Analysis of methods of microbiological processing of molasses for obtaining alternative fuels
Modern studies of foreign scientists in the field of alternative fuels - ethanol, hydrogen and methane from molasses are considered. Based on the analysis of publications it was found that the maximum ethanol content in the mixture - 60 g/l can be achieved in flow reactors. Hydrogen production, which depends on the microorganisms used and is 1-12 mol H2/mol of the saccharide used, is currently unprofitable. Different methods - membrane filtration, elektrofenton, the addition of bentonite of calcium and sodium is proposed for decolorizing molasses wastewater and production companies after its processing. The greatest effect of bleaching the molasses is achieved by membrane filtration and elektrofenton - up to 88%, processing by bentonite allows for maximum bleaching effect 29-39% reduce in turbidity of wastewater by 98%.
