摘　　要：对碱性物质 /多孔性物质 (M/N型 )负载固体碱吸附胶质性能及再生方法进行了试验研究。研究发现 ,M/N型负载固体碱对汽油胶质具有一定的吸附能力 ,以活化剂汽油溶液 (活化剂含量为 2 0 0 μg/ g)为再生溶剂 ,可有效地对吸附胶质失活后的固体碱进行再生。此外 ,汽油固体碱预碱洗的室内试验表明 ,M /N型负载固体碱预碱洗效果良好 ,可使脱臭装置的使用寿命明显延长 2倍以上。The adsorptive capacity of gasoline gum and the regeneration method of M/N supported solid base are studied experimentally. The result shows that some gum can be removed from naphtha by this kind of supported solid base. After adsorbing gasoline gum, the solid base is deactivated. The deactivated solid base can be effectively regenerated taking active agent\|gasoline as regenerating solvent (the content of active agent in gasoline is 200 μg/g). Pretreating of gasoline by the M/N solid base can greatly prolong the life of sweetening catalyst.
