Abstract
A process of producing a fluid bed oxacylation catalyst for olefins and diolefins having the following formula Pd-M-A where M=Au, Cd, Bi, Cu, Mn, Fe, Co, Ce, U and mixtures thereof, A=an alkali metal or mixture thereof, and M is present in the range of from 0 to 5 wt %, comprising milling a fixed bed oxacylation catalyst precursor comprising Pd-M on a fixed support with a fluid bed catalyst aqueous binder material to form a uniform aqueous slurry, drying the aqueous slurry to remove the water to form microspheroidal particles of solid fluid bed catalyst precursor, impregnating the microspheroidal particles with a solution of alkali metal salt to form the fluid bed catalyst. The catalyst is particularly useful in the manufacture of vinyl acetate from ethylene, acetic acid and oxygen.
