Abstract
Medium pore, ZSM-5 zeolite was subjected to chemical vapour deposition to alter its pore opening size. The extent of alteration and its effe ct on shape selectivity during toluene ethylation has been investigate d. The time on stream behaviour of the pore size altered zeolite showe d a deactivating trend with enhancement in hours on stream. The stabil ization of the alkylation activity of the catalyst has been achieved b y controlled coking and the details are discussed.
