The possibility of capturing up to 5 mmol CO<sub>2</sub> per gram of the sorbent (24.4 mas. %) at temperatures of 200–220°C and a mixture pressure of 10 atm has been demonstrated. It has been found that the regeneration of the sorbent proceeds faster and deeper at atmospheric pressure in a stream of humid nitrogen. For the first time the water-gas shift reaction on the mechanical mixture of 5 wt. % Pt/Ce<sub>0.75</sub>Zr<sub>0.25</sub>O<sub>2</sub> catalyst and 17 wt. % NaNO<sub>3</sub>/MgO CO<sub>2</sub> sorbent at a pressure of 10 atm has been studied. It has been shown that hydrogen purity more than 99% in dry gas mixture is provided during 8 minutes at the reaction (sorption) temperature 260°C, pressure 10 atm and GHSV 8000 h<sup>–1</sup> on the mechanical mixture of the catalyst and the sorbent by volume ratio 1:2 respectively that corresponded to a sorption capacity of about 11 mmol CO<sub>2</sub> per gram of the sorbent (53.7 mas. %).</p></abstract><trans-abstract xml:lang="ru"><p>Исследовано поглощение СО<sub>2</sub> из смесей, приближенных по составу к продуктам паровой конверсии метана, с использованием поглотителя на основе MgO, модифицированного 17 вес. % NaNO<sub>3</sub>. Показана возможность улавливания до 5 ммоль СО<sub>2</sub> на грамм поглотителя (24.4 мас. %) при температурах 200–220°С и давлении смеси 10 атм. Установлено, что регенерация сорбента быстрее и глубже протекает при атмосферном давлении в токе влажного азота. Также в работе впервые изучена реакция паровой конверсии СО на механической смеси гранул катализатора 5 вес. % Pt/Ce<sub>0.75</sub>Zr<sub>0.25</sub>O<sub>2</sub> и поглотителя СО<sub>2</sub> 17 вес. % NaNO<sub>3</sub>/MgO при давлении 10 атм. Обнаружено, что при температуре реакции (сорбции) 260°С, давлении 10 атм и нагрузке 8000 ч<sup>–1</sup> на механическую смесь катализатора с поглотителем в объемном соотношении 1:2 обеспечивается чистота получаемого водорода более 99% на сухую смесь в течение 8 мин, что соответствует емкости сорбента около 11 ммоль СО<sub>2</sub> на грамм поглотителя (53.7 мас. %).</p></trans-abstract><kwd-group xml:lang="en"><kwd>sorption-enhanced water-gas shift reaction</kwd><kwd>water-gas shift reaction</kwd><kwd>magnesium oxide</kwd><kwd>CO<sub>2</sub> capture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сорбционно-каталитическая паровая конверсия монооксида углерода</kwd><kwd>паровая конверсия СО</kwd><kwd>оксид магния</kwd><kwd>сорбция СО<sub>2</sub></kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда в рамках проекта № 24-73-10134 (https://rscf.ru/prjcard?rid=24-73-10134).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Arutyunov V. // Academia Letters. 2021. https://doi.org/10.20935/AL3692</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>LeValley T.L., Richard A.R., Fan M. // Int.
