Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
65 words
A hydrocracking process which comprises contacting a hydrocarbonaceous feed in the presence of hydrogen at hydrocracking conditions with a catalyst comprising a crystalline solid having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, and mixtures thereof greater than about 6:1 and having the X-ray diffraction lines of Table 1.
Claim 2
Dependent Claim
65 words
A hydrocracking process which comprises contacting a hydrocarbonaceous feed in the presence of hydrogen at hydrocracking conditions with a catalyst comprising a crystalline solid having a mole ratio of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, and mixtures thereof greater than about 6:1 and having the X-ray diffraction lines of Table 1.
Claim 3
Dependent Claim
54 words
