摘要： Process for the preparation of a catalyst by adding, clay, boehmite, a first silica to form a slurry, digesting the slurry with a monoprotic acid to a pH of less than 4, adding one or more zeolites, adding a rare earth component to the slurry and mixing, adjusting the slurry pH to below 4 with monoprotic acid, adding a second silica anywhere in the preceding steps, destabilizing the slurry by raising the pH, shaping and collecting the resulting catalyst, wherein the resulting catalyst has enhanced mesoporosity.
