APPLICATION:

As a essential bottom filling material, inert alumina ball used on reflect the device, adsorption and absorption centers devices of hydrocracking unit, catalytic reforming unit, isomerization unit , demethylation devices in the oil chemical plants, oil refineries, alkyl benzene plants, aromatic plants, ethylene plants, natural gas plants, chemical plants, methanol plants and ammonia plants, played the role of buffer and filter. As reactor support and cover material of catalyst, it can buffer impact which come from the liquid and gas in reactor to catalysts, play a protective role to catalyst and improve the distribution of liquid and gas in reactor. (It used in a equipment which is seem desulfurization tower for Petroleum equipment plant)
