Abstract:
1. A system for the production of acetaldehyde, the system comprising; a pump for pressurizing a vessel having an aqueous solution; a gas inlet positioned on the vessel, for introducing dispersible oxidant gas bubbles into the pressurized aqueous solution; a high shear device, having an inlet and an outlet, wherein the inlet fluidly connected to the vessel and the gas inlet, the high shear device for forming a dispersion of the oxidant gas bubbles in the pressurized aqueous solution, wherein the dispersion has an average gas bubble diameter of less than about 5 μm; and a reactor fluidly connected to the high shear device outlet, comprising a composite catalyst for the redox reaction of ethylene to acetaldehyde.
