    摘要: A wire catalyst for hydrogenation reaction and/or dehydrogenation reaction comprises a metallic core and an oxide surface layer covering at least part of the surface thereof. The metallic core is electrically conductive so that the metallic core itself can generate heat by directly passing an electric current therethrough or electromagnetic induction. The oxide surface layer is made of an oxide of a metallic element constituting the metallic core. The oxide surface layer is provided with a porous structure having pores opening at the surface of the oxide surface layer. The catalytic material is supported in the pores of the oxide surface layer. When a shaped wire catalyst is manufactured, the shaping into a specific shape is made before the oxide surface layer having the porous structure is formed and the catalytic material is supported thereon.

    摘要: 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%. As a pretreatment for a reforming reaction by which aromatic hydrocarbons and hydrogen are formed, the catalyst is increased in temperature and kept at the temperature for a certain period of time while a gas containing methane and hydrogen is supplied thereto.

    摘要: 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.
