色谱交点在失活催化剂研究中的应用 Ⅰ.苯-催化裂化衰化系列催化剂体系

The Application of Gas Chromatographic Intersections in the Study of Deactivated CatalystsⅠ. The System of Benzene-Deactivated Cracking Catalysts

测定了苯在五种积炭量不同的催化裂化衰化系列催化剂上的保留体积,发现它们的logV_g对1/T直线有一共同交点。这是吸附色谱中同一吸附剂上吸附质为同系物时存在色谱交点的延伸。这是将色谱交点规律应用于失活催化剂研究的新探索。

The retention volumes of benzene are measured on five cracking catalysts with different contents of coke deposit, and the five lines of log V_g-1/T are obtained. It is found that the five lines have same intersection. It is shown that the general law of intersection in gas chromatography can be applied to the study of deactivated calatysts.
