Comprehensive analysis of pyrolysis oil obtained from waste tire in a water vapor environment

Abstract

Determination of the composition of pyrolysis products of organic compounds is a very difficult task due to their multicomponent nature [1–3]. Pyrolysis oils formed from rubber products and organic polymer wastes contain various classes of organic compounds with a huge spread in molecular weight and polarity: hydrocarbons, amides, phenols, amines, organosulfur compounds, etc. [1]. At the same time, the results of qualitative and quantitative chromatographic analysis of pyrolysis oils are often ambiguous: there are problems of overlapping peaks and misinterpretation of the data obtained due to the complexity of the matrix and the multicomponent composition [2–5]. Pyrolysis products can be used as valuable hydrocarbons or additives to hydrocarbon fuels. Therefore, the analysis of the chemical composition of pyrolysis oils is important both for assessing the degree of their toxicity and for finding an effective method for their purification.
