Platinum-Promoted Ga/Al sub(2)O sub(3) as Highly Active, Selective, and Stable Catalyst for the Dehydrogenation of Propane
A novel catalyst material for the selective dehydrogenation of propane is presented. The catalyst consists of 1000ppm Pt, 3wt% Ga, and 0.25wt% K supported on alumina. We observed a synergy between Ga and Pt, resulting in a highly active and stable catalyst. Additionally, we propose a bifunctional ac...

Zusammenfassung: | A novel catalyst material for the selective dehydrogenation of propane is presented. The catalyst consists of 1000ppm Pt, 3wt% Ga, and 0.25wt% K supported on alumina. We observed a synergy between Ga and Pt, resulting in a highly active and stable catalyst. Additionally, we propose a bifunctional active phase, in which coordinately unsaturated Ga super(3+) species are the active species and where Pt functions as a promoter. Alkane activation: The selective dehydrogenation of propane is achieved with a catalyst material consisting of 1000ppm Pt, 3wt% Ga, and 0.25wt% K supported on alumina. The synergy between Ga and Pt results in a highly active and stable catalyst. A bifunctional active phase is proposed, in which coordinately unsaturated Ga super(3+) species are the active species and Pt functions as promoter. |
