Process for synthesizing a molecular sieve having the offretite structure and containing aluminum and gallium

摘要

A crystalline, gallioaluminosilicate molecular sieve having the offretite structure is synthesized by mixing a substantially gallia-free aluminosilicate hydrogel containing a templating or directing agent with a galliosilicate solultion substantially free of alumina to form a mixture and then crystallizing the resultant mixture, usually in 24 hours or less.
