摘要: Abstract In this work, co-feeding ethanol with methanol was adopted to prolong the lifetime of a catalyst in propylene (MTP) reaction. The effect an additive on MTP reaction further investigated over catalyst, pure catalysts ZSM-5 and γ-Al2O3, mixed by using alone. catalytic performance showed that increasing addition ethanol, commercial greatly improved, selectivity for ethylene correspondingly increased. performances different reactivity were following order: > γ-Al2O3 γ-Al2O3. Moreover, coke deposition moderately strong acid sites pore blockage responsible deactivation.
