Influence of some parameters on methyl chloride conversion over various zeolites: h-zsm5 h-zsm12 and mordenite

摘要

We tried to analyse the behaviour and performances of H-ZSM5 in the catalytic conversion of CH_3Cl. After many regenerations, the MFI zeolite affords stable reproductible results in the reaction. The same study led on H-ZSM12 permits to appreciate a different structure effect on the activity and selectivity of products. For that Zeolite, we note brutal decreasing in activity as a function of the time and irreversible falling activity after n Retreatments under air at 500 deg.C.
