(79c) Bio-Ethylene from Gas Fermentation:  Gas Treatment Challenges and Successes

As consumers look for sustainable products, sustainably produced ethylene will become an important intermediate chemical. Ethylene is a building block that can be used to produce consumer products such as sustainable aviation fuel, polyethylene, surfactants, and PET fibers. “Green” ethanol can be dehydrated to ethylene using various commercial technologies. “Green” ethanol can be produced using many sustainable processes. One technology which has been commercialized is gas fermentation of industrial waste gases. These industrial waste gases contain many trace components that can impact fermentation. The unique challenges and novel solutions around mitigation of the fermentation inhibitors present in a variety of industrial waste gas fermentation feedstocks will be discussed.
