Abstract: A process for producing aromatic hydrocarbons and hydrogen, in which a lower hydrocarbons-containing feedstock gas is reformed by being supplied to and being brought into contact with a catalyst under high temperature conditions thereby forming aromatic hydrocarbons and hydrogen. The method includes the steps of (a) supplying a hydrogen gas together with the feedstock gas during a supply of the feedstock gas; and (b) suspending the supply of the feedstock gas for a certain period of time while keeping a condition of a supply of the hydrogen gas. The catalyst is exemplified by a metallo-silicate carrying molybdenum and a metallo-silicate carrying molybdenum and rhodium. An amount of the hydrogen gas supplied together with the feedstock gas is set to be preferably larger than 2% and smaller than 10%, more preferably within a range of from 4 to 8%, much more preferably 8%.

Abstract: An aromatic compound, particularly benzene, is stably produced in the presence of a catalyst from a lower hydrocarbon having 2 or more carbon atoms, particularly from an ethane-containing gas composition such as ethane gas and natural gas. Disclosed is a process for producing an aromatic compound by reacting ethane or an ethane-containing raw gas in the presence of a catalyst. The catalyst may comprise molybdenum carried on metallosilicate such as H-type ZSM-5H or H-type MCM-22. In the reaction, the temperature is from 550 to 750° C., preferably not lower than 600° C. and not higher than 680° C. Additionally, the raw gas further contains methane and hydrogen is added thereto, thereby improving the production efficiency and stability.
