Abstract

Form liquid product stream that has a C 13 to C 20 hydrocarbon content of less than 5.0 wt % based upon a total weight of the liquid product stream via a process that includes contacting synthesis gas with a sulfurized Zeolite Socony Mobil-5 catalyst. The sulfurized Zeolite Socony Mobil-5 catalyst can include ZSM-5, cobalt, an alkali metal, sulfur, and a reduction promoter.

First claim

What is claimed:

1. A process for producing a liquid product stream that has a C 13 to C 20 hydrocarbon content of less than 5.0 wt % based upon a total weight of the liquid product stream, the process comprising:
contacting synthesis gas with a sulfurized Zeolite Socony Mobil-5 catalyst, wherein the sulfurized Zeolite Socony Mobil-5 catalyst includes cobalt and a sulfur doped Zeolite Socony Mobil-5 support, with the sulfur being incorporated via sulfate ions, the cobalt being present in an amount within a range of from 1 to 25 wt % based upon a dry weight of the sulfurized Zeolite Socony Mobil-5 catalyst, the sulfur being present in an amount within a range of from 0.01 to 1.00 wt %, based upon a dry weight of the sulfurized Zeolite Socony Mobil-5 catalyst, the conditions consisting essentially of a temperature within a range of from 150 to 300° C., a pressure within a range of from 5 to 40 bar, and a gas hourly space velocity within a range of from 100 to 10000 h −1 .

2. The process of claim 1 , wherein the sulfurized Zeolite Socony Mobil-5 catalyst includes an alkali metal.

3. The process of claim 2 , wherein the alkali metal is within a range of from 0.01 to 4.50 wt % based upon a dry weight of the sulfurized ZSM-5 catalyst.

4. The process of claim 2 , wherein the alkali metal is sodium.

5. The process of claim 1 , wherein the sulfurized Zeolite Socony Mobil-5 catalyst includes a reduction promoter.

6. The process of claim 5 , wherein the reduction promoter is within a range of from 0.01 to 5.00% based upon a dry weight of the sulfurized ZSM-5 catalyst.

7. The process of claim 6 , wherein the reduction promoter is ruthenium.

8. The process of claim 1 , wherein the liquid product stream has a C 5 -C 12 hydrocarbon content of at least 25 wt % based upon a total weight of the liquid product stream.
