bleaching clay

The present paper introduced mainly several methods of recovering oil fr bleaching clay.

本文主要介绍了回收废白土中油脂的几种方法.

With the raw material of spent bleaching clay of oil refining, the regenerated technology was studied.

以油脂生产中的脱色废白土为原料, 制备再生白土.

The results show that the best condition are: 100℃ , 20 minutes , bleaching clay 5 %, active carbon 2 %.

确定最佳吸附脱色条件为: 100℃、20min 、 活性炭添加量为油重的2%, 活性白土添加量为油重的5%.

The oil decoloration rate of regenerated bleaching clay could reach 98.2 % in the optimum operation conditions.

在此条件下再生白土脱色率最好,可达到98.2%.

To make good use of used bleaching clay and increase the benefits, the recovery technology and factors of oil in used bleaching clay that produced in the process of oil bleaching were studied by use of a new-style "three-stage lixiviate reactor" that designed by ourselves.

为了更好地利用废白土增加效益，利用自行设计的一种新型三段式浸出器，对油脂脱色废白土中油脂的回收工艺及影响因素进行了研究。
