| 摘要 |
The invention relates to a method for producing methane from hydrogen and carbon dioxide for the removing of carbon dioxide and/or hydrogen present in natural gas and for the utilization of hydrogen, which was extracted via electrolysis by means of electricity from renewable energy sources, which method uses a device which already exists, in particular for the storage or distribution of natural gas, for compressing natural gas by a single-stage or multi-stage gas compressor, wherein a catalyzer (7) and, after the catalyzer (7), a dryer (9) are arranged in the gas flow of the compressed natural gas. The already existing gas compressor generates heat during compressing of the natural gas, such that the compressed natural gas already has temperatures in the range between 200°C and 400°C, without supplying external heat, such that according to the invention only a catalyzer (7) and a dryer (9) is required in order to convert the carbon dioxide and the hydrogen to methane and water vapor, and to remove the water vapor from the natural gas. |
