“…after the combustion step, carried out at a sufficiently high temperature in the vicinity of 1000 • C to ascertain that all coke components and all structural water have been completely removed. 11 In a completely different approach by Enterman and van Leuven [145], the oxygen consumed during the combustion of the coke on the catalyst is determined. 12, which is adapted from Refs.…”

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 HC1 and NH4Cl solutions. The HCl solutions caused appreciable dealumination. High yields of ethene were obtained with NH,Cl exchanged zeolites Na-T with 45 % decationization, high propene yields with low HC1 or NH4C1 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 decreased slowly with the number of reactiontregeneration cycles. The distribution of products > C, could be described by the most probable distribution of Schulz and Flory.
