| 发明名称 | Method of producing FCC catalysts with reduced attrition rates | ||
| 摘要 | FCC catalysts having improved attrition resistance are provided by mixing a cationic polyelectrolyte with either zeolite crystals or a zeolite-forming nutrient and/or a matrix material, prior to or during formation of a catalyst microsphere. | ||

| 主权项 | 1. An FCC zeolite-containing catalyst microsphere, the microsphere comprising zeolite Y, the microsphere having been formed from a slurry comprising a matrix and at least one of a zeolite-forming nutrient or zeolite crystals, the slurry having been mixed with, prior to or during formation of the microsphere, a cationic polyelectrolyte in an amount from 0.005 to 0.5 wt. % relative to a total weight of the matrix and the zeolite-forming nutrient or the zeolite crystals in the slurry. | ||
