FIELD: chemistry.SUBSTANCE: system for producing gasoline from natural gas through methanol comprises: a steam reforming apparatus for producing reforming gas via steam reforming of natural gas; a methanol synthesis apparatus for synthesis of methanol from the reforming gas obtained by the steam reforming apparatus; a gasoline synthesis apparatus for synthesis of gasoline from methanol, which is synthesized by the methanol synthesis apparatus; and an air preheating apparatus for preheating combustion air to be fed into the steam reforming apparatus using steam obtained by heating boiler water with synthesis reaction heat in the gasoline synthesis apparatus, or using heat exchange between combustion air and synthesis heat generated in a reaction tube loaded with a gasoline synthesis catalyst, in the gasoline synthesis apparatus.EFFECT: efficient utilisation of reaction heat released during gasoline synthesis, and enabling rapid cooling of the gasoline synthesis column when producing gasoline from natural gas through methanol.4 cl, 1 tbl, 3 dwg |
