Abstract: The process disclosed is for the improved reforming of petroleum fractions by catalytic conversion to a mixture of hydrocarbons rich in aromatics. In the process, naphtha fraction is contacted with two types of catalysts (1) a conventional reforming catalyst and (2) an acidic reforming catalyst containing a crystalline iron silicate. Splitting the reformate into two fractions and recycling the same to the two different reaction zones containing the two types of catalysts. The fraction recycled to the acidic reforming catalyst is rich in aromatics.
