20130078693 | PROCESSES FOR STARTING UP DEEP TANK ANAEROBIC FERMENTATION REACTORS FOR MAKING OXYGENATED ORGANIC COMPOUND FROM CARBON MONOXIDE AND HYDROGEN - Processes are provided for starting up of anaerobic, deep tank fermentation systems used in the anaerobic bioconversion of hydrogen and carbon monoxide in a gaseous substrate stream to oxygenated organic compounds such as ethanol. In the processes injectors using a motive liquid are used to introduce gas substrate into the deep tank fermentation reactor where at least one of:

20130078688 | LOW ENERGY, HIGH SUBSTRATE EFFICIENCY, ANAEROBIC, DEEP, BUBBLE COLUMN FERMENTATION PROCESSES - Bioconversion processes are disclosed that enable high conversion efficiencies of gas substrate containing both carbon monoxide and hydrogen to oxygenated organic compounds via the carbon monoxide and hydrogen pathways using anaerobic, deep, bubble column fermentation in a cost effective manner. The high conversion efficiency processes of this invention comprise the combination of using at least two deep, bubble column reactors in flow series and using certain feed gas compositions and microbubbles while avoiding carbon monoxide inhibition. | 03-28-2013 |
20130078687 | FROM CARBON MONOXIDE AND HYDROGEN ANAEROBIC FERMENTATION PROCESSES USING A PRE-REACTOR/DEEP TANK REACTOR SYSTEM - Processes are disclosed for the low energy, anaerobic bioconversion of hydrogen and carbon monoxide in a gaseous substrate stream to oxygenated organic compounds such as ethanol by contact with microorganisms in a fermentation system with high conversion efficiency of both hydrogen and carbon monoxide. The processes of this invention use a pre-reactor and a deep, tank reactor in gaseous substrate flow sequence to obtain high conversion of gas substrate without undue risk of carbon monoxide inhibition. | 03-28-2013 |
