Abstract
Hydrocracking catalyst composition comprising an optional metal hydrogenation component supported on a carrier comprising a zeolite of the faujasite structure having a unit cell size in the range of from 24.10 to 24.40 Å, a bulk silica to alumina ratio (SAR) above about 12, and a surface area of at least about 850 m2/g as measured by the BET method and ATSM D4365-95 with nitrogen adsorption at a p/po value of 0.03.
Claims31
A middle distillate selective hydrocracking catalyst composition which comprises a metal hydrogenation component selected from the group of metals consisting of molybdenum, tungsten, cobalt, nickel and combinations of two or more thereof supported on a carrier comprising an amorphous binder component and from 2 to 80% by weight, based on the total weight of the carrier, a zeolite of the faujasite structure having a unit cell size in the range of from 24.14 to 24.38 Å, a bulk silica to alumina ratio (SAR) above about 12, a surface area of at least about 850 m2/g as measured by the BET method and ATSM D 4365-95 with nitrogen adsorption at a p/po value of 0.03, and a micropore volume of at least about 0.28 ml/g.
A process for the conversion of a hydrocarbonaceous feedstock into lower boiling materials, which comprises contacting the feedstock with hydrogen at elevated temperature and pressure in the presence of a hydrocracking catalyst composition which comprises a metal hydrogenation component selected from the group of metals consisting of molybdenum, tungsten, cobalt, nickel and combinations of two or more thereof supported on a carrier comprising an amorphous binder component and from 2 to 80% by weight, based on the total weight of the carrier, a zeolite of the faujasite structure having a unit cell size in the range of from 24.14 to 24.38 Å, a bulk silica to alumina ratio (SAR) above about 12, and a surface area of at least about 850 m2/g as measured by the BET method and ATSM D 4365-95 with nitrogen adsorption at a p/po value of 0.03, and a micropore volume of at least about 0.28 ml/g.
A composition comprising:
- a first zeolite of the faujasite structure having a first zeolite unit cell size in the range of from 24.24 to 24.38 Å;
- a bulk silica to alumina molar ratio in the range of from 20 to 100;
- and a surface area of at least 850 m2/g.
