The Continuous Moving Bed Process for the Isolation of Pure Benzene from Coal Gas

The moving bed technique was first applied to gas-liquid chromatography by Scott (11,12). A diagram of the moving bed system suitable for gas-liquid chromatography (GLC) was proposed by Scott also in 1956, and the basic system is depicted in figure 25. The original GC system will be used here to explain the principal of the separating process.
