Abstract
A phosphorous-containing zeolite with structural type CON in its aluminosilicate or borosilicate form contains at most 10% by weight of phosphorous. A process for its preparation is described, starting from existing zeolites (SSZ-26, SSZ-33 or CIT-1) or from beta zeolites and an organic structuring agent or template which is 1-N,N,N-trimethyl adamantammonium hydroxide or 2-N,N,N-trimethyl adamantammonium hydroxide. The zeolite is used for catalytic cracking of hydrocarbon feeds.
