Catalytic Cracking of LDPE over Used Fluid Catalytic Cracking (FCC): II-Effect of Catalyst/Polymer Ratio (C/P)

The rapid rate of plastic consumption throughout the world and low service life of all plastics has led to the creation of increasing amounts of waste [1-2]. There are several methodsfor disposal of plastic waste, i.e. landfill, incineration (energy recovery), true material recycling (similar recycled product or monomer recovery), and chemical recovery [3]. One of the most useful ways of chemical recovery is catalytic pyrolysis.In which polymer chains break down into useful lowermolecular weight compounds [4]. In present work the effect of Catalyst to Polymer ratio (C/P) on catalytic pyrolysis behavior of LDPE over used FCC has been investigated
