:Esterifying acetic acid to produce ester feed for hydrogenolysis
专利权人
:
CELANESE INT CORP [US]
;
Disclosed herein are processes for alcohol production by reducing an esterification product, such as ethyl acetate. The processes comprise esterifying an excess molar ratio of acetic acid with an alcohol, such as ethanol, to produce the esterification product. The esterification product is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising the alcohol, in particular ethanol, which may be separated from the crude reaction mixture.

:
CELANESE INT CORP [US]
;
A hydrogenation catalyst and process using the catalyst for converting a mixture comprising acetic acid and ethyl acetate to ethanol at a first temperature, and the catalyst desorbs ethyl acetate, in the absence of hydrogen, at a second temperature that is greater than the first temperature. The catalyst has a suitable chemisorption of ethyl acetate at the first temperature in the absence of hydrogen. In one embodiment, the first temperature ranges from 125 DEG C to 350 DEG C and the second temp...
