Activated Alumina Precious Metal Catalyst Carrier
Activated alumina is except widely used as a functional material for desiccant and water filtration media, activated alumina is also used as a catalyst, with roles as the catalyst itself, as well as an inert carrier, or substrate for other catalysts.Activated alumina catalyst can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas, hydrogen production, air separation plant, instrument air drying machine, fluoride treatment in hydrogen peroxide.
Activated alumina noble metal catalyst carrier is a new kind of catalyst carrier and covering filler.It not only has the characteristics of high temperature, high pressure and high mechanical strength of inert ceramic ball, but also has certain catalytic activity.It can catalyze olefins saturation, desulfurization and denitrification processes.For the hydrofining, hydrocracking, reforming prehydrogenation and benzene hydrogenation of distillate oil, the active alumina ball is filled on the top of the catalyst bed, and the olefins in the secondary processing raw oil can be preliminarily hydrogenated.Reduce catalyst coking.The use of activated alumina ball can not only effectively improve the space utilization of the reactor, but also protect the catalyst from poisoning and sintering to a certain extent, thus prolonging the service life.
