Claims20
A method for the preparation of mordenite zeolite having a MOR framework comprising:
- forming a homogeneous aqueous mixture of water, a silica source, an aluminum source, an alkali metal source, an optional structure directing agent, and a water-soluble oxidized disulfide oil (ODSO);
- and
- heating the homogeneous aqueous mixture under conditions and for a time effective for hydrolysis and to form a crystalline zeolite as precipitate suspended in a supernatant, wherein the precipitate comprises mordenite zeolite.
