NOVELTY - Green fuel production system from biomass comprises a catalytic cracking reactor (C) for generating water vapor, water-soluble substances and gaseous oil and sludge by decomposing at least two raw materials with biomass and solid waste fuel contained in a raw material inlet (A); a gas-liquid separator I (E) for separating by condensing gas and liquid substances generated from the catalytic cracking reactor; a deoxygenation catalyst reactor (G) for generating paraffin hydrocarbon by adding hydrogen to the liquid material separated from the gas-liquid separator 1; a gas-liquid separator II (H).    USE - The system is useful for generating waste oil or refuse derived fuel (claimed).    ADVANTAGE - The system provides waste resource utilization to produce high quality waste oil, efficiently utilizes energy and improves air quality by reducing greenhouse gases (carbon dioxide) emissions.
