METHOD FOR PRODUCING BIOFUEL USING PYROLYSIS OF TIMBER MATERIAL AND BIOFUEL THEREOF

摘要

PURPOSE: A manufacturing method of biofuel including bio-oil, bio-gas, and bio-char from wood through pyrolysis is provided. CONSTITUTION: A wood raw material is put into a pyrolysis apparatus, and thermally decomposed. The pyrolysis is performed under the following condition. A nitrogen gas is injected at a flow rate of 80 to 120 ml/min, and a pressure is maintained at 0.08 to 0.12 MPa. A temperature initially started at 20 to 25°C and is increased to a final temperature of 300 to 500°C at a rate of 6 to 9°C/min. The final temperature is maintained for 20 to 60 minutes. The wood is oak or bamboo. A mixed biofuel is prepared by centrifuging bio-oil, filtering, and mixing with ethanol.
