Title:
Separation and Characterization of Municipal Plastic Waste Pyrolysis Fuel Using 20 Kg Scale Vacuum Distillation System for Boiler Fuel and Naphtha Applications
Description:
Pyrolysis is a very promising thermochemical conversion technology for converting the plastic waste into energy to solve the plastic waste issue worldwide. In this work, a 20 kg scale vacuum distillation tower was used to separate the plastic pyrolysis fuel into 74 fractions at different AET (atmospheric equivalent temperature). The samples from No.1 to No.25 showed similar properties to gasoline, including carbon range: C6 -C11 , viscosity range: 0.55-0.72 cSt and HHV: 42-45 MJ/kg. The samples from No.33 to No.48 exhibited kerosene-like properties such as carbon range: C 10 -C 20 , viscosity range: 1.07-2.53 cSt40 ℃ and HHV: 44-45 MJ/kg. The samples over No.60 contained heavy waxy content (> C 20 ) with a high viscosity of 3.12-7.55 cSt. After separation, the O/C ratio decreased from 0.033 in plastic pyrolysis oil to 0.001 when the H/C ratio was about 1.90. GC-MS analysis showed two major chemical groups of paraffins (20-40%) and olefins (16-41%) in all fractions. The uniform transparent pictures and FTIR analysis showed a good miscibility of pyrolysis fuel and diesel. Finally, both characteristics of distillates and the AET conditions can be further used for the design of scale-up vacuum distillation setup for targeting desired products
