Abstract
The present disclosure is directed to a method of manufacture of faujasite zeolite including zeolite Y. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include faujasite zeolite, and yields can be increased relative to comparable sol-gel formulations without ODSO.
