Abstract
Reaction mechnism of catalytic decomposition of p-Cymene by activ-ated clay was studied and decomposition degree with the change of reaction temp-erature and space velocity was measured.Beside the main dealkylation reaction, dehydrogenation and demethanation reaction were occured as side reaction.Changes of amount of toluol and propylene obtained by dealkylation of p-cymene were nearly parallel with temperature change and space velocity change, and the dealkylation ability of catalyst could be compare by the quantity of propylene approximately.
