摘要： A process for producing aromatic hydrocarbon by bringing a low-boiling hydrocarbon feedstock containing olefin and/or paraffin into contact with a zeolite catalyst in a fixed-bed adiabatic reactor provided with a fixed catalyst bed containing a zeolite catalyst, characterized by conducting a catalytic cyclization under the following conditions: (1) the zeolite catalyst has an initial catalytic activity of at least 0.2 sec in terms of the initial first-order reaction rate constant of cracking of n-hexane therewith; (2) the temperature of the catalyst bed ranges from 450 to 650 DEG C; (3) the catalyst bed has a temperature distribution along the length thereof from the inlet to the outlet, and the distribution has at least one peak; and (4) the outlet temperature of the catalyst bed is in the range of the inlet temperature +/- 40 DEG C. The process permits aromatic hydrocarbon to be produced in a high yield and the operation to be conducted safely for long while avoiding the reduction in catalyst activity.
