    摘要: 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 reactor 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.

    摘要: An integrated process for making methanol, acetic acid, and a product from an associated process is disclosed. Syngas (120) is produced by combined steam reforming (109) and autothermal reforming (118) of natural gas (102) where a portion (112) of the natural gas bypasses the steam reformer (109) and is blended with the steam reformer effluent for supply to the autothermal reformer (ATR) (118) with C02 recycle (110). A portion of the syngas is fed to C02 removal (122) to obtain the recycle C02 and cold box (130) to obtain a hydrogen stream (131) and a CO stream (135). The remaining syngas, hydrogen stream (131) and C02 from an associated process are fed to methanol synthesis (140), which produces methanol and a purge stream (124) supplied to the C02 removal unit. The methanol is supplied to an acetic acid unit (13)6 with the CO (135) to make acetic acid, which in turn is supplied to a VAM synthesis unit (148). Oxygen for both the ATR and VAM synthesis can be supplied by a common air separation unit (116), and utilities such as steam generation can further integrate the process.
