| titleOfInvention | A kind of C5 and/or C9 petroleum resin two-stage hydrotreating catalyst and its preparation method and application |
| abstract | The invention provides a C5 and/or C9 two-stage hydrofinishing catalyst and a preparation method and application thereof, belonging to the technical field of petrochemical industry. In the present invention, by performing alkali exchange on the molecular sieve, the silicon without the component molecular sieve skeleton is washed away, the pore structure of the molecular sieve is moistened, and the dispersibility of the impregnated active component is improved, so as to facilitate the exertion of the function of the active component; and then the acid exchange is performed to increase the The acid site and acid value strength on the molecular sieve framework can improve the hydrogenation performance of the catalyst, reduce the diene value after the first-stage hydrogenation and the bromine value of the petroleum resin after the second-stage hydrogenation; the present invention combines the modified molecular sieve, base material, The binder and the pore-enlarging agent are mixed, the resulting mixture is shaped, and the shaped object is first calcined to form new channels under the action of the pore-enlarging agent to obtain a double mesoporous carrier; the double mesoporous structure can convert a small amount of unsaturated Diolefins are hydrogenated and saturated, thereby prolonging the service life of the catalyst. |
