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.
