Abstract

PURPOSE: To enhance decomposability by efficient pretreatment, by bringing a water-contg. cellulosic material into contact with ozone in the biologycal decomposition of a cellulosic material.
CONSTITUTION: Raw materials 5 for a water-contg. cellulosic material supplied from feed tank 4 is brought into countercurrent contact with ozone or a mixt. with another gas supplied through gas-blowing aperture 2 in ozone reactor 1. The raw material 5 is reacted with the ozone by said contact, causing decomposition of lignin in the raw material 5 and desturction of the crystal structure of cellulose. The raw material 5, which went down in a form of travelling belt 3 and was reacted with the rising ozone by said contact, is drawn by discharge feeder 6, and the ozone produced in ozone generator 7, is consumed in the reactor 1 and discharged out of the system.
