稻壳生物质油是由复杂的有机化合物和水组成的，其氧化稳定性直接影响其物理化学性质和应用。分别在空气流动和氧气流动条件下进行了高级氧化实验。通过测定氧化前后pH值的变化和沉淀物的重量，研究了气体流量、氧化时间、温度和铜箔4个因素对稻壳生物质油氧化过程的影响。结果表明，生物质油的pH值随气体流量的增加和运行时间的延长而缓慢下降。油中铜的存在使氧化后的沉淀物重量增加。通过对氧化前后生物质油组成的GC-MS分析，发现氧化后的生物质油中以醋酸为主，这是由于氧化后生物质油的pH值降低所致。同时，酚类化合物的含量也较氧化前有所增加。提出了一种基于链式反应的生物质氧化机理。
The rice husk-based biomass-oil is composed of complex organic compounds and water, and its oxidation stability has a direct influence on its physico-chemical property and application. The advanced oxidation experiments were carried out through the flowing of air and oxygen respectively. The influences of four factors, including gas flux, oxidation time, temperature and copper foil, on the oxidation process of rice husk-based biomass-oil, by measuring the pH value variation and the weight of deposit before and after oxidation were studied. The results showed that the pH value of biomass-oil decreased slowly with the increases of the gas flux and operation time. The presence of copper in the oil made the sediment weight increase after oxidation. Based on the GC-MS analyses of the compositions of biomass-oil before and after oxidation, it was found that the acetic acid was the main component in the oxidised biomass-oil, which was attributed to the pH value decrease of biomass-oil after oxidation. At the same time the content of phenolic compound was also increased compared with that before oxidation. It was also proposed a chain-reaction-based mechanism for the biomass oxidation.
