【Abstract】 The application of the green chemical technologies, such as supercritical technology , microwave technology etc. in the separation and further processing of coal tar is investigated. By the utilization of supercritical CO2 to separate tar, the similar result gained with conventional separation process can be achieved, the process is high efficiency and low energy consumption. The influences of temperature and pressure on separation process are discussed. It is thought that clean and high efficient green chemistry technology is the developing trend for organic chemistry and chemical industry. The study on the technologies for solid acid catalyst, ion liquid and supercritical liquid incoal tar chemical field is of great significance for widening research orientation.更多还原
