| titleOfInvention | Preparation method of high-selectivity benzene alkylation strip catalyst |
| abstract | A preparation method of a high-selectivity benzene alkylation bar-shaped catalyst selects an MFI zeolite molecular sieve with high silica-alumina ratio as a matrix of the catalyst; extruding and molding a hydrolysate of acidified silicone grease and the MFI zeolite molecular sieve with high silica-alumina ratio, treating the molded catalyst by using a separation mother liquor obtained when the MFI zeolite molecular sieve with high silica-alumina ratio is hydrothermally crystallized, and adding boride into the separation mother liquor; and (3) converting the mother liquor treated MFI zeolite molecular sieve extrusion strip molding with high silica-alumina ratio into a hydrogen type alkylation catalyst by adopting an ion exchange method. The method uses the mother liquor generated in the hydrothermal synthesis of the MFI zeolite molecular sieve with high silica-alumina ratio for treating the formed strip catalyst, thereby not only recovering useful components in the mother liquor and dredging the pore channel of the catalyst, but also reducing the environmental pollution in the full production chain of the alkylation catalyst. When the mother liquor is used for treating and forming the catalyst, a proper amount of boride is added into the mother liquor, so that the mechanical strength of catalyst particles is improved, and the service life of the catalyst is prolonged. |
