Catalytic pyrolysis of waste polypropylene with zeolites

Popis výsledku v původním jazyce

Poster presentation. In the Czech Republic, enormous amount of plastics ends up in landfills. Plastic waste is one of the most promising resources in fuel production. Plastic waste can be converted into valuable source of energy. Zeolites have proven to be successful catalysts in the degradation of polypropylene into light hydrocarbons. ZSM-5 zeolite is one widely most used catalyst, given its strong acidity and shape selectivity, which depends on the particular textural properties, structure and pore size of this catalyst. ZSM-5 (type SM 27) was used for catalytic depolymerization. The effect of temperature and catalyst on product distribution in PP pyrolysis was monitored. Thermal and catalytic depolymerization of PP was carried out include the possibility of reusing of the catalyst, in the temperature range between 450 oC and 550 oC, heating rate of 10 oC/min and residence time of 90 minutes were used for all experiments. The catalytic pyrolysis created 60 wt% of condensate which was contained mainly by BTEX group. The amount of gas composed of C1-C4 Alkanes. The results show that the regenerated catalyst had the same efficiency as the original catalyst.
