Procedure

An iron containing ZSM-5 catalyst was prepared by the following method: about 10 g of the same HZSM-5 as that of Example 1 was heated in a stream of dry air to 375° C. for 4 hours and then was cooled to room temperature. A solution of 0.3331 g of ferrocene (dicyclopentadienyliron) in 30 g dry toluene was then added to the dried zeolite and the slurry was mixed at room temperature overnight. The slurry was filtered and washed once with 100 ml of Tetralin® to remove excess ferrocene from the external surface of the zeolite. Excess Tetralin® was allowed to evaporate at room temperature to give a Tetralin®/ferrocene wetted zeolite. The recovered solid was then calcined in a stream of dry air at about 538° C. for about 6 hours to produce the desired iron containing catalyst, Catalyst C. The iron loading of this catalyst is about 0.66 wt. %.
