| Abstract [eng] |
Plastic plays an important role in modern human life. Most plastic is used in the production of packaging and disposable tableware. The lifetime of these products is short and most of them become waste in a short period of time. Plastic waste is a growing concern as plastics are not biodegradable and they require hundreds of years to decompose. Moreover, plastics pollute the environment and the oeans, effect their ecosystem and harm animals in many ways. The best way to reduce plastic waste would be converting them into new products or energy source. Plastic waste pyrolysis is a process, where plastic material is heated in an inert atmosphere and at elevated temperature. During this process, the organic part of the plastic polymer material decomposes and generates liquids and gases, that are used as alternative fuels or raw materials. This method is suitable for complex polymer waste, that contains a number of highly mixed materials and prior seperation step is not needed. In this experiment, pyrolysis oils was produced of macroalgae, PP and HDPE plastics waste without and with reagent (2-ethylhexyl nitarte). The course of the pyrolysis process was analyzed and the yields of pyrolysis products were calculates depending on the type of raw material and reagent. The analysis using gas chromatography – mass spectrometry (GC – MS) of the pyrolysis oil was carried out to determine its composition and product distribution. Also for oils and mixtures were determined: density, viscosity, oxidation stability, fractional compasition and other necessary qualitative parameters. |
