  • Methods for Abatement of Arsenic and Phosphorous Contaminants From Fuel Gases Prior to Gasification
    Publication number: 20110185899
    Abstract: Methods for abatement of antimony-containing, arsenic-containing and/or phosphorous-containing impurities in fuel gas that is derived from a carbonaceous source can include contacting the fuel gas with an absorbent comprising a capture compound. The capture compound has one or more alkali metals, one or more alkaline earth metals, or a combination of one or more alkali and alkaline earth metals. The fuel gas impurities are reacted with the capture compound, which can be used alone or dispersed on the adsorbent, at a temperature greater than or equal to approximately 300° C. to form solid capture products comprising antimony, arsenic, or phosphorous and the alkali or alkaline earth metal.
