摘要： Integrated processes are provided for syngas refining and bioconversion of syngas to oxygenated organic compound. In the integrated processes ammonia contained in the syngas is recovered and used as a source of nitrogen and water for the fermentation. The integrated processes first remove tars from syngas by scrubbing using a first aqueous medium under conditions that ammonium bicarbonate is unstable. With tars removed, contact between the syngas and a second aqueous medium enables ammonia and carbon dioxide to be removed from the syngas without undue removal of components adverse to the fermentation, processing or oxygenated product such as benzene, toluene, xylene, ethylene, acetylene, and hydrogen cyanide. At least a portion of the second aqueous medium is supplied as a source of water and ammonia for the fermentation.

摘要： 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.

摘要： The methods are utilized to recover ammonium from waste water using CO2 acidified absorption water. The process is particularly suited for utilization of cellular matter and a CO2 rich tail gas from a syngas fermentation process and derives significant benefit from the recovery of ammonium bicarbonate and ammonium carbonate. Ammonia and ammonium are recovered from the treatment of the syngas as an ammonium rich solution, at least a portion of which is recycled to the fermentation zone to aid in the production of liquid products. A carbon dioxide rich gas produced by fermentation is used to capture the ammonia and ammonium, forming the ammonium rich solution.

摘要： A process converts a gas input stream comprising CO, CO2, and H2 by contact with fermentation liquid into a liquid product that controls the concentration of CO and CO2 in the fermentation vessel. The process charges the feed gas stream and a recycle gas stream to the fermentation vessel and an off-gas stream collects above the fermentation liquid. The off-gas stream flows to a gas injector that uses a recycle liquid as the motive fluid to mix the off-gas with the recycle liquid into a gas-liquid dispersion. Contact of the recycle liquid with the off-gas absorbs CO2 to provide the recycle stream. A gas separation vessel separates the remainder of the off-gas into the recycle gas. Mixing the recycle gas with the gas input stream dilutes the concentration of CO to lower the CO concentration in the fermentation vessel. Separated recycle liquid flows to a CO2 stripper for removal of CO2.

摘要： A moving bed bioreactor (MBBR) produces liquid products from a gaseous substrate of CO and/or CO2/H2 using a biomass that grows on the surface of carrier suspended in a fermentation broth into which the gaseous substrate is at least partially dissolved. The injection devices include gas spargers and preferably a high efficiency gas transfer process such as jet or slot aerator/gas transfer devices. The gas injection device introduces the gas in the form of microbubbles in a substantially horizontal directions that creates eddy currents in the surrounding liquid for thoroughly mixing the fermentation broth in a fermentation vessel. Gas bubbles from the gas delivery device rise through the liquid surface and provide additional mixing and gas dissolution. The motion of gas and liquid keeps the biomass carrier moving can also provide sufficient shear so as to maintain the biofilm thickness on the biomass carrier media in the desirable range. The result of combining a MBBR process for gaseous components of CO and/or CO2/H2 with a highly efficient gas transfer process results in an economical and high product volumetric production rate process for producing liquid fuels such as ethanol.
