Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
97 words
In a hydrocarbon conversion process wherein at least one hydrocarbon is contacted with a conversion catalyst under conversion conditions, the improvement comprising contacting said hydrocarbon with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from a group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 2
Dependent Claim
97 words
In a hydrocarbon conversion process wherein at least one hydrocarbon is contacted with a conversion catalyst under conversion conditions, the improvement comprising contacting said hydrocarbon with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from a group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 3
Dependent Claim
11 words
