Document Type and Number:

WIPO Patent Application WO/2007/114127

Kind Code:

A1

Abstract:

Disclosed is a method for converting ethylbenzene contained in a C8 aromatic hydrocarbon-mixed raw material into benzene at a high conversion rate. The method comprises contacting a C8 aromatic hydrocarbon-mixed raw material containing ethylbenzene with an acid catalyst having at least one metal selected from the metals belonging to Groups VII and VIII in the periodic table in the presence of H2 to convert the ethylbenzene into benzene. The raw material contains a C9-C10 aromatic hydrocarbon containing ethyltoluene, and the conversion of the ethyltoluene into toluene is achieved simultaneously with the conversion of the ethylbenzene.
