Preparation of syngas from partial oxidation of bio-oil

The production of syngas from partial oxidation of bio-oil under atmospheric air was investigated. The effects of temperature and the ratio of oxygen to bio-oil on the quality of syngas were examined. The reaction mechanism of the process was discussed. The results show that raising temperature can promote the production of syngas from bio-oil by non-catalytic partial oxidation. The appropriate ratio of oxygen to bio-oil is beneficial to enhance the effective components of syngas. When the temperature reaches to 1 050℃, air flow is 0.2 L/min and feed rate is 72 g/h, the contents of H₂ is the highest and that of CH₄, CO and CO₂ is very low. Both H₂/CO and H₂/(CO+CO₂) value reached the maximum.
