Title:
PROCESSES FOR PRODUCING 15 O−CARBON MONOXIDE AND 15 O−CARBON DIOXIDE AND PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2003/046930
Kind Code:
A1
Abstract:
Nitrogen gas containing carbon monoxide is irradiated with deuteron beams, and the [15O]CO generated by a nuclear reaction is recovered. Since no heating step is necessary, [15O]CO can be easily supplied in a short time. Also provided is a method of generating [15O]CO2 which comprises bringing [15O]CO into contact with an oxidation catalyst. The use of an oxidation catalyst enables [15O]CO2 to be generated at ordinary temperature.
