The Study of Process of Alternative Fuel Production from Renewable Raw Materials

AbstractThe objective of the research was to study the process of biofuels production from raw materials of plant origin such as wastes of food and agricultural industry. The process includes a stage of enzymatic degradation of plant polysaccharides. The proposed method allows to produce ecologically friendly renewable biofuels and to provide partial utilization of carbohydrate-containing industrial wastes or by-products. The economic efficacy of alcohol production is increased due to the yield growth as a result of the optimization of the microbiological synthesis process.The disadvantages of existing methods of biofuel production are usage of food crops as raw materials, high labour and financial costs incurred during planting, harvesting, handling and storage of such crops and a small yield of the final product. The proposed method of biofuel production is based on the usage of non-edible raw materials of plant origin such as wastes and by-products of isolation of protein preparations from lupin seeds. The bioconversion of polysaccharide complex of feedstock to soluble carbohydrates is carried out using a composition of hydrolytic enzymes with cellulase activity of at least 3500 units gram 1 and xylanase activity of at least 2500 units gram-1. The liquid biobutanol is produced by fermentation of carbohydrate substrate obtained as a waste or a by-product after processing of raw materials with bacteria Clostridium beijerinckii
