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%.
