  • Patent number: 9029614
    Abstract: Disclosed herein are processes for alcohol production by reducing ethyl acetate produced by hydrogenating acetic acid in the presence of a suitable catalyst. The product of the acetic acid hydrogenation is fed directly to a decanter to separate the hydrogenation product into an aqueous phase comprising water and ethanol and an organic phase comprising ethyl acetate. The organic phase 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. Thus, ethanol may be produced from acetic acid through an ethyl acetate intermediate without an esterification step. This may reduce the recycle of ethanol in the hydrogenolysis process and improve ethanol productivity.

  • Patent number: 8932372
    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.

  • Publication number: 20130211151
    Abstract: The present invention relates to a process for the production of ethanol. The process comprises the step of hydrogenating acetic acid in a hydrogenation reactor in the presence of a catalyst and under conditions effective to form a crude ethanol product. The acetic acid may be obtained from a carbonylation system. The process further comprises the step of separating, in at least one column, at least a portion of the crude ethanol product into a distillate and a residue. The distillate comprises ethanol, water, and ethyl acetate. The residue comprises acetic acid and water. The process preferably comprises the step of directing at least a portion of the residue to at least one column of the carbonylation system. The process further comprises the step of separating the first distillate to form a purified ethanol product.

  • Patent number: 8309757
    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.
