This product mainly uses the AI2O3 as raw material, uses the ultra fine powder, and so on static pressure, the forming machine molding and the high temperature roasting. High temperature high pressure, low water absorption, chemical stability, acid and alkali corrosion and other organic solvents, can withstand the sudden changes in temperature.
It is widely used in petroleum chemical factory, chemical factory, factory, factory, aromatic benzene ethylene plant and gas plant hydrogenation cracking device, refining unit, catalytic reforming unit, isomerization unit and demethylation device bottom filling material. Support covering material and tower filler as catalyst, molecular sieve, desiccant, etc. in the reactor.
