Preparation and catalytic evaluation of [Ga]MCM-58 and of MCM-58-type catalysts with different aluminum contents

摘要

The large pore zeolite MCM-58 has been synthesized with nSi/nAl-ratios varying from 15 to35 and also in its new gallosilicate form [Ga]MCM-58 with a nSi/nGa-ratio of 15. The catalyticproperties of these materials were characterized using the disproportionation of ethylbenzeneand the hydroconversion of n-decane as catalytic tests. MCM-58 and Pt-loaded MCM-58,respectively, proved to be highly active catalysts in these reactions.
