Process for Producing Acetic Acid and/or Ethanol By Methane Oxidation

摘要

The process relates to producing acetic acid and/or ethanol from methane. Oxidative coupling of methane (OCM) may produce a mixture of ethane and ethylene that is further oxidized to acetic acid. The ethylene may be hydrated to form ethanol. In addition, the acetic acid may be hydrogenated to produce ethanol.

主权项

1. A process for making acetic acid, comprising:
contacting a methane-containing gas and an oxygen-containing gas in a first reactor with a first catalyst for oxidatively coupling methane to form an effluent comprising ethane and ethylene; and oxidizing at least a portion of the effluent in a second reactor with a second catalyst to form a crude product stream comprising acetic acid.
