    摘要： Process for the conversion of hydrocarbons to ethanol and optionally acetic acid by converting hydrocarbon in a syngas reactor into a stream A comprising a mixture of carbon oxide(s) and hydrogen preferably having a H2/CO molar ratio between 1.5 and 2.5, converting at least part of stream A in the presence of a particulate catalyst in a reactor under a temperature between 150 and 400° C. and a pressure of 5 to 200 bar, into a C2-oxygenates stream B, where stream B includes water, alkanes, ethanol, acetaldehyde, ethyl acetate and acetic acid, which together represent least 80% by weight of the products obtained from the C2-oxygenates conversion reactor. The C2-oxygenates stream B is separated into a stream C comprising H2, CO, CO2 and alkanes, and a stream D including 15 to 40 wt % of acetic acid, 10 to 40 wt % of acetaldehyde and 15 to 40 wt % of ethanol. At least part of stream D is hydrogenated in a hydrogenation reactor into an ethanol stream E, and stream E is subjected to a separating step, followed by recovery of ethanol.

    摘要： This invention relates to a process for the production of lower aliphatic esters by reacting a lower olefin with a saturated lower aliphatic mono-carboxylic acid in the vapor phase in the presence of a heteropolyacid catalyst characterized in that an amount of water in the range from 1-10 mole % based on the total of the olefin, aliphatic mono-carboxylic acid and water is added to the reaction mixture during the reaction. The presence of water enhances the yield of the desired ester. The reaction mixture may optionally contain a di-ether to minimize the by-products.The process is particularly suitable for producing ethyl acetate from ethylene and acetic acid in the presence of water.
