Abstract
The present disclosure is directed to a method to synthesize pure silica zeolites. This is accomplished by using an improved sol-gel formulation including a water-soluble fraction of ODSO as an additional component together with precursors and reagents effective for synthesis of pure silica zeolite.
Claims20
A method for synthesis of pure silica zeolite comprising:
- forming a homogeneous aqueous mixture of an effective amount of water-soluble oxidized disulfide oil (ODSO), and precursors and reagents effective for synthesis of pure silica zeolite;
- and
- heating the homogeneous aqueous mixture under conditions and for a time effective to form a precipitate suspended in a supernatant, wherein the precipitate comprises pure silica zeolite.
