Abstract
[Object] To produce aromatic hydrocarbon stably for a long time maintaining a high aromatic hydrocarbon yield when the aromatic hydrocarbon is produced upon making a contact reaction between lower hydrocarbon and a catalyst.[Solving Means] In a method of producing aromatic hydrocarbon, including repeating a reaction step for obtaining aromatic hydrocarbon upon making a contact reaction between lower hydrocarbon and a catalyst and a regeneration step for regenerating the catalyst used in the reaction step, carbon dioxide in an amount of 0.33 to 1.6% by volume relative to an amount of the lower hydrocarbon is added to the lower hydrocarbon, in the reaction step.
