Abstract: Composition of matter suitable as a catalyst (base) in hydroprocessing comprising a crystalline aluminosilicate zeolite and a binder wherein the crystalline aluminosilicate comprises a modified Y zeolite having a unit cell size below 24.35 ANGSTROM , a degree of crystallinity which is at least retained at increasing SiO2/Al2O3 molar ratios, a water adsorption capacity (at 25 DEG C and a p/po value of 0.2) of at least 8% by weight of modified zeolite and a pore volume of at least 0.25 ml/g wherein between 10% and 60% of the total pore volume is made up of pores having a diameter of at least 8 nm. The invention also relates to hydroconversion catalysts and processes based on said compositions of matter.

Abstract: Silver catalysts providing improved selectivities for the oxidation of ethylene to ethylene oxide are prepared by (a) subjecting a catalyst comprising from about 1 to about 35 percent by weight of silver on a porous refractory catalyst support to a stabilization treatment, and (b) depositing from about 0.00004 to about 0.008 gram equivalent weights per kilogram of total catalyst of ions of one or more of the alkali metals potassium, rubidium or cesium on the stabilized catalyst.

Abstract: A process for converting hydrocarbon oils into products of lower average molecular weight and lower average boiling point comprising contacting a hydrocarbon oil at elevated temperature and pressure in the presence of hydrogen with a catalyst comprising a modified Y zeolite having a unit cell size below 24.45 ANGSTROM , a degree of crystallinity which is at least retained at increasing SiO2/Al2O3 molar ratios, a water adsorption capacity (at 25 DEG C and a p/po value of 0.2) of at least 8% by weight of modified zeolite and a pore volume of at least 0.25 ml/g wherein between 10% and 60% of the total pore volume is made up of pores having a diameter of at least 8 nm, an amorphous cracking component, a binder and at least one hydrogenation component of a Group VI metal and/or at least one hydrogenation component of a Group VIII metal. The invention also relates to catalyst compositions suitable for use in said process.
