Rare earth element containing catalysts for dehydrogenating paraffins and the methods of making the catalysts are disclosed. A rare earth modified alumina support in eta-alumina form, theta-alumina form, or combinations thereof is impregnated with chromium-containing solution. The chromium-impregnated support is then subjected to calcination processes. The produced catalyst contains the rare earth element, chromium, and alumina. The crush strength of the produced catalyst is greater than 0.4 daN/mm.

Catalyst for paraffin dehydrogenation

A method for the dehydrogenation of lower alkanes is disclosed. The method employs a chromium-alumina dehydrogenation catalyst with high chromium content supported on eta-alumina. The catalyst contains greater than 25 percent by weight chromium in the form of chromium (III) oxide, and exhibits extended stability over traditional alkane dehydrogenation catalysts.
