Crude rubber seed oil is a potential source for biofuel production. However it contains undesirable impurities such as peroxides and high oxidative components that not only affect the oil stability, colour and shelf-life but promote insoluble gums formation with time that could cause deposition in the combustion engines. Therefore to overcome these problems the crude rubber seed oil is refined by undergoing degumming and bleaching process. The effect of bleaching earth dosage (15-40 wt %), phosphoric acid dosage (0.5-1.0 wt %) and reaction time (20-40 min) were studied over the reduction of the peroxide value in a refined crude rubber seed oil. The analysis of variance shows that bleaching earth dosage was the most influencing factor followed by reaction time and phosphoric acid dosage. A minimum peroxide value of 0.1 milliequivalents/gram was achieved under optimized conditions of 40 wt % of bleaching earth dosage, 1.0 wt % of phosphoric acid dosage and 20 min of reaction time using Response Surface Methodology design.
天然橡胶籽油是生物燃料生产的潜在来源。然而，它含有不希望有的杂质，如过氧化物和高氧化成分，这些杂质不仅影响油的稳定性、颜色和保质期，而且随着时间的推移会促进不溶性胶的形成，从而导致在发动机中沉积。因此，为了克服这些问题，天然橡胶籽油通过脱胶和漂白工艺进行精炼。研究了漂白土用量（15-40wt%）、磷酸用量（0.5-1.0wt%）和反应时间（20-40min）对精制天然橡胶籽油中过氧化物值降低的影响。方差分析表明，漂白土用量是最具影响的因素，其次是反应时间和磷酸用量。在响应面方法设计的优化条件下，即漂白土用量 40wt%、磷酸用量 1.0wt%和反应时间 20min 下，可达到过氧化物值的最小值 0.1 毫当量/克。
