Pyrolysis of polypropylene (PP) waste was carried out by developing lab scale borosilicate glass reactor of one litre capacity. Reactions were carried out by using about 200 grams of PP waste. The nitrogen gas was purged in required quantity in the reactor to create pyrolytic condition. The maximum temperature in a reactor was kept about 450C. Reactions were 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 80.82% of liquid fuel and in presence of 10 % natural zeolite, about 86.40 % yield is obtained. It is 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. GC-MS results of oil samples showed presence of petroleum fractions (C-C20) with some high molecular weight fractions from C20-C30.
