AB  - Catalytic cracking of high-density polyethylene (HDPE) over fluid catalytic 
      cracking (FCC) catalysts (1:6 ratio) was carried out using a laboratory fluidized 
      bed reactor operating at 450 degrees C. Two fresh and two steam deactivated 
      commercial FCC catalysts with different levels of rare earth oxide (REO) were 
      compared as well as two used FCC catalysts (E-Cats) with different levels of 
      metal poisoning. Also, inert microspheres (MS3) were used as a fluidizing agent 
      to compare with thermal cracking process at BP pilot plant at Grangemouth, 
      Scotland, which used sand as its fluidizing agent. The results of HDPE 
      degradation in terms of yield of volatile hydrocarbon product are fresh FCC 
      catalysts>>steamed FCC catalysts approximately used FCC catalysts. The thermal 
      cracking process using MS3 showed that at 450 degrees C, the product distribution 
      gave 46 wt% wax, 14% hydrocarbon gases, 8% gasoline, 0.1% coke and 32% 
      nonvolatile product. In general, the product yields from HDPE cracking showed 
      that the level of metal contamination (nickel and vanadium) did not affect the 
      product stream generated from polymer cracking. This study gives promising 
      results as an alternative technique for the cracking and recycling of polymer 
      waste.
