Abstract
A method for producing light aromatic hydrocarbons from Caromatic hydrocarbons includes a step of contacting a Caromatic hydrocarbon with a dealkylation catalyst comprising a KL zeolite, and platinum and a modifying metal supported thereon in the presence of hydrogen, to obtain a light aromatic hydrocarbon. The modifying metal is selected from the group consisting of Group IIA metals and rare earth metals. By using a Pt/KL catalyst comprising a specific modifying metal in the dealkylation reaction of Caromatic hydrocarbons for producing light aromatic hydrocarbons, the method shows the advantages of high conversion rate of feedstock, high yield of light aromatic hydrocarbons, good reaction selectivity.
