Claims7
A hydrocracking process comprising contacting a hydrocarbonaceous feedstock under hydrocracking conditions with hydrogen and a hydrocracking catalyst composition comprising a zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from boron oxide, or mixtures of boron oxide with aluminum oxide, gallium oxide or iron oxide, greater than 10:1 and wherein the amount of aluminum is less than 0.10% by weight and having the x-ray diffraction lines of Table 1(b), and an effective amount of a hydrogenation catalyst comprising a Group VIB metal, Group VIII metal or mixtures thereof.
A catalytic cracking process comprising the step of contacting a hydrocarbon feedstock in a reaction zone under catalytic cracking conditions in the absence of added hydrogen with a catalyst comprising a zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from boron oxide, or mixtures of boron oxide with aluminum oxide, gallium oxide or iron oxide, greater than 10:1 and wherein the amount of aluminum is less than 0.10% by weight and having the x-ray diffraction lines of Table 1(b).
