Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 52 words
A process for the conversion of a hydrocarbon­aceous feedstock having an end boiling point of at most 330 °C, which process comprises contacting the feed­stock with a zeolitic catalyst comprising a zeolite with a pore diameter of 0.3 to 0.7 nm at a temperature above 500 °C during less than 10 seconds.
Claim 2
Dependent Claim 52 words
A process for the conversion of a hydrocarbon­aceous feedstock having an end boiling point of at most 330 °C, which process comprises contacting the feed­stock with a zeolitic catalyst comprising a zeolite with a pore diameter of 0.3 to 0.7 nm at a temperature above 500 °C during less than 10 seconds.
Claim 3
Dependent Claim 21 words
