Abstract:
1. A method of converting C9+ alkylaromatic hydrocarbons to BTX (benzene-toluene-xylene), comprising the steps of: reducing a multiple zeolite catalyst with hydrogen gas at 400° C., the multiple zeolite catalyst consisting of: contacting a feed consisting essentially of C9+ alkylaromatic hydrocarbons with the reduced multiple zeolite catalyst and hydrogen in a transalkylation zone of a reactor at a pressure between 1.0 to 3.0 MPa, a temperature of 300° C. to 500° C., a space velocity of 1.0 to 5.0 hr stripping C5 and lighter hydrocarbons and stripping unreacted feed from the effluent; and collecting BTX product from the effluent.
