Abstract: The present invention relates to hydroformylation reaction processes. In one aspect, a hydroformylation reaction process comprises (a) contacting an olefin, hydrogen, and carbon monoxide in the presence of a homogeneous catalyst in a reactor to provide a reaction fluid, wherein the reactor comprises one or more reaction zones; (b) removing a portion of the reaction fluid from a first reaction zone; (c) passing at least a portion of the removed reaction fluid through a shear mixing apparatus to produce bubbles in the portion of the removed reaction fluid, wherein at least a portion of hydrogen and carbon monoxide provided to the reactor is introduced through the shear mixing apparatus; and (d) returning the removed reaction fluid to the first reaction zone through one or more nozzles wherein the returning reaction fluid exiting each nozzle is a jet, wherein the mixing energy density provided to the reactor by the jets is greater than or equal to 500 Watts/m3.

Abstract: The present invention generally relates to processes for the recovery of rhodium from a catalyst purge stream from a C6 or higher olefin hydroformylation process.

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.

Abstract: The present invention relate to processes for converting olefins to alcohols, ethers, or combinations thereof that are suitable for use as a gasoline additive. In one embodiment, the process comprises (a) receiving a feed stream, wherein the feed stream comprises one or more olefins having 2 to 5 carbon atoms in an amount of up to 80% by weight based on the weight of the feed stream; (b) hydroformylating the feed stream in the presence of a catalyst to convert at least 80% of the olefins from the feed stream to oxygenates; (c) separating a product stream from step (b) into an oxygenate stream and a stream comprising unreacted olefins, inerts, the catalyst, and the remaining oxygenates; and (d) treating the oxygenate stream to convert a plurality of the oxygenates into at least one of an alcohol, an ether, or combinations thereof is suitable for use as a gasoline additive.

Abstract: A thigh supporting pillow includes a thigh sleeve, a wedge-shaped pillow, and one or more attachments for securing the pillow to the sleeve. The sleeve may be a continuous band or a sheet that may be rolled around a thigh. The pillow may be a foam pillow, inflatable pillow or a pillow slip encasing supportive filler material (e.g., down, polyester, buckwheat or plastic particles). The wedge shaped pillow fits between a wearer's crotch and thigh without reaching the knees. The pillow maintains proper alignment of the hips while side-sleeping.
