催化裂化催化剂混仓生产技术的可行性研究

FEASIBILITY STUDY OF FCC CATALYST BLENDING TECHNOLOGY

对混仓型催化剂与整体型催化剂的物化性质与催化性能进行了对比研究。分析与评价数据表明,不同Y型沸石基础催化剂以及不同类型沸石(Y型和ZSM-5型)基础催化剂之间按整体型催化剂的沸石配比进行混仓,可以达到与整体型催化剂相当的物化性质和催化裂化反应性能,因而可以通过基础催化剂混仓来获取具有不同功能的催化裂化催化剂以满足炼油厂的实际需求。此外,还提出了基础剂配方设计及耐磨损性能等方面需要关注的问题。

The physicochemical properties and catalytic performances of the integrated FCC catalyst produced by traditional methods(contains a certain proportion of different zeolites)and the physical blending catalysts(from mixing the based catalyst which contains only Y zeolite or modified ZSM-5)with a close ratio as in the former were comparatively studied.The results showed that,at similar compositions,the physicochemical properties and catalytic performances of blended catalysts are close to the integrated one.Therefore,FCC catalysts could be flexibly tailor-made for refineries by blending base catalysts.In addition,some issues about the formulation and attrition property of base catalysts which should be cared were suggested.
