The traditional technology for separation of Cs hydro- carbons from pyrolysis gas involves the two-step extractive rectification, the azeotropic super-rectification and other methods that have the disadvantages of high consumption of solvents, high operating temperature and low purity of products. The Chemical Separation Research Institute of Nanjing University of Technology on the basis of research work conducted over the past several years has successfully developed the technology of one-step azeotropic distillation coupled with one-step extractive distillation, which not only can separate a mixture containing isoprene and n-pentane,
