Abstract: Implementations of the disclosed subject matter provide a process for producing ethylene glycol from a carbohydrate feed. The process may include contacting, in a reactor under hydrogenation conditions, the carbohydrate feed with a bifunctional catalyst system which may include a heterogeneous hydrogenation catalyst including a magnetically active metal, and a soluble retro-Aldol catalyst including tungstate. A liquid effluent stream may be obtained from the reactor and may include hydrogenation catalyst particles and tungsten oxide precipitate particles. The hydrogenation catalyst particles may be magnetically separated from the tungsten oxide precipitate particles in the liquid effluent stream using a magnet in a separation vessel. The separated hydrogenation catalyst particles may be retained in a separation zone in the separation vessel and may be subsequently removed from the separation zone. A liquid product stream may be obtained from the separation vessel and may include the tungsten oxide precipitate particles and ethylene glycol.

Abstract: Disclosed are a highly efficient neopentyl glycol preparation method and a device therefor. The method includes adding a hydroxypivaldehyde solution and hydrogen to a hydrogenation reactor that includes a hydrogenation catalyst. The hydroxypivaldehyde solution includes 6 to 30% by weight of hydroxypivaldehyde, 35 to 70% by weight of neopentyl glycol, 10 to 30% by weight of alcohol, and 10 to 30% by weight of water.The neopentyl glycol preparation method does not require separate heating in a section of a feed vessel to an inlet of a hydrogenation reactor unlike conventional technologies to save energy, and, at the same time, by-products with a high boiling point are not generated in the section to prevent poisoning of a hydrogenation catalyst in a reactor due to the by-products with a high boiling point and increase a hydrogenation yield, and a device therefor can be provided.

Abstract: The preparation of high-quality oxo process alcohols from inconstant raw material sources is the technically demanding problem which is addressed by a process for continuously preparing an alcohol mixture, in which an input mixture which contains an olefin and has a composition that changes over time is subjected to an oligomerization to obtain an oligomerizate and at least a portion of the olefin oligomers present in the oligomerizate are hydroformylated with carbon monoxide and hydrogen in a hydroformylation in the presence of a homogeneous catalyst system to give aldehydes, at least some of which are converted to the alcohol mixture by subsequent hydrogenation. The process provides a constant plasticizer quality to be produced over a long production period and, optionally, a higher throughput with the same product quality. This is achieved a) by control of the temperature and/or the conversion of the oligomerization as a function of the current composition of the oligomerizate; and b) by control of the composition of the catalyst system and/or of the pressure of the hydroformylation as a function of the current composition of the aldehydes.
