Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
50 words
A process for converting a feedstock comprising aliphatic and/or alicyclic hydrocarbons into aromatic hydrocarbons by bringing a mixture in a fluid phase of said feedstock and an oxidising agent other than molecular oxygen or a gas containing molecular oxygen into contact with a solid acidic catalyst having Bronsted acid sites.
Claim 2
Dependent Claim
50 words
A process for converting a feedstock comprising aliphatic and/or alicyclic hydrocarbons into aromatic hydrocarbons by bringing a mixture in a fluid phase of said feedstock and an oxidising agent other than molecular oxygen or a gas containing molecular oxygen into contact with a solid acidic catalyst having Bronsted acid sites.
Claim 3
Dependent Claim
20 words
A process according to claim 1 wherein the hydrocarbon feedstock is a C 1 -C S aliphatic or alicyclic hydrocarbon.
Claim 4
Dependent Claim
14 words
A process according to claim 2 wherein the feedstock comprises methane, ethane and/or ethylene.
Claim 5
Dependent Claim
32 words
A process according to any one of the preceding claims wherein the solid acidic catalyst with Br6nsted acid sites is an aluminosilicate zeolite with a silica to alumina ratio greater than 12:1.
Claim 6
Dependent Claim
36 words
A process according to claim 4 wherein the zeolite contains a further component or components selected from a gallium compound and a compound of a Group VIII metal according to the Periodic Table due to Mendeleef.
Claim 7
Dependent Claim
15 words
A process according to claim 5 wherein the compounds are the oxides of the metals.
Claim 8
Dependent Claim
41 words
A process according to any one of the preceding claims wherein the oxidising agents other than molecular oxygen or a gas containing molecular oxygen are selected from nitrous oxide, sulphur trioxide, hydrogen peroxide, ozone, nitric oxide, carbon dioxide and nitrogen oxyfluoride.
Claim 9
Dependent Claim
32 words
A process according to any one of the preceding claims wherein the reaction is carried out in the fluid phase in contact with the solid catalyst at temperatures from 10°C to 600°C.
Claim 10
Dependent Claim
25 words
A process according to any one of the preceding claims wherein the reaction is carried out at a pressure of between 1 and 50 bar.
Claim 11
Dependent Claim
29 words
A process according to any one of the preceding claims wherein the relative proportions of the hydrocarbon feedstock to the oxidising agent by volume is between 1:1 and 10:1.
