活性炭在超临界流体中的改性研究

由于超临界流体的特殊性质,研究超临界流体在不同领域的应用越来越广泛,如超临界萃取技术、超临界流体色谱技术、超临界流体反应技术和超临界水氧化技术等。活性炭由于巨大的比表面积及特殊的表面结构可使催化剂的活性组分得到充分分散,活性炭的表面结构和性质则直接关系到由其制备的催化剂上活性组分分散度及活性等,因此,对活性炭表面进行适当的改性处理并研究处理方法对活性炭表面性质及催化活性的影响意义重大。

Research on the modification of activated carbon in the supercritical fluid

In recent years,the application of supercritical fluids in different fields is studied more and more widely due to its special nature.The supercritical fluid techniques include ultra supercritical extraction technology,supercritical fluid chromatography technology,the technology of supercritical fluid reaction,and supercritical water oxidation technology,etc.The activated carbon can make the catalyst active components fully dispersed due to its huge specific surface area and special surface structure.The surface structures and properties of activated carbon directly relate to the activity and dispersion of the catalysts,therefore,the appropriate modification of the surfaces of activated carbon and study of the effects of treatment methods on surface properties and catalytic activity of the activated carbon are very meaningful.
