Supported catalyst, for an aldol condensation column, has one or more metal oxides as active components to give an increased catalyst activity

摘要

The supported catalyst has one or more metal oxides as active components on a carrier for aldol condensation. The catalyst carrier is gamma -aluminum oxide. The active components include one or more oxides of rare earth metals. The concentration of the active components is 5-12 wt.% of the catalyst carrier weight. The active component is preferably yttrium oxide or praseodymium oxide. The condensation column packing (1) is composed of packing sheets (2) with straight kinks (5) forming angled kink surfaces (6). Catalyst particles (4) fill the space (3) between neighboring sheets.
