When producing an aromatic hydrocarbon by a contact reaction of a lower hydrocarbon with a catalyst, the aromatic hydrocarbon is produced stably for a long time while maintaining a high aromatic hydrocarbon yield. In a process for producing an aromatic hydrocarbon by being equipped with a reaction step for obtaining the aromatic hydrocarbon by a contact reaction of a lower hydrocarbon with a catalyst and a regeneration step for regenerating the catalyst used in this reaction step, and by repeating the reaction step and the regeneration step, yield of the aromatic hydrocarbon is calculated at constant intervals of time. A yield as the standard is set up from this calculated yield. Based on the change of yield relative to this standard, the regeneration time of the regeneration step is prolonged. A threshold value is set up in the change of yield. In case that the change of yield of the aromatic hydrocarbon has been lower than the threshold value in the reaction step, the regeneration time of the regeneration step is prolonged.

Method of regenerating lower hydrocarbon aromatizing catalyst

[Task] To improve activity of a lower hydrocarbon aromatization catalyst and the catalyst stability. [Solving Means] In a method for producing a lower hydrocarbon aromatization catalyst to produce an aromatic compound by a catalytic reaction using a lower hydrocarbon as a raw material, the catalyst includes a metallosilicate on which molybdenum is supported, a silane in 0.75 weight % or more relative to the metallosilicate component is supported, and the catalyst is prepared by conducting a compressive shaping without adding an inorganic binder that binds particles of the catalyst. As a result, the lower hydrocarbon aromatization catalyst maintains a sufficient shape-retaining property even by a compressive shaping in a binderless manner. Stability of the catalyst and activity of the catalyst improve by subjecting the lower hydrocarbon aromatization catalyst to a compressive shaping in a binderless manner. Its advantageous effect is conspicuous when the amount of addition in terms of silicon oxide is 0.75 weight %.

It is more preferable to obtain the aromatizing catalyst by loading molybdenum and silver after modifying a zeolite formed of the metallosilicate with a silane compound that has a molecular diameter larger than a pore diameter of the zeolite and that has an amino group, which selectively reacts at a Bronsted acid point of the zeolite, and a straight-chain hydrocarbon group.

A catalyst for producing aromatic compounds from lower hydrocarbons while improving activity life stability of methane conversion rate; benzene formation rate; naphthalene formation rate; and total formation rate of benzene, toluene and xylene is formed by loading molybdenum and copper on metallo-silicate serving as a substrate and then calcining the metallo-silicate. When the catalyst is reacted with a reaction gas containing lower hydrocarbons and carbonic acid gas, aromatic compounds are produced. In order to obtain the catalyst, it is preferable that molybdenum and copper are loaded on zeolite formed of metallo-silicate after the zeolite is treated with a silane compound larger than a pore of the zeolite in diameter and having an amino group and a straight-chain hydrocarbon group, the amino group being able to selectively react with the zeolite at a Bronsted acid point of the zeolite. It is preferable that a loaded amount of molybdenum is within a range of from 2 to 12 wt. % based on total amount of the calcined catalyst while copper is loaded at a copper to molybdenum molar ratio of 0.01 to 0.8.
