Catalytic activity of scandium-zeolite in cumene cracking

ABSTRACT

Scandium exchanged NaX zeolites NaXSc 1-NaXSc 5 are active in cumene cracking. The rate of conversion of cumene increases with increasing the scandium content of the catalyst, the reaction temperature and the activation temperature of the catalyst. The apparent energy of activation is calculated on non-thermally pretreated catalyst to be 84. 43 KJ mol [-1] whereas, on the pre-activated catalyst it is 40. 08 KJ mol[-1]
