ABSTRACT: Polypropylene (PP) is rated first as volume
leader in the plastic sector. Its non-biodegradable property poses serious
environmental problem in case of disposal. The catalytic cracking of PP was
performed with various catalysts i.e. ZSM-5, Zeolite, RB and SPS. The cracking
was observed under different feed to catalyst ratio i.e. 1:1 to 5:1. The fluidized
bed reactor was fabricated with arrangement to measure the temperature ranging
from 100。C to 800。C. The effective of feed to catalyst ratio was found 3:1 at a
temperature range of 420。C - 510。C and catalyst ZSM-5 gives maximum liquid
conversion of waste PP. Conversion of PP to liquid fuel will not only resolve
the problem of disposal of waste polypropylene plastic but also give a value
aided product.
