Detailed information

 

(1)   Characteristics of product
ZT-ACB Active ceramic ball is another novel supporting packing of reactor, witch is commonly developed by our company and Dalian institute of chemical physics, Chinese academy of sciences. In fact, it is prepared on the basis of the inert alumina by adding the micro-pore amount of transition metal oxide. There are excellent properties of inert ball for ZT-ACB active ceramic ball (the heat resistance, mechanical strength, filtration or dispersion of gas or liquid, and covering or supporting of catalyst, etc.). In addition, there is well property of catalytic activity, which can play the role of catalyst promoter in many processes (olefin hydrogenation, desulfurization, and denitrification, etc.). During the processes of hydrofining, hydrocracking, reforming pre-hydrogenation, and benzene hydrogenation for oil cut fractions, if ZT-ACB active ceramic ball is loaded above the catalyst layer in the reactor, it can induce the mono-olefins or dienes to hydrogenate initially in the secondary operation of crude oil. In contrast, if ZT-ACB active ceramic ball is loaded in the bottom of catalyst layer, it can also remove the mercaptan, which is produced within some reactions. Therefore, it can not only improve the space usage ratio, but also on some extent to protect catalyst from poisoning or agglutinating with ZT-ACB active ceramic ball, and it can prolong the lifetime of catalyst utilization.
