ABSTRACT:
This invention relates to hydrocarbon conversion processes using novel molecular sieve compositions as the catalyst. These molecular sieves contain chromium in the framework structure along with aluminum and silicon. The process of preparing the chromium-containing molecular sieves involves contacting a starting molecular sieve with a solution or slurry of a fluoro salt of chromium under effective process conditions to provide for aluminum extraction and substitution of chromium.
