ABSTRACT:
A system and method are disclosed for removing hydrocarbons from a gaseous mixture, which comprises selecting a plurality of agents which are effective for adsorbing hydrocarbons at predetermined temperatures, wherein for at least two of the adsorbing agents, the temperatures at which the maximum adsorption rates for the hydrocarbons occur, are different from one another, and contacting the adsorbing agents with the gaseous mixture at the predetermined temperatures to cause adsorption of the hydrocarbons. A multistage catalyst system for converting NO.sub.x, CO, and hydrocarbons from a gaseous mixture to innocuous products is disclosed, which comprises the above described system for removing hydrocarbons as one stage, and a main body catalyst stage for converting NO.sub.x, CO, and hydrocarbons to innocuous products, wherein the gaseous mixture passes from one stage to the other.
