- Аннотация: Today, reducing carbon footprints requires the development of technologies to utilize CO2, particularly by converting it into valuable chemical products. One approach is plasma-catalytic CO2 splitting into CO and O2. The task of separating such a ternary mixture is nontrivial and requires the development of an efficient method. In this paper, we have developed a comprehensive scheme for the separation of a CO2/CO/O2 mixture using membrane technology. The novelty of this work lies in the development of a complete scheme for separating the products of plasma-chemical decomposition of CO2 to produce a CO concentrate. The calculations utilized the principle of a reasonable balance between the recovery rate and the energy consumption of the separation process. This scheme allows production of a CO stream with a purity of 99%. To achieve this goal, we have proposed the sequential use of CO2-selective membranes based on polysiloxane with oligoethyleneoxide side groups (M-PEG), followed by polysulfone (PSF) hollow-fiber membranes to separate CO and O2. For these membranes, we measured the CO permeability for the first time and obtained the selectivity for CO2/CO and O2/CO. The potential of membrane separation was demonstrated through a three-stage process, which includes recycling of the CO removal stream and concentration after CO2 plasmolysis. This process was calculated to yield a highly pure CO stream containing 99 mol% with a recovery rate of 47.9–69.4%. The specific energy consumption for the separation process was 30.31–0.83 kWh per 1 m3 of feed mixture, and the required membrane area was between 0.1 m2 for M-PEG and 42.5–107 m2 for PSF, respectively.
