It is an new support material for catalyst. resistant to high temperature, high pressure and strength

1.Performance characteristics

Activated ceramic ball is a new support material of catalyst. It added a small amount of transition metal oxide into the inert ceramic ball. It has the property of high-temperature resistance .high pressure and strength of the inert ceramic ball to filtrate. disperse vapor-liquid coverage and support the catalyst, In addition, it has adequate catalytic activity when used in the process of olefin hydrogenation desulfurization, denitrification to help catalysis.If been set on the top of catalysts bed in the reactor of distillates hydrotreating, hydrocracking, reforming pre-hydrogenation and hydrogenation of benzene hydrogenation, the activated ceramic ball make the olefin in the secondary processing fraction pre-hydrogenated and keep the catalyst from cokings. similarly, if been set on the bottom, it can remove the thio-alcohol caused in the reaction process. on the whole, using the activated ceramic ball can not only save the space in reactor, but also protect the catalyst from poisoning or sintering. consequently prolong the service life of catalyst.
