The activity Ciqiu is made ​​of a small amount of transition metal oxide in the the inert Ciqiu added, both having the inert Ciqiu high temperature, high pressure and high mechanical strength characteristics, from filter, covered with a dispersing vapor, supporting the role of the catalyst, but also hassome catalytic activity in olefin saturation, desulfurization, denitrification process in a co-catalyst. Distillate hydrotreating, hydrocracking, reforming pre-hydrogenation and hydrogenation of benzene hydrogenation reactor the intrinsic catalyst bed top loading SW active Ciqiu, secondary processing of the olefins in the feedstock oil can be obtained preliminary plus hydrogen, thereby reducing catalyst coking; filling SW active Ciqiu in the bottom of the catalyst bed, can be removed, but having a certain extent protect the catalyst poisoning and sintering effect, thereby prolonging the life of the catalyst.


Product Features:
Having inert Ciqiu the high temperature, high pressure and high mechanical strength characteristics, from filter, covered with a dispersing vapor, supporting the role of the catalyst, but also has some catalytic activity.
Applications:
Applied to the distillate hydrotreating, hydrocracking, reforming the pre-hydrogenation and the hydrogenation of benzene hydrogenation reactor.
