
A typical high temperature coal tar was selected as raw material for slurry-bed hydrogenation cracking test. Mean molecular structure of more than 360 ℃ heavy oil of the coal tar and hydrogenation heavy oil were analyzed by element analysis,SEM and 1H NMR. The carrying coke effect of the powdered catalyst was studied. The result shows that,aromatic degree of the high temperature coal tar is high,the quantity and relative molecular mass of the four components distribute continuously,and all these are good for asphalt dispersion stably. The coking tendency is small because the asphaltene is light. After hydrocracking,more than 360 ℃ heavy oil yield was reduced by 20.1 percentage,and the structure composition was lighter obviously, which was a good recycle oil. Because of large surface,catalyst worked as coke center to absorb the most of the coke. There was no wall phase coke formed.关键词
