摘要：
This invention disclosure reported here a supported metal hydroxide adsorbent and a method for its preparation as well as a method for its oxidative regeneration. The supported metal hydroxide adsorbent comprises metal hydroxide and support with a mass ratio of 5-30:100. The adsorbent disclosed in present invention exhibited outstanding adsorption capacity and high selectivity to sulfur impurity in gasoline. The method of oxidative regeneration provides an efficient way for the recovery of the saturated adsorbent.
