Catalytic pyrolysis of polypropylene residues for the obtaining of liquid fuels

Abstract

The present research work seeks to study the variables related to the catalytic pyrolysis of polypropylene waste to obtain liquid fuels. The effect of the reactor temperature and the catalyst/raw material ratio on the yields of liquid products was studied. For the investigation, samples of polypropylene waste from urban solid waste (MSW) were collected and, as a catalyst, the equilibrium catalyst of the Fluidized Catalytic Cracking Unit (FCC) of a local refinery, a scale system was also designed and built. laboratory for catalytic pyrolysis. The experimental operating conditions that maximize the obtaining of liquid fuels were: pyrolysis temperature (reactor) = 873.15 K, ratio of catalyst / Raw Material = 10%.
