Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
26 words
A method of substantially removing adsorbed benzene from an adsorbent which comprises converting the adsorbed benzene to cyclohexane, and desorbing the cyclohexane with a hydrocarbon desorbent.
Claim 2
Dependent Claim
36 words
The method of claim 1 wherein the adsorbed benzene is obtained by contacting a feed mixture comprising benzene and at least one other hydrocarbon with an adsorbent capable of selectively adsorbing benzene from the feed mixture.
Claim 3
Dependent Claim
19 words
The method of claim 2 wherein the feed mixture is a refinery process stream in the gasoline boiling range.
Claim 4
Independent Claim
33 words
The method of any preceding claim wherein the adsorbent is a cationic exchanged L, X, Y, or mordenite zeolite, the cation being selected from alkali metals, alkaline earth metals and rare earth metals.
Claim 5
Independent Claim
23 words
The method of any preceding claim wherein the benzene is converted to cyclohexane by hydrogenation in the presence of a hydrogen activation catalyst.
Claim 6
Dependent Claim
25 words
The method of claim 5 wherein the catalyst is supported by the adsorbent either as the sole support material or admixed with another support material.
Claim 7
Dependent Claim
13 words
The method of claim 6 wherein the hydrogen activation catalyst is supported platinum.
Claim 8
Independent Claim
21 words
The method of any preceding claim wherein the desorbent is selected from benzene, toluene, xylene, ethyl benzene, or a mixture thereof.
Claim 9
Independent Claim
26 words
The method of any of claims 2 to 8 wherein the benzene adsorption, conversion to cyclohexane, and cyclohexane desorption are conducted in the same reactor vessel.
Claim 10
Independent Claim
16 words
The method of any of claims 2 to 9 wherein the desorbent is the feed mixture.
