Abstract
The present disclosure relates to a method for separating a carbon isotope and a method for concentrating a carbon isotope using the same, the method for separating a carbon isotope including: cooling a formaldehyde gas to a temperature of from 190K to 250K; and obtaining a mixed gas and residual formaldehyde by photodissociating the cooled formaldehyde gas, the mixed gas including carbon dioxide containing a carbon isotope and hydrogen.
Claims7
A method for separating a carbon isotope (13C) comprising:
- cooling a formaldehyde gas to a temperature of from 190K to 250K;
- and obtaining a mixed gas and residual formaldehyde by photodissociating the cooled formaldehyde gas, the mixed gas including carbon monoxide containing the carbon isotope (13C) and hydrogen wherein a wavenumber of a photodissociation laser at the time of the photodissociating is 28396.1 cm−1, 28401.3 cm−1 or a combination thereof.
