Abstract

Every year, millions of tons of plastic waste grow up in the environment, contributing to global warming, the deaths of numerous species, and an increase in both animal and human illnesses.Pollution formed by polystyrene is one type of waste.This work uses a plasma technique to generate nickel oxide and barium oxide nanoparticles. The data were examined usingatomic absorption spectrometry (AAS), field emission scanning electron microscopy (FE-SEM), and UV- visible spectroscopy (UV). In the tests mentioned above, the average size of the created barium oxide nanoparticles was 45.73 nm while the average size of the created nickel oxide nanoparticles was 40.37 nm.Then, using the produced nanoparticles, we made saline nanocomposites. Different nanocomposites were created utilizing various nickel oxide nanoparticle concentrations (25.3, 50.6, and 75.9 ppm). In addition to the creation of several nanocomposites utilizing varying concentrations of barium oxide nanoparticles (25.9, 51.9, and 77.8 ppm), 20 ml of methanol and 3 g of nickel chloride were added with stirring for 48 hours for each concentration mentioned.our study including improving the thermal degradation products of polymers by using the above-prepared salt nanocomposites with different concentrations. In each experiment, one of the above concentrations is added to polystyrene. From thermal decomposition by simple distillation, we obtained a liquid fuel from each experiment at 280 °C and 350 °C. We note that the decomposition time decreases with an increasing concentration of nanocomposites.For polystyrene decomposition products at 280 °C by using the above-prepared salt nanocomposites with different concentrations. We obtained a liquid that has some of the high properties of the fuel. As the concentration of the nanocomposite increases, we note: an increase in the volume of the product; a decrease in density and viscosity; an increase in aniline point, and an increase in the octane number, especially with 104.7 at 25.3 ppm for NiO and 104.8 at 25.9 ppm for BaO; The cetane number is zero for all concentrations. For polystyrene decomposition products at 350 °C using NiO or BaO nanocomposites at different concentrations, we note: decreases in the product volume, density, and viscosity; an increase in the octane number, especially with 105 for both 50.6 ppm for NiO and 77.8 ppm for BaO; the cetane number is zero for all concentrations.
