摘要: To reduce acetal concentrations when separating ethanol from a crude product in one or more distillation column, at least one of the columns is operated at a higher pressure to increase the equilibrium constant that favors hydrolysis of the acetal. The crude product may comprise ethanol, acetaldehyde, water and one or more acetals, such as diethyl acetal. The acetal concentration may be reduced thus reducing the need to separate acetal from the crude product.
摘要翻译: 为了减少在一个或多个蒸馏塔中从粗产物中分离乙醇时的乙缩醛浓度,至少一个塔在较高的压力下运行以增加有利于缩醛水解的平衡常数。 粗产物可以包括乙醇,乙醛,水和一种或多种缩醛,例如二乙缩醛。 缩醛浓度可能会降低,从而减少了从粗产物分离乙缩醛的需要。

摘要: A process is described for producing an alcohol product, in which (a) a first feed composition comprising acetic acid is converted to a product comprising acetone; and (b) a second feed composition comprising at least part of the acetone produced in (a) is hydrogenated in the presence of a catalyst to produce a hydrogenation effluent comprising isopropanol.

摘要: Purifying and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol mixture are employed to allow recovery of ethanol and remove impurities. In particular, light ends are separated in an acetaldehyde removal column operating at a pressure greater than atmospheric pressure to recover acetaldehyde that may be returned to the reactor and reduce acetaldehyde concentrations in an ethyl acetate stream.

摘要: A process for purifying ethanol by using a finishing reactor to remove impurities, such as ethyl acetate, acetaldehyde, acetic acid, and diethyl acetal, present in ethanol after distilling a crude product from a hydrogenation reactor. The finishing reactor may reduce the impurities in the presence of hydrogen and a catalyst or may hydrolyze the impurities.
