摘　　要：为提高秸秆蒸汽爆破预处理制乙醇的酶解率及经济效益,研究了蒸汽爆破预处理过程中影响酶解效果的物料温度、喷爆出口直径、汽爆次数等因素,以寻找提高酶解效率的方法。试验结果显示,物料温度对酶解效果有显著影响,在不破坏纤维素结构且不产生酶解抑制物的前提下,温度越高越有利于水解;在不致堵塞喷爆口的前提下,喷爆出口直径越小酶解效果越好;汽爆次数对于酶解物料预处理效果有着显著的积极影响。To increace the enzymatic hydrolyzation and the economic benefit during the process of staw steam blasting for ethanol. The effect of material temperature, outlet diameter, steam blasting times on enzymatic were investigated. The way of increasing enzymatic hydrolyzation was found.The eco- nomic pretreatment parameters are optimised in the current condition of enzymes, according to this therory. The impact of material temperature on the enzymatic effect was remarkable. It was more con- ducive for hydrolysis with higher temperature when the fiber structure was not destroyed and does not produce enzymatic Inhibitor.; the smaller outlet diameter was, the better enzymatic effect got without being blocked. The effect of stream explosive numbers on the pretreatment had a significant impact.
