Unmodified bulk alumina as an efficient catalyst for propane dehydrogenation

A series of unmodified bulk Al 2 O 3 materials show an intrinsic activity for selectively catalyzing propane dehydrogenation. The Lewis acid site arising from the unsaturated Al III site in the Al 2 O 3 structure is the active site for the catalytic cycle. The γ-Al 2 O 3 -200 catalyst shows the high...

Summary:A series of unmodified bulk Al 2 O 3 materials show an intrinsic activity for selectively catalyzing propane dehydrogenation. The Lewis acid site arising from the unsaturated Al III site in the Al 2 O 3 structure is the active site for the catalytic cycle. The γ-Al 2 O 3 -200 catalyst shows the highest yield, which delivers an initial conversion of 48% and selectivity of 83%. A series of unmodified bulk Al 2 O 3 materials show an intrinsic activity for selectively catalyzing propane dehydrogenation.
