Experimental Investigation on Pyrolysis of Domestic Plastic Wastes for Fuel Grade Hydrocarbons

Plastics usage is rising daily because of increased population, modernization, and industrialization, which produces a lot plastic garbage. Due to their various chemical structures, long chain polymeric compositions, thermal/decomposition behavior, it challenging recycle these wastes into hydrocarbon fuels. In the current work, domestic waste was pyrolyzed at 473 973 K in fixed bed reactor compared with three virgin plastics LDPE (low-density polyethylene), HDPE (high-density PP (polypropylene), as well mixture (virgin mixed plastics). The pyrolysis results showed that maximum liquid hydrocarbons obtained from HDPE, LDPE, PP, plastic, were 64.6 wt.%, 62.2 63.1 68.6 wt.% 773 K, respectively. composition fuels characterized using FTIR GC-MS, wide spectrum C8–C20 range. Furthermore, fuel characteristics such density, viscosity, fire flash point, pour calorific value examined ASTM standards, found be satisfactory. This study provides an innovative method for recycling economical use transportation.
