Abstract
Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions and high catalytic cracking activity, a method for their preparation and their use as FCC catalysts. More particularly, the new SAPOs have a high silica:alumina ratio and favorable Si atom distribution. The new SAPOs may have a small crystal size and may be synthesized from a single- phase synthesis solution.
