| Abstract
| - SSZ-33 is tested for possible application as a hydrocarbon trap by investigating the temperature-programmeddesorption behavior of toluene (used as a probe molecule) and the results are compared to those obtainedwith zeolites β, Y, mordenite, and ZSM-5. SSZ-33 shows higher adsorption capacity than the other zeolitesat the conditions used here, and as well as better hydrothermal stability than zeolite β, and is therefore identifiedas a promising candidate for use as a hydrocarbon trap in cold-start emission control.
