Chromium catalyst material and methods of making and using same |
| abstract |
The present disclosure relates to methods of making chromium-containing dehydrogenation catalysts using chromium feedstocks that do not need to include chromium (VI). The present disclosure also relates to catalysts produced thereby, and dehydrogenation methods using such catalysts. In one aspect of the present disclosure, a method comprises: providing a shapeable mixture comprising, on a dry basis: aluminum hydroxide present in an amount ranging from about 40% to about 90% by weight; an acid (such as nitric acid), present in an amount ranging from about 2% to about 15% by weight; and a source of chromium (III), present in an amount ranging from about 2% to about 35% by weight; shaping the shaped mixture; and calcining the shaped mixture. In certain embodiments, the method further includes impregnating the calcined mixture with an aqueous impregnating solution comprising a chromium (III) salt; and calcining the impregnated mixture. |
