Hb-zeolite 촉매상에서 Toluene의 불균등화 반응
Shape Selective Disproportionation of Toluene over various Hβ-zeolite Catalyst
In this study, the catalytic activity of Hβ-zeolite was examined in the disproportionation of toluene. The catalytic activity and selectivity to p-xylene for the disproportionation of toluene was dependent on the reaction temperature, the type of impregmented ion and the amount of impregmented ion, the type of carrier gas and the time on stream. P2O5 loaded Hβ-zeolite showed the higher para-selectivity as compared to pure Hβ-zeolite. This phenomenon may be interpreted in terms of shape selectivity arising from the partial blocking of pore or acidity modification.
