焦化蜡油中芳香分的催化裂化特性及其对饱和分裂化性能的阻滞作用
Catalytic cracking performance of aromatics in coker gas oil and retardation effect on saturates
摘要
Abstract
Aromatics were separated from coker gas oil ( CGO) using the furfural extraction. The catalytic cracking perform-ance of aromatics and the retardation effect on saturates were investigated. The results show that the furfural has good extrac-tion effect on aromatic hydrocarbons from CGO, which weakens the competitive adsorption and retardation effect of polycyclic aromatics on the saturated hydrocarbons. As a result, the raffinate oil has 15. 3% higher conversion than CGO, while the ex-tracted oil has 16. 1% lower conversion than CGO. Increasing the ratio of catalyst to oil can significantly enhance the conver-sion of extracted oil and yields of desired products. And the effect of mass space velocity is less. The influence of reaction temperature is the least compared to the above two factors. The extracted oil is not only difficult to catalytic cracking, but al-so hinders the effective catalytic cracking of saturates, which results in the declined feedstock conversion and reduces desired products yield. Consequently, the polycyclic/fused aromatics are one of the key factors restricting the effective catalytic cracking of CGO.关键词
