Method for producing a hydrocarbon stream

Abstract

The present invention relates to a method for producing hydrocarbons and to a plant (1) for carrying out the method. The method comprises the steps of: carrying out (S10) an endothermic first reaction process, in the form of a reverse water-gas shift (RWGS) reaction, at a first temperature (T1) using a CO2 reactant stream (10) and an H2 reactant stream (12), in order to generate a first intermediate product stream (14) comprising a first CO mass flow (14); carrying out (S20) an exothermic second reaction process, in the form of a Fischer-Tropsch (FT) reaction, at a second temperature (T2) using a the first CO mass flow (14) and an additional H2 reactant stream (16), in order to generate a hydrocarbon stream (18); removing (S30) process heat (20a-d) from the second reaction process; and feeding (S40) a first portion (20a) of the process heat (20a-d) to the first reaction process in the form of a first heat flow (20a). The plant (1) is designed to carry out the method.
