COMPARATIVE STUDY OF GASOLINE OIL WITH EXTRACTED FUEL FROM DEGRADATION OF WASTE PLASTICS BY PYROLYSIS

摘要

Pyrolysis of mixed plastic waste was carried out by developing laboratory scale stainless steel reactor by using one kilograms of mixed plastic waste such as High density polyethylene, Low density polyethylene and Poly propylene (HDPE, LDPE and PPL'The physical properties such as Density, Melt flow index, Melting point for mixed waste plastics was also studied. The comparison of pyrolysis fuel with commercial fuel was manipulated. The maximum temperature in a reactor was kept about 350-500°C. Reaction was carried out with and without using natural zeolite (NZ) as a catalyst. It was found that, time required for completion of the pyrolysis process was 90 minutes without catalyst and 65 minutes with natural zeolite. Results showed that in absence of catalyst, process gives about 54.50% of liquid fuel and in presence of 10 % natural zeolite, about 59.97 % yield is obtained. It was observed that by using natural zeolite, oil percent can be enhanced and one can obtain high calorific value fuel than that of oil without catalyst. Scaling up of the present method would substantially reduce the environmental pollution and degradation and would also help in the pursuit of exploring economically viable recycling system for plastic waste. Hence waste-to-energy technology was applied to extract the expected outcome from disposed waste plastics.
