    摘要: The present invention discloses a process for the synthetic generation of methane from a feed gas mixture comprising carbon monoxide, hydrogen and water vapour and optionally aromatic hydrocarbons; said process comprising the steps of: a) bringing the feed gas mixture in contact with a fluidized bed catalyst having catalyst particles which comprise as catalytic active component a metal and/or a metal compound or a mixture thereof under the circumstances of: b) an elevated temperature in the range of 250 to 500°C; c) a feed gas pressure in the range of 0.8 to 70 bar; d) a gas hourly space velocity of 1000 to 50000 h-1; and e) a concentration of H2/CO in the initial gas mixture in the range of 0.25 to 5. The afore-mentioned process allows to catalytically convert hydrogen and carbon monoxide effectively in a fluidized bed catalytic reactor which avoids a rapid deactivation of the catalyst material and therefore delivers a high activity of the catalytic active components in the process. Both thermochemical reactions, the endothermic reformation of higher hydrocarbons, i.e. aromatic hydrocarbons, and the exothermic methane generation, proceed simultaneously within the fluidized be catalytic reactor, leading to an overall enhanced thermal efficiency of the conversion process.

    摘要: A process for the preparation of methane from gas mixtures containing hydrogen and/or steam and at least 5% by volume of carbonmonoxide by means of a nickel catalyst, which contains on a thermally stable oxidic carrier metallic nickel particles as an active catalyst component, in which the metallic nickel particles are chemically bonded to the thermally stable carrier. The chemical bond between the metallic nickel particles and the carrier is preferably provided by an interfacial layer different from the oxidic carrier, which layer consists of a compound containing oxygen and at feast one member selected from the group consisting of nickel and the carrier base element or elements.
