【Abstract】 The technology of using supercritical fluids have many merits which not existed in the traditional technic, such as high speed, high efficiency, smaller energy consumption and little pollution. The supercritical fluids without poison non combustible do not pollute the environment, so those fluids can be used to carry out a mass of high effective chemistry engineering processes. This paper introduced the physical and chemical characteristics of supercritical fluids including relative density, viscosity and diffusion coefficient. At the same time in the paper many influences to the chemical reaction were explained. Especially introduced the characteristics of supercritical water and the application of supercritical fluid in supercritical chemical reaction engineering. Moreover, the green chemical process is realized by supercritical fluids.更多还原
