摘要：
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.
