Abstract
A process for isolatingO from water and a process for concentratingO by using the same are provided. The process for isolatingO from water includes: mixingO-containing water with formaldehyde to prepare an aqueous formaldehyde solution; heating the aqueous formaldehyde solution to generate a vapor mixture containing water vapor and formaldehyde vapor; and obtainingO-depleted water, residual formaldehyde, and a gas mixture containing hydrogen andO-enriched carbon monoxide, through photodissociating the vapor mixture. AnO-enriched water production process includes: an operation of adding hydrogen to the gas mixture to induce a catalytic methanation reaction to synthesize methane (CH) andO-enriched water (HO) through methanation, the operation being carried out following the process for isolatingO from water.
