The present disclosure is directed to a method of manufacture of low silica zeolite having MFI framework, such as ZSM-5. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include low silica zeolite having MFI framework, whereas in the absence of the ODSO, the resulting products are zeolite impurities including analcime.

This disclosure describes enantiomerically enriched chiral molecular sieves and methods of making and using the same. In some embodiments, the molecular sieves are silicates or germanosilicates of STW topology.

A hydrocracking catalyst having a support of a composite of mesoporous materials, molecular sieves and alumina, is used in the last bed of a multi-bed system for treating heavy crude oils and residues and is designed to increase the production of intermediate distillates having boiling points in a temperature range of 204? C. to 538? C., decrease the production of the heavy fraction (>538? C.), and increase the production of gasoline fraction (<204? C.). The feedstock to be processed in the last bed contains low amounts of metals and is lighter than the feedstock that is fed to the first catalytic bed.
