In the present work, adsorptive-catalytic properties of the system based on ZSM-5 zeolite and γ-Al2O3 as a binder were studied. Such system is considered to be used as adsorption trap within vehicle exhaust gas neutralization concept in order to solve so-called “cold start” problem. In aim to study modifying effect of silver on the properties of zeolite, such compositions as Ag/ZSM-5+γ-Al2O3 and HZSM-5+Ag/γ-Al2O3 were prepared. The silver loading was 10 wt.%. The samples were tested in a prompt thermal aging regime. The composition of the reaction mixture was varied to elucidate the effects of CO and hydrocarbons on the state of the active sites.
