Abstract: A method is provided for conversion of heavy alkylaromatic compounds, particularly those in the C8-C12 range, into more valuable aromatics of benzene, toluene and xylene utilizing a toluene disproportionation unit containing a nickel, palladium or platinum-modified mordenite catalyst. The method allows large amounts of these heavy alkylaromatic compounds to be processed without adversely affecting catalyst activity or catalyst life. This is accomplished by introducing the heavy alkylaromatic compounds into the reactor at constant reaction severity conditions and maintaining those conditions during conversion.

Abstract: Disclosed is a method for extending the life of dehydrogenation catalysts used to prepare vinyl aromatic hydrocarbons. The catalysts, which typically include both iron oxide and potassium containing catalysis promoter, are exposed to additional potassium delivered using a potassium carboxylate. The potassium carboxylates are desirably free of halogens and other catalysts poisons or groups that could result in the undesirable properties in vinyl aromatic hydrocarbons produced therewith. The present invention is particularly useful with the production of styrene and methyl styrene.
