Method for producing bio-ethanol in the process of alcoholic fermentation, preferably from renewable raw materials

摘要

the subject of the invention is a way to produce bio ethanol by fermentation from renewable raw materials, such as potatoes, maize, sugar cane, straw, wheat, rice and other biomass, including waste. bio ethanol obtained from this process is used for non consumer products, for example, as a component for the production of biofuels.the method consists of preparing a mash of raw material, water, medium and mikroorganizu00f3w, conversion of sugars contained in the raw material during alcoholic fermentation to product, separation of bio ethanol from the broth gorzelnianego, which is then subjected to anaerobic fermentation, and obtained her dciek is subjected to oxidation and directed to the preparation stage of the mash.method for bio ethanol invention consists of closed circulation process water and their treatment to the effective implementation of the process of alcoholic fermentation after return stream after anaerobic fermentation, and thus, reducing the consumption of water in the process.
