## Abstract

A plant (100) includes a gas turbine (110) that receives a feed gas (130), wherein a metal plates from a metal carbonyl contained in the feed gas onto a sacrificial metal (152A) in an adsorber (150A), and wherein the feed gas in the adsorber has a temperature sufficient for plating the metal onto the sacrificial metal.

## Claims

### Claim 1

A method of reducing a metal carbonyl concentration in a feed gas for a gas turbine, comprising:
providing a feed gas that includes a metal carbonyl;
heating the feed gas upstream of the adsorber to a temperature of about 270° C. to about 330° C.;
contacting the feed gas in an adsorber with a sacrificial metal at a temperature sufficient to plate a metal from the metal carbonyl onto the sacrificial metal, thereby producing a purified feed gas; and
providing the purified feed gas to a gas turbine.

### Claim 2 (depends on 1)

The method of claim 1 wherein at least a portion of the feed gas is produced from gasification of a material selected from the group consisting of petroleum coke, visbreaker bottoms, asphaltenes, and vacuum bottoms.

### Claim 3 (depends on 1)

The method of claim 1 wherein the feed gas comprises syngas.

### Claim 4 (depends on 1)

The method of claim 1 wherein the metal carbonyl is selected from the group consisting of nickel carbonyl, iron carbonyl, and cobalt carbonyl.

### Claim 5 (depends on 1)

The method of claim 1 wherein the sacrificial metal comprises iron.

### Claim 6 (depends on 1)

The method of claim 1 wherein the feed gas is heated by a gas turbine feed gas preheater.

### Claim 7 (depends on 1)

The method of claim 1 wherein the metal from the metal carbonyl is nickel, iron, or cobalt.
