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.

Limiting acetic acid production in ethane ODH process

The product distribution from an oxidative dehydrogenation process can be altered by co-feeding different ratios of ethanol to steam, in the range of 0.01 to 0.50 ethanol:steam to an oxidative dehydrogenation reactor. Increasing the ethanol to steam ratio was found to: increase ethylene yield; decrease acetic acid yield; increase, or decrease, or cause no effect on CO or COyield; and have negligible effect on ethane conversion. The feed ethanol is converted to carbonaceous products without negatively effecting the catalyst activity.

Oxidative dehydrogenation process

Provided in this disclosure is a process for the oxidative dehydrogenation of a lower alkane into a corresponding alkene. The process includes providing a gas stream comprising the lower alkane to a reactor; contacting, in the oxidative dehydrogenation reactor, the lower alkane with a catalyst that includes a mixed metal oxide; and providing to the last 50% of the oxidative dehydrogenation reactor a stream comprising from 0.01 vol. % to 10 vol. % of a C-Calcohol.
