ABSTRACT:
A process for producing aromatic hydrocarbons comprises bringing hydrocarbons having 2 to 12 carbon atoms into contact with a modified crystalline galloaluminosilicate catalyst prepared by treating a crystalline galloaluminosilicate having a tool ratio of SiO.sub.2 /(Ga.sub.2 O.sub.3 +Al.sub.2 O.sub.3) in the range from 5 to 1000 with a sulfur-containing substance. The process of the invention is simple and suited for general application and the catalyst can be prepared at a low cost. Aromatic hydrocarbons can be produced efficiently from the material hydrocarbons by bringing them into contact with the modified galloaluminosilicate having the excellent catalytic activity. The process of the invention can be adopted widely and effectively in the petroleum refining, in the petroleum chemistry and in the chemical industry in general.
