【摘要】 为了减少润滑油白土精制过程中的白土用量并提高脱氮能力，开发了一种酸性助剂，用于润滑油白土精制．在相同的反应条件下，考察了酸性助剂对白土精致的影响． 结果表明：酸性助剂增强了白土的脱氮能力，当 ｗ（ 酸性助剂）为０ ．２５ ％ 时，白土脱氮能力提高１ ～２ 倍；当 ｗ（ 酸性助剂） 为０ ．３５ ％ 时，脱氮能力提高２ ～３ 倍． 当达到相同的脱氮率时，白土的质量分数可以减少２ ％ ～３ ％ ， 降低了润滑油精制成本．更多还原

【Abstract】 An acid additive is used in clay treating process to reduce the volume of clay and improve the capacity of denitrogen. At the same conditions, the denitrogen capacity of clay is increased. The capacity improves 1～2 times when w (acid additives)=0.25%;while acid additive is 0.35%, the capacity rises 2～3 times. At the same efficiency of denitrogen, it may reduce the volume of clay by 2%～3%, thus reducing the cost of process.更多还原
