海泡石的活化及其对植物油脱色性能的研究

Study on Activation of Sepiolite and its Decoloration Properties for the Vegetable Oils

通过对海泡石进行活化处理 ,研究了酸浓度、焙烧温度、焙烧时间、脱色温度及油土比等因素对海泡石吸附脱色性能的影响 ,探讨了海泡石对植物油脱色的最佳条件 ,结果表明 ,海泡石活性土脱色效果优于国产活性白土 。

Treating the sepiolite with activation, the influence factors, such as degree of acidity, calcination temperature, calcination time, soil-oil ratio and decolorization temperature on the sepiolote decolorization properties for the vegetable oil, were investigated.The optimum condition of the sepiolite decolorization were also studied. The results showed that the effect of decolorization on the vegetable oil with treated sepiolite is better than that with other treated clay minerals.
