Integrated process for providing raw materials to a downstream operation to generate an article of manufacture. A carbon black production process is integrated with a gas fermentation process, and a feedstock preparation process is integrated with gas fermentation process. Both carbon black and a gas fermentation product are provided to a downstream operation. Secondary products from the carbon black process may be used in the gas fermentation process. Byproducts from the feedstock preparation process may be provided to the downstream operation or may be passed to the carbon black process. In certain aspects, the fermentation product may be ethanol, isoprene, butane diol, and/or ethylene. In certain aspects, the byproduct may be metal, metal oxide, char, silica, and/or steel. In certain aspects, the secondary product may be hydrogen and/or carbon dioxide. The downstream operation may be to generate plastic products, rubber products, tires, textiles, clothes, and the like.

Integrated gas fermentation and carbon black processes

Integrated process for providing multiple raw materials to a downstream operation to generate an article of manufacture. Pyrolysis, torrefaction, reforming, partial oxidation, and/or gasification is integrated with gas fermentation. Integrated process converts carbon sources that would otherwise be vented to the atmosphere or discarded as waste to a fermentation product and one or more byproducts, which in turn are provided to a downstream operation to generate an article of manufacture. In certain aspects, the fermentation product may be ethanol, isoprene, butane diol, ethylene. In certain aspects, the byproduct may be metal, metal oxide, char, silica, and or steel. The downstream operation to generate an article of manufacture may be an operation to generate plastic products, rubber products, textiles, clothes, and the like.

Integrated gas fermentation

The invention provides a process for producing a fermentable gas stream from a gas source that contains one or more constituent which may be harmful to the fermentation process. To produce the fermentable gas stream, the gas stream is passed through a specifically ordered series of removal modules. The removal modules remove and/or convert various constituents found in the gas stream which may have harmful effects on downstream removal modules and/or inhibitory effects on downstream gas fermenting microorganisms. At least a portion of the fermentable gas stream is preferably capable of being passed to a bioreactor, which contains gas fermenting microorganisms, without inhibiting the fermentation process.
