ABSTRACT:
The present invention relates to a composition comprising at least one zeolite consisting essentially of the zeolites selected from the group of neutral and basic zeolites and at least one platinum group metal component. This composition has been found to be useful in a method of treating gas streams comprising hydrocarbons comprising the steps of adsorbing the hydrocarbons on the recited zeolites at a low adsorption temperature range, releasing the hydrocarbons from the zeolite at a high release temperature range and oxidizing the hydrocarbons.
