摘要: A POROUS CATALYST BASED OR USPPORTED MATERIAL, FOR EXAMPLE ALUMINA, IS INITIALLY SATURATED WITH A POLYMERIZABLE HYDROCARBON, FOR EXAMPLE STYRENE, WHICH IS THEREAFTER POLYMERIZED. SUBSEQUENT IMPREGNATED SUPPORT IS SUBSEQUENTLY WITH CATALYTIC MATERIALS IS THUS RESITRICTED TO THE PERIPHERAL SURFACE THEREOF. THE IMPREGNATED SUPPORT IS SUBSEQUENTLY CALCINED WHEREBY THE HYDROCARBON POLYMER IS DEPOLYMERIZED AND SEPARATED THEREFROM.
