AlMCM- 48 showed high activity and shape selectivity to the isopropylation of naphthalene. Grafting aluminum on MCM- 48 improved its acidity. It was found that with the increasing of Al content, the performance of AlMCM- 48 catalysts for naphthalene conversion was enhanced. High naphthalene conversion of 89.5％ was achieved over AlMCM- 48 with Si/Al=5.3 under the reaction conditions:n(isopropanol) /n(naphthalene)=2, temperature T=250℃ , time t=4 h.展开更多
