摘要：
Process for the preparation of a catalyst comprising the steps of (a) preparing a slurry comprising clay, zeolite, and quasi-crystalline boehmite, provided that the slurry does not comprise peptised quasi-crystalline boehmite, (b) adding a monovalent acid to the slurry, (c) adding a silicon source to the slurry, and (d) shaping the slurry to form particles. This process leads to a catalyst with high accessibility and high attrition resistance.
