    Abstract: 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.

    Abstract: Provided is a process for producing an aromatic hydrocarbon using a molybdenum-containing solid catalyst, more specifically a process for producing an aromatic hydrocarbon efficiently from a lower hydrocarbon gas essentially containing methane by activating the molybdenum-containing solid catalyst with maintaining a high yield for a long period of time.The process comprises a pre-contacting step of allowing a molybdenum-containing solid catalyst to contact with a pre-contacting gas comprising at least one selected from a lower hydrocarbon and a hydrogen gas; and a reaction step of allowing the pre-contacted catalyst to contact with a raw material gas essentially containing methane, to generate an aromatic hydrocarbon, wherein the starting temperature in the pre-contacting step is lower than the reaction temperature, and the temperature during the pre-contacting step from the beginning to the end is not over the reaction temperature.

    Abstract: A process for producing an aromatic hydrocarbon, comprises heating the hydrocarbon in the presence of a catalyst carrying a molybdenum compound or a rhenium compound on a metallosilicate carrier modified with a silicon compound, a sodium compound or a calcium compound. The silicon compound is a silane compound having a basic group selected from amino, alkylamino and pyridyl groups and an organic group of a size equal to or greater than the pore size of the metallosilicate and selected from trialkoxy and triphenyl groups and the sodium compound or the calcium compound is a compound having an organic group of a size equal to or greater than the pore size of the metallosilicate and selected from crown ether, hexafluoropentanedione and acetylacetonate. The silane compound, the sodium compound or the calcium compound is modified so as to make an oxide thereof by impregnating the metallosilicate carrier with it and subsequently heat-treating it in an oxygen-containing atmosphere.
