摘要: Abstract The catalytic behaviour of a series mordenites and offretites with varying aluminium content origin has been analyzed for the alkylation benzene toluene by ethanol disproportionation as function their Al molar fraction (m=Al/Al+Si). For both reactions, activity, expressed on per-weight basis, passes through maximum m=0.1 mordenite m=0.12 offretite. As m decreases, amount coke deposited during reaction but deactivation rate increases. Alkylation reactions using reagent are characterized long stable lifetimes catalysts. main influence was found to be ethylbenzene selectivity, which reached 70–90%
