| 摘 要： | 取T12系列12种炭基催化剂,采用物理吸附仪测定其比表面积和孔径分布,并在相同条件下做脱硫实验测得硫容。对其比表面积、孔径与SO2吸附分子直径比值与脱硫效果的关系进行研究。结果表明:对于T12系列炭基催化剂,催化效果会随着比表面积和孔径的增加而变得更好,总比表面积超过720m2/g,孔径超过0.85nm以后,催化剂的脱硫效果反而降低。

| Abstract: | Twelve kinds of activated carbon catalyst were measured by physical adsorption instrument,and then the sulfur capacity of these catalysts were measured under the same conditions.The relationship between total surface area,adsorption,diameter ratio between adsorption and SO2 molecular were studied in this paper.The results showed that,when the total surface area was no more than 720m2/g,the average pore size was less than 0.85nm,the desulfurization effect of catalysts increased,on the contrary,the desulfurization effect decreased when these sized surpassed this range. |
