The conversion of methanol over zeolite H‐T was investigated in a fixed bed reactor. H‐T was prepared from Na‐T by ion exchange with HCl and NH 4 Cl solutions. The HCl solution caused appreciable dealumination. High yields of ethene were obtained with NH 4 Cl exchangeed zeolites Na‐T with 45% decationization, high proprne yields with low HCl or NH 4 Cl Exchanged catalysts. Low methanol partial pressures and short residence times favoured the formation of lower olefins. Lowest coking rates were observed at a reaction temperature of 693 K. The catalytic activity decrased slowly with the number of reaction/regeneration cycles. The distribution of procucts > C 2 could be described by the most probable distribution of Schulz and Flory.
