VERFAHREN ZUM AROMATISIEREN VON PARAFFINEN

摘要

A process for producing aromatic compounds from a paraffin containing feedstock in which the feedstock is passed to a reaction zone into contact with a multi-component catalyst system. The catalyst system comprises a discreet physical mixture of a silicalite homologation catalyst and a metal or metal oxide dehydrogenation catalyst. The process is carried out to cause the dehydrogenation of paraffins to olefins, the oligomerization of olefins to cyclic napthenes and the aromatization of the napthenes. Reaction conditions and relative catalyst concentrations to provide a relationship between the thermodynamic constraint for the dehydrogenation of the paraffins and the balancing of the kinetics of the dehydrogenation and oligomerization reactions to limit the olefin concentration to a value which does not result in substantial coking of the catalyst system.
