Claim 0:
1. A device used to carry out biological fermentation processes in a production facility comprising:
a multiple-pass trickle bed reactor for production of alcohols, acids and/or metabolic by-products, based on the biological fermentation of gases generated by industrial processes or the gasification of organic materials, the multiple-pass trickle bed reactor comprising multiple vessels with at least one vessel having at least one section, and further wherein the sections of the reactor include a first section and a second section separated by a liquid-gas barrier and wherein the sections are arranged sequentially,
a liquid recirculation circuit that removes liquid fermentation broth from a bottom of the reactor and supplies the fermentation broth to a top of the reactor to be flowed back through the reactor, and
a first gas recirculation circuit that recirculates gases within the first section and a second gas recirculation circuit that recirculates gases within the second section, wherein the first gas recirculation circuit and the second gas recirculation circuit each provides gas recirculation flow rates that range from 2× to 10× a volumetric flow of gases supplied to the reactor.
