Abstract: The present disclosure relates to limiting the production of acetic acid in an oxidative dehydrogenation process to convert ethane to ethylene. The process of oxidative dehydrogenation includes feeding acetic acid, along with ethane and oxygen into an oxidative dehydrogenation reactor where contact with a catalyst leads to conversion of the ethane into ethylene and acetic acid. By including acetic acid in the feed, the amount of acetic acid produced may be limited and the ratio of ethylene produced to ethane consumed may increase.

Abstract: A system and method for oxidative dehydrogenation including a first reactor having a first ODH catalyst to dehydrogenate an alkane to a corresponding alkene at a first temperature and facilitate generation of steam, a second reactor having a second ODH catalyst to dehydrogenate alkane in a first-reactor effluent to the corresponding alkene at a second temperature that may be greater than the first temperature and facilitate generation of steam, and a third reactor having a third ODH catalyst to dehydrogenate alkane in a second-reactor effluent to the corresponding alkene at a third temperature that may be greater than the first temperature or the second temperature and facilitate generation of steam.

Abstract: A method that includes (a) providing a stream containing ethane and oxygen to an ODH reactor; (b) converting a portion of the ethane to ethylene and acetic acid in the ODH reactor to provide a stream containing ethane, ethylene, acetic acid, oxygen and carbon monoxide; (c) separating a portion of the acetic acid from the stream to provide an acetic acid stream and a stream containing ethane, ethylene, oxygen and carbon monoxide; (d) providing the stream to a CO Oxidation Reactor containing a catalyst that includes a group 11 metal to convert carbon monoxide to carbon dioxide and reacting acetylene to produce a stream containing ethane, ethylene and carbon dioxide; and (e) providing a portion of the stream and a portion of the acetic acid stream to a third reactor containing a catalyst that includes a metal selected from group 10 and group 11 metals to produce vinyl acetate.
