    • The invention relates to a process for producing a methane-containing gas from synthesis gas, wherein a synthesis gas containing carbon monoxide and hydrogen is fed for methanation to a reactor system (1) having a catalyst material, wherein the process gas stream leaving the reactor system (1) is divided into a product gas stream and a recycle gas stream, and wherein the recycle gas stream, for compensation of the pressure drop, is transported through an ejector (5) and for cooling is passed together with the synthesis gas into the reactor system (1). According to the invention, the product gas stream is compressed to a pressure which is greater than the pressure of the synthesis gas that is fed to the reactor system (1). Either compressed product gas or industrial gas from an industrial gas pipe system (9) is fed as propellant medium to the ejector (5). The invention also relates to a methane production plant for carrying out the process.
    • 本发明涉及从合成气生产含甲烷气体的方法,其中将含有一氧化碳和氢气的合成气进料到具有催化剂材料的反应器系统(1)中进行甲烷化,其中离开反应器的工艺气流 系统(1)被分成产物气流和再循环气流,其中用于补偿压降的再循环气流通过喷射器(5)输送,并且冷却与合成气一起进入 反应器系统(1)。 根据本发明,产物气流被压缩至大于供给到反应器系统(1)的合成气的压力的压力。 来自工业气体管道系统(9)的压缩产物气体或工业气体作为推进剂介质被供给到喷射器(5)。 本发明还涉及用于进行该方法的甲烷生产设备。
