Gas-liquid mass transfer in the gas-liquid-solid mini fluidized beds
文献摘要：
The gas-liquid-solid mini fluidized bed(GLSMFB)combines the advantages of fluidized bed and micro-reactor,and meets the requirements for safety and efficiency of green development of process industry.However,there are few studies on its flow performance and no studies on its mass and heat transfer performance.In this paper,the characteristics of gas-liquid mass transfer in a GLSMFB were studied in order to provide basic guidance for the study of GLSMFB reaction performance and application.Using CO2 absorption by NaOH as the model process,the gas-liquid mass transfer performance of GLSMFB was investigated.The results show that the liquid volumetric mass transfer coefficient and the gas-liquid interfacial area both increase with the increase of the superficial gas velocity within the experimental parameter range under the same given superficial liquid velocity.At the same ratio of superficial gas to liquid velocity,the liquid volumetric mass transfer coefficient increases with the increase of the super-ficial liquid velocity.Fluidized solid particles strengthen the liquid mass transfer process,and the liquid volumetric mass transfer coefficient is about 13％higher than that of gas-liquid mini bubble column.
