中文摘要：

近些年，有关碱金属对焦炭溶损反应的催化作用已进行了较深入细致的研究，对碱金属以外的金属对焦炭溶损反应的催化作用也引起人们的关注，并取得了一些结果，然而对锌的研究大多是停留在其对耐火材料的侵蚀和结瘤等几个方面的研究，忽视了锌对焦炭溶损反应的催化作用而造成的焦炭粉化等情况。通过气相吸附法制备吸附不同锌含量的焦炭试样，并对吸附锌的焦炭的强度进行检测，得出如下结论：锌的吸附不会对焦炭的强度造成影响；吸附不同锌量的焦样的反应性都会随着锌量的增加而有不同程度的增加，反应后强度随着锌量的增加而降低；锌对焦炭强度产生影响的原因是锌促进焦炭的溶损反应，锌并不会因为吸附到焦炭上而直接对其强度产生明显影响。

英文摘要：

In recent years, the catalysis effect of alkali metal on coke loss reaction has made a further and careful in- vestigation, and the catalysis effect of other minerals on coke solution loss reaction is also a cause for concern. But, researches of zinc are mostly in its stay to the erosion of and warts of refractory material on the way. The damage for the catalysis effect of zinc on the coke loss reaction are ignored. The coke samples were prepared by air adsorption method with different zinc content, their strength was measured. The results show that the strength of coke will not be affected by zinc adsorption quantity. The coke reactivity with different zinc content will increase in some degree and coke strength after reaction will decrease with increase in zinc content of coke. Zinc is a catalyst for loss reaction of coke to promote the solution loss reaction, Zn will not directly impact on its strength.
