A FLUIDIZED BED SYSTEM FOR REMOVING MULTIPLE POLLUTANTS FROM A FUEL GAS STREAM

摘要

A system includes an adsorber having a fuidized bed of a plurality of adsorption materials. The adsorber is configured to receive the gaseous fuel stream including the plurality of pollutants and adsorb the said plurality of pollutants in a single unit from the gaseous fuel stream to generate a clean gas stream substantially free of the pollutants. Different adsorption materials are designed to remove different pollutants over a similar temperature range. The pollutants include at least one of sulfur compounds, chlorine, ammonia, mercury, arsenic, selenium, cadmium, or combinations thereof.
