Abstract
Abstract The present invention relates to a zeolite, designated as ECR-17, having a structure similar to CSZ-1 and a silica to alumina ratio greater than about 7. The invention also relates to a catalyst containing that zeolite or hydrocarbon conversion process, notably catalytic cracking, using that catalyst.
