Abstract In this paper, CaO/bio-char was synthesized by directly co-pyrolysis of Ca(OH)2 and rice straw, and used as catalyst to catalytic pyrolysis of soybean oil to produce high quality biofuel. In this co-pyrolysis process, CaO particles has been successfully embedded on the bio-char surface. During the catalytic pyrolysis process, CaO/bio-char showed a good catalytic performance on the deoxygenation of soybean oil. Pyrolysis temperature affected the pyrolysis reactions and pyrolytic products distributions dramatically, higher pyrolysis temperature lead to seriously cracking reactions, lower bio-oil yield and higher gases yield, and lower pyrolysis temperature lead to higher bio-oil yield with higher oxygenated compounds content… More >
