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

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.
