  • Publication number: 20230303484
    Abstract: A process for producing dinitrile comprises supplying a C6 organic compound, an oxidizing agent, ammonia and a diluent to a reaction zone to produce a reaction mixture and contacting the reaction mixture in the reaction zone with a heterogeneous catalyst at a temperature from 50 to 200° C. to convert at least a portion of the C6 organic compound to dinitrile and water and produce a reaction effluent. At least part of the reaction effluent is supplied to a separation system to separate at least dinitrile and unreacted ammonia from the reaction effluent and additional water is supplied to a portion of the reaction effluent prior to or during separation of unreacted ammonia from the reaction effluent.

  • Patent number: 11512276
    Abstract: The present disclosure provides methods for controlling oxygen concentration during aerobic biosynthesis, e.g., fermentation. The method may comprise feeding an oxygen-containing gas into a vessel including a fermentation feedstock and reacting the fermentation feedstock with the oxygen-containing gas to form a broth including a gaseous phase dispersed within the broth. The gaseous phase may comprise any unreacted oxygen from the oxygen-containing gas. The method further includes reducing the concentration of the unreacted oxygen in the dispersed gaseous phase to less than the limiting oxygen concentration (“LOC”) for flammability before separating the gaseous phase from the fermentation broth. The concentration of the unreacted oxygen in the gaseous phase is reduced by employing oxygen removal schemes or oxygen dilution schemes.

  • Publication number: 20190316072
    Abstract: Provided herein are systems and methods for recycling and supplementing off-gas from a gas fed reaction process. The systems and methods are particularly useful for bioprocesses that convert hydrogen gas into one or more biosynthetic products. By maintaining separate hydrogen and oxygen feed gas streams, and forming a recycle gas that introduces a target component of the supply gas to the bioreactor within a target concentration range, the yields, productivities, and safety profiles of the bioprocess can be enhanced.
