Abstract
In one aspect, a hydroformylation reaction process comprises contacting an olefin, hydrogen, and CO in the presence of a homogeneous catalyst in a cylindrical reactor to provide a reaction fluid, wherein the reactor has a fixed height, and wherein a total mixing energy of at least 0.5 kW/m3 is delivered to the fluid in the reactor; removing a portion of the reaction fluid from the reactor; and returning at least a portion of the removed reaction fluid to the reactor, wherein the returning reaction fluid is introduced in at least two return locations positioned at a height that is less than 80% of the fixed height, wherein the at least two return locations are positioned above a location in the reactor where hydrogen and carbon monoxide are introduced to the reactor, and wherein at least 15% of the mixing energy is provided by the returning reaction fluid.
