摘要
描述了工业油品精制催化剂开发过程中所应考虑的六大要素,讨论了这些要素对催化剂性能提高的影响:包括通过各种技术调节手段,如无机助剂改性、有机助剂改性、超声辅助手段等实现对催化剂的理化性质调控,如改善酸性质、比表面积、孔结构、堆积密度等;通过这些技术手段还可调变金属-载体相互作用、活性金属的分散度和硫化度、MoS_2(WS_2)片晶长度和叠层数等,实现对催化活性中心形貌的控制;通过原材料选取及生产过程优化,降低催化剂成本;通过催化剂形态合理设计,提高催化剂体系的活性及稳定性。介绍了在工业油品精制催化剂技术进步中一些技术调节手段的应用,给出了系列商品催化剂活性进步的历程,并指出了提高催化剂性能的一些新思路,最后介绍了一些新的材料及方法在油品精制上的应用。
Six major factors in the development process of industrial oil refining catalysts were introduced in this paper,and their influence on the catalyst performance were discussed as well as the regulations of the physicochemical properties of catalysts by means of various techniques,including using inorganic additives modification,organic additives modification,ultrasonic auxiliary means etc. to improve the acid properties,specific surface,pore structure,and bulk density etc. The interaction of the support and metal,the dispersion and curing degree of active metal,MoS_2（WS_2） in length and number of layers of lamellae could be adjusted through these techniques,which realized the control of the morphology of catalytic activity center. Through the selection of raw materials and the optimization of the production progress,we could reduce the catalyst cost. The activity and stability of catalyst system could also be improved by rationally designing the catalyst form. The application of some technical and regulation means in the progress of industrial oil refining catalysts was introduced,then the course of improving the commercial catalyst activity was given,and some new ideas to improve the performance of catalysts was pointed out. Finally,some new materials and methods that used in oil refinery were also mentioned.
