摘    要:利用微反应器制备纳米碳酸钙,得到平均粒径在25-55nm之间的超细CaCO3颗粒.研究了不同操作条件对颗粒粒径的影响,并使用XRD、TEM、比表面积仪(BET)等仪器对样品进行了分析.结果表明,在优化条件下制得的纳米CaCO3颗粒有很好的分散性能,同时CO2的利用率可达到80%以上.

关 键 词:纳米碳酸钙  微反应器  微通道  气-液两相流  分散

Abstract:Using the preparation of nanometer calcium carbonate microstructure reactor pilot experiment, Ultrafine calcium carbonate particles with average crystal between 25-55nm are produced by membrane dispersion precipitation technology. The influence of the different operating conditions on the particle size are investigated and the samples are analyzed by using XRD, TEM, specific surface area instrument (BET). The results show that the prepared nanometer calcium carbonate particles have good dispersibility under the optimum conditions, at the same time the utilization of CO2 up to 80%.
Keywords:nano-CaCO3  microstructure reactor  microchannel  gas-liquid two phase flow  mass transfer
