The activated alumina sphere is a porous solid material, which has the advantages of large specific surface area and pore volume, adjustable pore distribution, high mechanical strength after molding, good thermal stability, abundant source and low price, and is widely used in the field of catalysis. Used as a catalyst carrier.

Used as a catalyst carrier.
The activity of the activated alumina ball catalyst was evaluated in a self-made fixed bed high pressure continuous reactor. The catalyst (0.115 ml) was previously reduced in an H 2 gas stream (100 ml/min) at 015 MPa at 400 ° C for 4 h, and then subjected to ethylbenzene hydrogenation under the conditions of an ethylbenzene volume space velocity of 1133 h-1, a H2 flow rate of 100 ml/min, and a pressure of 110 MPa. Catalytic reaction. Product analysis was performed on a GC2950 gas chromatograph (SGE2AC20 column) equipped with a hydrogen flame detector.
