Abstract
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.
