Ultrasonic Cavitation Influence on Mechanical Molecules Activation during Bioethanol Obtaining from Micro Powder Cellulose

The paper presents a model of mechanical molecules activation during bioethanol obtaining from micro powder cellulose under ultrasonic cavitation influence. The process is considered as surface chemical reaction "liquid-solid" of enzymatic hydrolysis which is accelerating by ultrasonic cavitation. Firstly, the model takes into account limitation of each cavitation zone size and cavitation zone size dependency on frequency. In finish, the model allows to evaluate modes, providing maximum rate of bioethanol obtaining from cellulose micro powder.
