<P>PROBLEM TO BE SOLVED: To produce an aromatic hydrocarbon stably for a long time, while maintaining a high aromatic hydrocarbon yield in producing the aromatic hydrocarbon by the catalytic reaction of a lower hydrocarbon with a catalyst. <P>SOLUTION: This method for producing the aromatic hydrocarbon, including a reaction process of obtaining the aromatic hydrocarbon by the catalytic reaction of the lower hydrocarbon with the catalyst and a regeneration process of regenerating the catalyst used in the reaction process, and repeating the reaction process and regeneration process is provided by calculating the yield of the aromatic hydrocarbon at the pass of each and every predetermined time during the reaction process. By setting a yield becoming a standard from the calculated yields, the regeneration time is extended in the regeneration process based on the change of the yield to the standard. Also, by setting a threshold value in the changes of the yields, the regeneration time is extended in the case that the change of the yield of the aromatic hydrocarbon in the reaction process is lower than the threshold value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
