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 vols. 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 5 lines have same intersection. It is shown that the general law of intersection in gas chromatog. can be applied to the study of deactivated catalysts.
