Title: PROCESSES AND CONTROL SYSTEMS FOR HIGH EFFICIENCY ANAEROBIC CONVERSION OF HYDROGEN AND CARBON OXIDES TO ALCOHOLS
Abstract:
High conversion efficiency processes are disclosed for the anaerobic bioconversion of syngas to alcohol. The processes use bioreactors that have a non-uniform gas composition and a substantially uniform liquid composition such as deep tank bioreactors. By maintaining certain electron to carbon mole ratios in the syngas feed to the bioreactors and certain partial pressures of carbon dioxide in the off gas from the bioreactors, at least about 80 percent of the hydrogen and at least about 95 percent of the carbon monoxide in the feed can be consumed.
