Abstract: The ash of Huadian oil shale is made to remove H₂S in this experiment. XRD and nitrogen adsorption experiments are used to analyze the physical and chemical properties of the ash, the results show that the ash of oil shale has many metal and nonmetal oxides, and also has much microporous and mesoporous, all above is helpful to remove H₂S. The sample is modified by different ways to see the change of adsorption capacity. the sample which is modified by alkali and sprinkler is the best adsorbent, but the sample which is modified by microwave does not increase the removal ability obviously.
