| abstract |
The present invention relates to a method of producing aromatic hydrocarbons efficiently from hydrocarbons containing C₆-C₈ paraffins, C₆-C₈ olefins or C₆-C₈ naphthenes, wherein L-type zeolite catalyst carrying platinum is filled in reaction tubes of an externally heated tubular reactor in which heat is provided to the reaction tubes externally through a heating medium, and a feedstock containing C₆-C₈ paraffins, C₆-C₈ olefins or C₆-C₈ naphthenes is charged into the reaction tubes to make contact with the catalyst in the presence of hydrogen. |
