- Abstract
- CO capture from mixture approximate in composition to the products of steam reforming of methane has been studied using the sorbent 17 wt. % NaNO/MgO. The possibility of capturing up to 5 mmol CO 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/CeZrO catalyst and 17 wt. % NaNO/MgO CO 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 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 per gram of the sorbent (53.7 mas. %).
