INTEGRATED PROCESS FOR PRODUCING ETHANOL FROM METHANOL
摘要
In one embodiment, the invention is to a process for producing ethanol, the process comprising the steps of carbonylating methanol in a carbonylation system in the presence of a carbonylation catalyst under conditions effective to form acetic acid; hydrogenating the acetic acid in a hydrogenation system in the presence of a hydrogenation catalyst to form a crude ethanol product comprising ethanol and water; separating the ethanol from the water to form an ethanol stream and a water stream; and directing at least a portion of the water stream to the carbonylation system, e.g., for use as an extractant in a permanganate reducing compound removal system.
