不同催化剂对渣油加氢反应产物分布的影响
Influence of Catalysts on Product Distribution of Residue Hydrotreating
摘要
Abstract
The influence of different catalysts on product distribution of residue hydrotreating in an autoclave with Tahe atmospheric residue (THAR) and Saudi Arabia light crude oil vacuum residue (ALVR) was studied.The results show that the catalyst activity and selectivity can be evaluated by the cracking conversion for unit coking (x1/xcoke) or the ratio of the cracking conversion to the unit condensation (x1/x2).It is consistent to the traditional understanding of residue hydrotreating.The catalysts influenced product distribution by providing active hydrogen atom to inhibit cracking of macromolecular radicals.There is different performance to inhibit coke formation in residue hydrotreating for different catalysts.The inhibition condensation sequence of catalysts is B>C>A and the maximum difference of the ratio of the cracking conversion to the unit condensation can reach 4.3.The influence of catalysts on residue hydrotreating was not only related to content and species of active metals,but also to the atomic ratio of hydrogenating component and surface structure of catalyst.关键词
