Abstract
A plant includes an adsorber in which a metal is plated onto a non-metallic sacrificial materials from a metal carbonyl at a predetermined temperature. Particularly preferred adsorbers include two sections, wherein a first metal (e.g., nickel) is plated onto graphite in the first section, and wherein a second metal (e.g., iron) is plated onto graphite in the second section.
Claims4
A method of reducing a metal carbonyl concentration in a feed gas, comprising:
- forming the feed gas in a gasification process, wherein the feed gas from the gasification process includes a metal carbonyl;
- heating the feed gas upstream of an absorber in a heater to form a heated feed gas;
- and
- contacting the heated feed gas in an adsorber with a sacrificial non-metallic material at a temperature sufficient to plate a metal from the metal carbonyl onto the sacrificial non-metallic material, wherein the sacrificial non-metallic material comprises graphite.
