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.

Method for manufacture of pure silica zeolites in the presence of ODSO

The present disclosure is directed to a method of manufacture of zeolite. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include zeolite with increased crystallinity relative to comparable sol-gel formulations without ODSO as a precursor. In additional embodiments, the rate of crystallization of the zeolite is greater relative to comparable sol-gel formulations without ODSO.

Method to synthesize crystalline materials in the presence of ODSO with improved zeolite crystallization rates and enhanced relative crystallinity

The present disclosure is directed to a method of manufacture of CHA framework crystalline materials of silica and a framework metal oxide, with the ability to reduce the amount of structure directing agent needed for synthesis. This is accomplished by using an improved sol-gel formulation including a water-soluble fraction of ODSO as an additional component. The resulting products include CHA framework crystalline materials of silica and a framework metal oxide, whereby a framework metal oxide can be an oxide of Al, Fe, B or Ga.
