A process for preparing a catalyst, and catalysts prepared thereby. The process includes selecting a catalyst support and mixing it with one or more chromium containing compounds oxidizable to a Cr+6 state or already in a Cr+6 state, and with one or more transition metal catalyst component, and calcining the catalyst support while oxidizing any chromium containing compound to a Cr+6 state, and spray drying the catalyst support to form catalyst particles. The catalyst supports are characterized by a surface area greater than 50 m2/gram and a pore volume greater than 0.5 cc/gram at the time of mixing the catalyst support with the chromium containing compound. |
