Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
46 words
A process for reforming alcohols to synthesis gas comprising contacting an alcohol in the absence of steam with the catalyst comprising a carbide of a metal selected from iron, cobalt, manganese and mixtures thereof, at a reaction temperature of about 200° C. to about 600° C.
Claim 2
Dependent Claim
46 words
A process for reforming alcohols to synthesis gas comprising contacting an alcohol in the absence of steam with the catalyst comprising a carbide of a metal selected from iron, cobalt, manganese and mixtures thereof, at a reaction temperature of about 200° C. to about 600° C.
Claim 3
Dependent Claim
27 words
A process as in claim 1 wherein said alcohol is selected from saturated and unsaturated, monohydric or polyhydric alcohols having from 1 to about 6 carbon atoms.
Claim 4
Dependent Claim
11 words
A process as in claim 1 wherein said alcohol is methanol.
Claim 5
Dependent Claim
11 words
A process as in claim 1 wherein said alcohol is ethanol.
Claim 6
Dependent Claim
12 words
A process as in claim 1 wherein said catalyst is iron carbide.

A process as in claim 1 wherein said catalyst is cobalt carbide.
Claim 8
Dependent Claim
12 words
A process as in claim 1 wherein said catalyst is manganese carbide.
Claim 9
Dependent Claim
19 words
A process as in claim 1 wherein said reaction temperature is between about 300° C. to about 500° C.
Claim 10
Dependent Claim
15 words
A process as in claim 1 wherein said reforming is conducted at about atmospheric pressure.
Claim 11
Dependent Claim
22 words
A process as in claim 1 wherein said reforming is conducted at a reaction pressure of about 1 to about 300 atmospheres.
Claim 12
Dependent Claim
18 words
A process as in claim 1 wherein said alcohol is a by-product of a synthesis gas upgrading reaction.
Claim 13
Dependent Claim
17 words
A process as in claim 1 wherein the synthesis gas resulting from the reforming reaction is combusted.
Claim 14
Dependent Claim
19 words
A process as in claim 1 wherein said alcohol reforming is carried out in the absence of co-fed hydrogen.
Claim 15
Dependent Claim
13 words
A process as in claim 1 wherein oxygen is co-fed with the alcohol.
Claim 16
Dependent Claim
46 words
A process for reforming methanol to obtain predominantly hydrogen and carbon monoxide comprising contacting methanol in the vapor phase at a reaction temperature of about 200° C. to about 600° C. with a catalyst comprising a carbide of a metal selected from iron, cobalt, and manganese.
Claim 17
Dependent Claim
46 words
A process for reforming methanol to obtain predominantly hydrogen and carbon monoxide comprising contacting methanol in the vapor phase at a reaction temperature of about 200° C. to about 600° C. with a catalyst comprising a carbide of a metal selected from iron, cobalt, and manganese.
