Conclusions
-
1.
The adsorption heats of benzene and cyclohexane on zeolites NaY and CaY were measured at 30°.
-
2.
At all degrees of filling, the adsorption heat of benzene on both zeolites is greater than for cyclo hexane.
-
3.
Replacing Na+ by Ca++ leads to an increase in the initial adsorption heats of both hydrocarbons.
-
4.
A substantial increase in the adsorption heat is observed for cyclohexane as the adsorption volume fills up.
