CARBON MONOXIDE STABLE ISOTOPE CONCENTRATOR AND CARBON MONOXIDE STABLE ISOTOPE CONCENTRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a carbon monoxide stable isotope concentrator and a carbon monoxide stable isotope concentration method which enable ¹³CO to be concentrated at a high concentration by a small number of steps.;SOLUTION: A carbon monoxide stable isotope concentrator is used which comprises: a distillation tower group where a plurality of distillation towers are cascade-connected to distillate stock carbon monoxide, and to concentrate carbon monoxide stable isotope molecules containing 1³C; and a ¹⁸O loss appliance that, by making carbon monoxide stable isotope molecules containing ¹⁸O react by oxidation reduction, converts them into carbon monoxide stable isotope molecules containing ¹⁶O to reduce carbon monoxide stable isotope molecules containing¹⁸O, where the ¹⁸O loss appliance is connected to any other than the distillation tower arranged at a downstream side terminal of the distillation tower group, and where a part or the whole of carbon monoxide with carbon monoxide stable isotope molecules containing ¹³C concentrated is extracted out of the distillation tower and introduced into the ¹⁸ loss apparatus to be returned to the distillation tower.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
