METHOD FOR CONTROLLING UNDESIRABLE BYPRODUCTS FORMATION CAUSED BY CONTAMINATING ORGANISMS IN THE PRODUCTION OF ETHANOL FROM SYNGAS

摘要

A method of operating a fermentation zone for the production of ethanol from syngas uses a crotonate-like compound to prevent or reverse the effects of butyrogen contamination. The crotonate-like compound works in continuous fermentation processes to reduce or eliminate contamination from butyrate and butanol in the syngas derived ethanol product.
