Abstract: Improved catalysts for dehydrogenation can be prepared by coprecipitating the metal containing catalysts from a solution of metal ions in the presence of a high molecular weight polyhydric material such as potato starch. The result of having the polyhydric material present is that the precipitate has the form of a gelatinous precipitate of improved processability. The catalyst itself is more active in dehydrogenations and physically stronger than comparable catalyst prepared by conventional methods.

Abstract: IMPROVED OXIDATIVE DEHYDROGENATION CATALYST CAN BE PREPARED BY ADDING RHENIUM OR A PLATINUM GROUP METAL TO A METAL FERRITE OXIDATIVE DEHYDROGENATION CATALYST, FOR EXAMPLE BY ADDING 0.02% PALLADIUM TO MG FERRITE TREATED WITH 2% PHOSPHORIC ACID, THE CONVERSION, SELECTIVITY AND YIELD WERE THE SAME AS UN UNPROMOTED MG FERRITE TREATED WITH 3% PHOSPHORIC ACID BUT AT SUBSTANTIALLY LOWER INLET AND MAXIMUM TEMPERATURES. IN OTHER EMBODIMENTS OF THE INVENTION THE YIELD CAN BE SUBSTANTIALLY INCREASED WHILE REDUCING THE TEMPERATURES, E.G., MG FERRITES+5% H3PO4+0.01% PD GAVE 67 MOLE PERCENT YIELD OF BUTADIENE AT A MAXIMUM TEMPERATURE 40*F. LOWER THAN THE UNPROMOTED CATALYST WHICH GAVE ONLY 60 MOLE PERCENT YIELD.
