摘要
以生物油为原料,在常压和空气氛围下进行非催化部分氧化气化实验制备合成气,考察了气化温度、氧油比对合成气形成特性及合成气品质的影响,并对生物油非催化部分氧化气化制备合成气的主要反应过程进行了讨论。结果表明,升高温度可以促进生物油经非催化部分氧化气化制合成气过程中相关转化反应的进行,合适的氧油比有利于合成气的增加。当温度为1 050℃,空气量为0.2 L/min,进料量为72 g/h时,生物油经部分氧化产生的气体中H2含量最高,CH4、CO和CO2很少;H2/CO和H2/(CO+CO2)均达到最大值,分别为4.3和3.2。
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.
