Abstract: The disclosure provides a system and a process for injecting and uniformly distributing a liquid into a fermentation broth in a bioreactor for maintaining stable condition within the fermentation broth. The system includes a downcomer section which contains two or more circular pipe conduits extending from a wall of the downcomer to the center vertical axis line of the downcomer. Liquid injection apertures are arranged along the circular pipe conduit and are non-uniformly spaced apart from the center vertical axis of the downcomer to the wall of the downcomer. The apertures further alternate and are offset between the top and bottom surfaces of the circular pipe conduit. The process of the disclosure involves using the system described above for carrying out a fermentation process for converting a C1-substrate to at least one product such as ethanol.

Abstract: The invention is directed to a process for producing one or more fermentation product in a multi-stage process including an inoculation reactor and at least one bioreactor. The inoculation reactor is fed a C1-containing gaseous substrate containing a reduced amount of hydrogen. The hydrogen is reduced to increase the proportion of CO in the C1-containing gaseous substrate being provided to the inoculation reactor. The inoculation reactor ferments the CO-rich C1-containing gaseous substrate and produces an inoculum, which is fed to at least one bioreactor. The bioreactor receives the C1-containing gaseous substrate, which may or may not contain reduced amounts of hydrogen, to produce one or more fermentation product. By providing a CO-rich C1-containing gaseous substrate to the inoculation reactor, both the inoculation reactor and the subsequent bioreactor(s), are able to have increased stability and product selectivity.
