Catalytic cracking of polyolefinic plastics with iron-supported active-carbon catalyst under hydrogen atmosphere

On catalytic degradation of polypropylene and polystyrene with iron supported active carbon catalyst under hydrogen atmosphere with semi-batchwise flow apparatus, suppressing radical chain reaction caused some declination of cracking speed. But hydrogenation of radicals and olefins suppressed side-reaction, then high quality oil could be formed. Catalytic degradation of mixed plastic under hydrogen atmosphere was carried out and its valuation as the process was studied. The life of catalytic activity on catalytic degradation of polypropylene was also studied. Original is an abstract.
