| 摘要 |
The invention relates to chemistry, in particular to the production of substitute natural gas (SNG). A process for substitute natural gas production from fresh raw synthesis gas comprises reaction stages of fresh synthesis gas (11) in section (10) of methanation, consisting of adiabatic reactors (101-104), sequentially coupled, wherein fresh synthesis gas is supplied in parallel to the mentioned adiabatic reactors, and recycle stage of the part (22) of reaction gas from the first reactor (101) as input gas into the first reactor. The invention allows to reduce energy consumption, to use smaller aggregates, and to reduce catalyst amount in each reactor in comparison with technical level. |
