以石油渣油制备的活性炭对模拟燃油的脱硫性能研究

Preparation of Porous Carbons from Oil Residues and Eliminating Sulfur from Simulant Fuel

以石油渣油为原料,采取化学活化法和类模板法制备了活性炭材料,并将其用于模拟燃油的吸附脱硫研究。采用高效液相色谱仪分析测量了模拟汽油中的硫含量。结果表明,与以类模板法制备的活性炭相比,以石油渣油为原料通过化学活化法制备的活性炭因微孔丰富和微孔孔容大,对模拟燃油中的含硫化合物二苯并噻吩具有更大的吸附容量和更高的脱硫率。

Porous carbons were prepared from oil residues by NaOH activation and template-like methods re spectively. Their removal capacity for dibenzothiophene from silulant fuel were studied. The sulfur content was characterized by high performance liquid chromatography. The results show that comparing to the template-like porous carbon, the NaOH activated porous carbon has remarkable adsorption capacity and higher removal rate of dibenzothiophene due to its abundant micro-pores.
