超重力微波耦合强化碳酸氢锂热解过程机制研究

The pyrolysis process of hydrogen lithium carbonate, with the technical bottleneck of the mismatch of heat transfer/mixing efficiency and reaction process, exhibits the low product quality and uncontrollability of product performance. In view of these, this project proposes the investigation on the mechanism of the pyrolysis process of hydrogen lithium carbonate under a higee-microwave field based on the advantages of micromixing intensification in a rotating packed bed (RPB, HIGEE) and heat transfer intensification in a microwave field. The heat transfer mechanism of the pyrolysis process will investigated to create the novel device coupled with higee and microwave. Also, the reaction and crystallization kinetics as well as the intensification mechanism of the pyrolysis process of hydrogen lithium carbonate under an higee-microwave field will be investigated. On basis of these, the process research on the synthesis of lithium carbonate via the pyrolysis process of hydrogen lithium carbonate under an higee-microwave field will be carried out. Finally, the new mechanism and rule of the pyrolysis process for regulating the coordination of heat transfer/mixing efficiency and reaction process by using the higee-microwave reactor. This project will provide a novel technical route for the pyrolysis process of hydrogen lithium carbonate, and establish the theoretical foundation for its industrial application.
