| titleOfInvention | A kind of catalyst for preparing cumene by hydrogenolysis of α,α-dimethylbenzyl alcohol and its preparation method and application |
| abstract | The invention relates to a catalyst for preparing cumene by hydrogenolysis of α,α-dimethylbenzyl alcohol and a preparation method thereof. The catalyst comprises 35-50wt% of copper oxide, 10-20wt% of zinc oxide, 20-35wt% of zirconia, 2-10wt% of bismuth oxide and 1-5wt% of sodium silicate. The preparation method of the catalyst adopts a co-current co-precipitation method, and the mixed salt solution of copper salt, zinc salt, zirconium salt and bismuth salt is co-current with an alkaline precipitant to carry out co-precipitation reaction and aging to obtain a slurry, and the slurry is filtered. , washing, drying and roasting to obtain catalyst powder, the catalyst powder is mixed with a certain amount of sodium silicate, forming aids and adhesives, and then extrusion molding is carried out, and the formed catalyst is subjected to secondary roasting to obtain Final finished catalyst. The catalyst prepared by the method has the characteristics of high activity and selectivity, good hydrothermal resistance and strong sintering resistance. |
