Abstract: Processes for producing alcohols such as ethanol and propanol from a mixed acid feedstock in an integrated process. In one embodiment, the process comprises the step of carbonylating methanol in the presence of a carbonylation catalyst to form a mixed acid feedstock comprising acetic acid and one or more higher acids, preferably comprising propionic acid. The mixed acid feed is hydrogenated in the presence of a hydrogenation catalyst to form a crude alcohol product comprising ethanol and one or more higher alcohols, preferably including propanol.

Abstract: The present invention relates to processes for the recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising ethyl acetate, ethanol and acetaldehyde and a residue stream comprising ethanol, acetic acid and water. The ethanol product is recovered from the residue stream. A liquid recycle stream is sent to a second vaporizer to form a second vapor feed stream that is fed to the hydrogenation reactor.

Abstract: This invention provides an integrated two stage economical process for the production of vinyl acetate monomer (VAM) from acetic acid in the vapor phase. First, acetic acid is selectively hydrogenated over a hydrogenating catalyst composition to form ethylene either in a single reactor zone or in a dual rector zone wherein the intermediate hydrogenated products are either dehydrated and/or cracked to form ethylene. In a subsequent second stage so formed ethylene is reacted with molecular oxygen and acetic acid over a suitable catalyst to form VAM. In an embodiment of this invention reaction of acetic acid and hydrogen over a hydrogenation catalyst and subsequent reaction over a dehydration catalyst selectively produces ethylene, which is further mixed with acetic acid and molecular oxygen and reacted over a supported palladium/gold/potassium catalyst.
Abstract translation: 本发明提供了一种用于在蒸气相中从乙酸生产乙酸乙烯酯单体（VAM）的综合两阶段经济方法。 首先，在氢化催化剂组合物中选择氢化乙酸，以在单个反应器区域或双重反应器区域中形成乙烯，其中中间氢化产物被脱水和/或裂化形成乙烯。 在随后的第二阶段中，如此形成的乙烯通过合适的催化剂与分子氧和乙酸反应以形成VAM。 在本发明的一个实施方案中，乙酸和氢气在氢化催化剂上的反应和随后的脱水催化剂反应选择性地产生乙烯，其进一步与乙酸和分子氧混合并在负载的钯/金/钾催化剂上反应。
