| titleOfInvention | Improved diesel hydrocracking catalyst carrier and preparation method thereof |
| abstract | The invention discloses an improved diesel hydrocracking catalyst carrier and a preparation method thereof, wherein the carrier comprises the following raw materials in percentage by weight: 3-35% of molecular sieve and 5-75% of gamma-Al 2 O 3 15-75% of amorphous silica-alumina and 7-40% of binder; the specific surface area of the carrier is 200-450 m 2 Per g, total pore volume of 0.35-0.75 cm 3 (ii) in terms of/g. In the invention, a molecular sieve without a template agent is added in the process of preparing the molecular sieve and alumina composite material, and in the mixed solution, NH4 generated by the reaction of aluminum salt and ammonia water + Exchanging with alkali Na + for balancing negative charge of molecular sieve skeleton, and calcining organic template agent and NH in molecular sieve 4 + The removal is carried out, so that the ammonium exchange and the template agent of the zeolite molecular sieve are completed in the process of preparing the composite material, the template agent does not need to carry out the ammonium exchange and the template agent separately on the molecular sieve, the template agent has supporting and protecting functions on the pore structure of the molecular sieve, and the hydrocracking catalyst prepared by using the carrier can obviously reduce the condensation point of diesel oil fraction and improve the cetane number of the diesel oil on the premise of ensuring high yield of the diesel oil. |
