Abstract
Gas adsorption studies were carried out for pore analysis of ZSM-5 cat alysts used in n-heptane aromatization, to understand the deactivation behavior of zeolite channels. Results suggested that the alumina bind er protected the zeolite catalyst by accommodating most of the coke. A nalysis of the zeolitic part of the pores indicated that the straight channels are mainly blocked at pore openings and provided an evidence for molecular traffic control mechanism (MTC).
