Abstract
In a process for the synthetic generation of methane from a feed gas mixture, a feed gas mixture including carbon monoxide, hydrogen, water vapor, CO, volatile hydrocarbons comprising Cand higher, unsaturated Ccomponents and aromatic hydrocarbons in the range of 1 to 10 vol % is provided. The feed gas mixture is contacted with a fluidized bed catalyst having catalyst particles having a catalytic active component selected from the group consisting of a metal, a metal compound and combinations thereof. The contacting occurs at an elevated temperature in the range of 250 to 450° C., a feed gas pressure in the range of 0.8 to 70 bar, a gas hourly space velocity of 1000 to 50000 h, and a concentration of H/CO in the gas mixture in the range of 0.25 to 5.
