| 摘要 |
The invention relates to a methanation reactor (10) for reacting hydrogen with a carbon-based compound and producing methane, comprising: a hollow body (105) designed to receive a fluidised bed and comprising an inlet (110) for the carbon-based compound; an outlet (115) for methane and water produced by a methanation reaction; a heat exchanger (120) extending at least partially through the hollow body and at least partially submerged in the fluidised bed; and a means (127) for introducing overheated water vapour into the heat exchanger. In certain embodiments, the reactor comprises, downstream of the part of the heat exchanger that extends through the hollow body, a means for cooling the overheated vapour, designed to saturate the overheated vapour. |
