AI Technical Summary
Existing technologies for preparing 13CO2 by catalytic oxidation suffer from problems such as insufficient selectivity of the catalytic system, inaccurate control of reaction temperature, poor sealing of the equipment, and complex product separation and purification. These problems result in low product purity, loss of isotope abundance, and complex operation, making it difficult to meet the needs of high-end applications.
By employing a CuO catalytic particle and quartz wool-quartz sand composite bed structure, combined with an integrated device design, and through high-purity nitrogen purging, low-temperature collection, and multi-stage partial pressure purification processes, the efficient and directional conversion and purification of 13CO to 13CO2 is achieved.
It significantly improves catalytic conversion efficiency and selectivity, with product purity reaching 99.5% and 13C abundance recovery rate ≥99%. It is easy to operate, meets the requirements of green chemical production, and is suitable for industrial scale-up.
