Abstract:
Described herein are catalyst systems and methods of treating emissions that can passively heat aftertreatment catalysts. Also described herein are methods of making such catalyst systems. Aftertreatment catalyst systems can include a catalyst support structure having a surface region on which a criteria-pollutant-treating catalyst and a sorbent exist. Non-limiting examples of sorbents can include those based on MgO, MgO—NaCO 3  double salts, or dolomite. The sorbent can include a eutectic promotor that facilitates exothermic CO 2  adsorption from the exhaust to the sorbent at a first temperature below the light-off temperature of the catalyst. Heat from formation of an exotherm between CO 2  and components of the sorbent is passively transferred to the criteria-pollutant-treating catalyst to increase the surface-region (i.e., catalyst bed) temperature to a value greater than or equal to the light-off temperature, thereby lowering the apparent light-off temperature.

Claim (Index 14):
The aftertreatment catalyst of  claim 10 , wherein the eutectic promotor comprises a mixture of salts selected from the group consisting of NaNO 3 , LiNO 3 , KNO 3 , Ca(NO 3 ) 2 , Mg(NO 3 ) 2 , NaNO 2 , LiNO 2 , KNO 2 , and Ca(NO 2 ) 2 .
