ABSTRACT:
A crystalline, galliosilicate molecular sieve having the offretite structure comprises silicon, gallium, oxygen and substantially no aluminum. The molecular sieve is synthesized by crystallizing a hydrogel reaction mixture which is preferably formed by mixing a substantially alumina-free galliosilicate hydrogel containing an offretite selective templating or directing agent with a galliosilicate solution substantially free of alumina. The crystallized molecular sieve can be employed, after activation by removing the templating agent and reducing its alkali metal content, as a component of a catalyst which is suitable for use in a variety of chemical conversion processes, preferably hydrocarbon conversion processes.
