Abstract
Pyrolysis of plastic waste currently gained high attention from the researchers in order to convert it into liquid fuel to overcome the depletion of liquid fossil fuel. In the present investigation, pyrolysis of waste LDPE and HDPE wastes were investigated using silica-alumina and activated carbon dope silica-alumina which were synthesized by sol-gel process. Catalysts were characterized with FTIR, XRD, SEM, EDS, BET etc. Pyrolysis experiments were carried out in a batch reactor. About 96% conversion was achieved by using the ratio of polymer and catalyst in 25 wt%. Among the products, about 43 wt% was gasoline and 28 wt% was kerosene. Characterization of the liquid hydrocarbon mixture was performed with infrared (FTIR), nuclear magnetic resonance spectroscopy (1H NMR, 13C NMR and DEPT-135) and gas chromatography–mass spectroscopy (GC-MS). It was found that the liquid products consist of branched saturated and unsaturated hydrocarbons. The fuel properties of the gasoline-range distillate (gasoline fraction) were comparable to those of ultra-low sulfur gasoline. This can be used as regular petro-fuel. Thus, this pyrolysis technology should be commercialized in order to get waste plastic free clean environment by cost effective way.
