Background technology
Whole world fossil resource growing tension, demand for fuel is constantly increased in China and reduction of greenhouse gas discharge pressure increases day by day, has forced people to develop renewable energy source.Natural cellulosic feedstocks is a renewable resources the abundantest on the earth, and wherein the overwhelming majority all is not used.The cellulosic material of China is also very abundant, and only to produce residuum annual just up to more than 1,000,000,000 tons for farming and forestry, therefore, it is changed into liquid fuel such as ethanol, butanols and Chemicals through biochemical method and has broad prospects.
In order to improve the economy of production technique of liquid fuel, extensively adopt the method that improves concentration of substrate in the enzymolysis process in the world.Through improving the concentration of substrate of cellulosic material in the enzymolysis process, the production concentration after sugared concentration after the hydrolysis and the fermentation all can have a distinct increment.Because the cellulase hydrolysis of high concentration of substrate not only can improve cellulase and usage ratio of equipment, can reduce equipment scale simultaneously, the energy expenditure when the reduction product concentrates is so this technology has great effect to control export of capital and production cost.If but the initial solids content during cellulase hydrolysis is higher than 15%; Whole reaction system exists with wet solid materials form basically, and denseness is high, and at this moment material stirs the very difficulty that becomes; Serious mass transfer and heat transfer problem appear; Greatly reduce enzyme digestion reaction speed, be unfavorable for that enzyme digestion reaction carries out, and accelerate enzymolysis speed, raising enzymatic hydrolyzation particularly important.Accelerate enzyme reaction speed, strengthen reaction process; Through the batch feeding enzymolysis process is the one side that solves this difficult problem; On the other hand; Owing to enzymolysis process have the cycle long, the enzyme consumption is high, the enzyme molecule is sheared reasons such as inactivation easily because of stirring in enzyme reactor, the selection of reactor drum and design also are key factors, the way that therefore improves enzymolysis initial substrate concentration has proposed new requirement to the design of enzymolysis reactor; New-type enzymolysis reactor must improve the mixing efficiency of raw material under lower watt consumption, the Mierocrystalline cellulose enzyme-to-substrate is contacted fully and carry out catalytic hydrolysis reaction.
