ABSTRACT:
The present invention provides a process for producing aromatic hydrocarbons at a sufficiently high yield, from a light hydrocarbon containing mainly hydrocarbons having 7 or fewer carbon atoms. The process of the present invention comprises bringing a feedstock containing mainly light hydrocarbons having 2 to 7 carbon atoms into contact with a catalyst composition comprising at least a gallium-containing crystalline aluminosilicate wherein a reaction step for converting the feedstock to aromatic hydrocarbons comprises at least two or more reaction layers formed of the catalyst composition, arranged in series and heating means arranged either between or in the reaction layers, the amount of the catalyst in the first stage reaction layer is 30 percent by volume or less of the total catalyst volume, and/or the yield of the aromatics in the product outflowing from the first reaction layer is from 0.5 to 30 percent by mass.
