NOVELTY – Bioethanol fermentation involves alcoholic fermenting plant material containing sucrose, glucose or fructose as a raw material derived from plant sources directly or after hydrolysis, by using yeast strains. The yeast is flocculated in tower type fixed bed, fluidized or expanded bioreactors, containing a unit of coupled biocatalysts. Must is prepared and fed in the bioreactors, which are converted to fermented material. The fermented material is degassed and biocatalysts are recovered, which are treated and returned to the biocatalyst fermenter to recover ethanol. USE – Method for fermenting bioethanol for use in industrial production of alcoholic beverages, fuel ethanol, industrial alcohol or anhydrous alcohol.
D16 (Fermentation industry – including fermentation equipment, brewing, yeast production, production of pharmaceuticals and other chemicals by fermentation, microbiology, production of vaccines and antibodies, cell and tissue culture and genetic engineering.); E17 (Other aliphatics.); H06 (Gaseous and liquid fuels – including pollution control. Chemical aspects of catalytic exhaust systems for cars are included as well as liquid or gaseous fuels of non-petroleum origin e.g. methanol or ethanol-based fuels. Combustion improvement additives for liquid fuels are included (C10L).)
