Summary: | The invention discloses a method for preparing AL2O3 carrier. Said invention uses the farina as pore-expansion agent, which is added as powder after mixing other raw materials uniformly, and its added amount is 10-20wt% of alumina. Compared to present technique, said inventive alumina carrier has high strength, larger pore diameter, and centralized pore distribution, while said inventive method has simple process without special raw material and the cost of material and production are lower. The invention can be used as catalyst in the areas of oil refining, chemical industry and environmental protection, especially as the hydrogenation catalyst of heavy and residual oil. |
