AI Technical Summary
In the process of large-scale industrial synthesis and scale-up, traditional stirred tank reactors suffer from poor batch-to-batch catalyst consistency due to gravity settling effect, reduced heat and mass transfer efficiency, and inconsistent solvent removal rates, making it difficult to meet the material performance stability requirements for large-scale fuel cell production.
The system employs a horizontally axially positioned heat-insulating cylinder and an internally coaxially rotating reaction cylinder. The reaction cylinder is driven to rotate by a drive component, and the temperature is controlled by a heating element. Centrifugal force is used to spread the liquid film. Combined with a vacuum interface and a solvent outlet interface, the system achieves efficient solvent evaporation and solid-liquid separation, overcomes the gravity sedimentation effect, and ensures consistency in heat and mass transfer efficiency and solvent removal rate.
This study achieved uniform loading, uniform heat transfer, and stable industrial preparation of high-performance fuel cell catalysts, solving the problem of poor batch consistency and improving the performance stability and batch consistency of the catalysts.
