    摘要: PROBLEM TO BE SOLVED: To increase availability of olefin gas by controlling the constituent component of olefin gas formed in thermal decomposition of pyrolysis gas, obtained in a thermal decomposition process, in the presence of a silicate catalyst and to actualize efficient reproduction of the silicate catalyst useful in the thermal decomposition in a chemical recycle method for a waste plastic. SOLUTION: The subject apparatus increases the yield of propylene (C 3 H 6 ) with passage of time. Since the silicate catalyst forms a carbon layer on its catalyst surface as pyrolysis gas is fed, the yield of propylene (C 3 H 6 ) useful as a main raw material for a plastic is raised due to the formation of the carbon layer on the surface of the silicate catalyst.
