Abstract

Process for the preparation of a catalyst comprising the steps of (a) preparing a slurry comprising clay, zeolite, a sodium-free silica source, quasi-crystalline boehmite, and micro-crystalline boehmite, provided that the slurry does not comprise peptised quasi-crystalline boehmite, (b) adding a monovalent acid to the slurry, (c) adjusting the pH of the slurry to a value above 3, and (d) shaping the slurry to form particles. This process results in attrition resistant catalysts with a good accessibility.

Claims (6)

1 . A process for the preparation of a catalyst comprising the steps of:

a) preparing a slurry comprising clay, zeolite, polysilicic acid, quasi-crystalline boehmite, and micro-crystalline boehmite, provided that the slurry does not comprise peptised quasi-crystalline boehmite,

b) adding a monovalent acid to the slurry,

c) adjusting the pH of the slurry to a value above 3, and

d) shaping the slurry to form particles.

2 . A catalyst composition comprising micro-crystalline boehmite, quasi-crystalline boehmite, zeolite, clay and silica.
