FIELD: technological processes.
SUBSTANCE: present invention relates to a method of producing one or more reaction products by a subsequent concomitant reaction in which compounds with a higher molecular weight are formed, at least partially, from low molecular weight synthesis gas (3) compounds, involving the following steps: - formation of synthesis gas (3) containing CO and H2, - introducing at least a portion of synthesis gas (3) into reactor (104), and also conducting a further concomitant reaction in reactor (104), wherein product flow (5) is formed, containing compounds with higher molecular weight, CO2, CO and H2, - separation of product flow (5) in separating device (105) into first flow (8), having compounds with higher molecular weight, and also to second flow (6), including CO2, CO and H2. At least CO2 is separated from second flow (6) in adsorption device (103) at variable temperature downstream of separator (105) by adsorption at variable temperature, wherein, in adsorption at variable temperature, CO2 is adsorbed on at least one adsorbent, and at least one saturated CO2 adsorbent is regenerated by heating at least one adsorbent, wherein CO2 is desorbed, and wherein at least one saturated adsorbent is heated by at least indirect heat transfer from the heat carrier fluid to the adsorbent, wherein a flow that is output from adsorption device (103) at variable temperatures, and from which CO2, is fed into a circulation circuit to reactor (104), and that synthesis gas (3) is passed into adsorption device (103) at variable temperature before being fed into reactor (104).
EFFECT: disclosed method increases efficiency of using carbon and reduces CO2 emissions.
