A New Kind of Renewable Energy: Production of Aromatic Hydrocarbons Naphtha Chemical by Thermal Degradation of Polystyrene (PS) Waste Plastic

Abstract

Polystyrene (PS) waste plastic to renewable energy or naphtha grade fuel production through fractional distillation process was applied and PS liquefaction temperature range was 250˚C-430˚C and fractional column temperature was 110˚C-135˚C for naphtha grade fuel separation. The thermal degradation of PS waste plastic to renewable energy or naphtha grade chemical production was without adding any kind of cracking catalyst and without vacuum system. Polystyrene waste plastic is not biodegradable and its can remain long period of landfill and creating gas emission for that reason its major cause climate change. For experimental purpose raw sample was use 1 kg of PS waste plastic and experiment was performed under Labconco fume hood and experiment was fully closed system, whole experiment was performed into stainless steel reactor. Produced fuel was analysis by gas chromatography and mass spectrometer, FT-IR and DSC. Analysis result indicate for fuel compounds chemical structure, compound band energy and enthalpy, delta H value. Produced fuel sulfur content less then environmental protection agency (EPA) level and fuel could be use for chemical feedstock refinery for further modification. By using this technology can reduce some foreign oil dependency and boost up renewable energy sector all over the world.

Advances in LDPE Nano-Composites for Photodegradation: Strategies, Mechanisms and Applications

“…Modern landfills often incorporate gas collection systems to capture and utilize or burn methane for energy generation, mitigating its environmental impact. Additionally, it requires proper management and monitoring to minimize potential environmental risks [46]. In addition to the environmental considerations, there are social and economic aspects to landfilling LDPE waste.…”

Application of Pyrolysis for the Evaluation of Organic Compounds in Medical Plastic Waste Generated in the City of Cartagena-Colombia Applying TG-GC/MS

“…The generation of these multiple pollutants creates the need to apply cleaner technologies, and one of them is pyrolysis, which provides the potential for energy and fuel recovery [ 26 , 27 , 28 , 29 , 30 , 31 ]. Pyrolysis has been applied to plastic mixtures [ 16 , 27 , 28 , 32 , 33 , 34 ], which makes it possible to recover high-value compounds [ 35 , 36 , 37 ] as well as gasoline [ 33 ] or diesel [ 26 ] range fuels. Pyrolysis then becomes a vitally important tool for the transformation of HRW into raw materials with high added value [ 33 ], and these values depend on the compositions of the hydrocarbons of interest, which are commonly analyzed by analytical techniques such as GC/MS [ 11 , 30 , 38 , 39 , 40 ].…”

Enhancing Heat Transfer Performance in Simulated Fischer–Tropsch Fluidized Bed Reactor through Tubes Ends Modifications

“…Transitioning from non-renewable fuels like oil and coal to clean energy sources and natural gas is critical to climate change policy [3][4][5][6]. Renewable energy sources are expected to become the world's leader in power generation by 2030 [7][8][9].…”
