The Composition of Pyrolysis Products of used Car Tires used as Liquid Fuel
Abstract:
Waste disposal technologies, which allow obtaining useful products, are one of the most powerful means of environ mental protection through the rational use of waste as raw materials for industry. One of such technologies is the pyrolysis of used car tires. As a result of pyrolysis, gaseous, liquid and solid products are formed. These products are used as fuel, in particular, the liquid fraction can be used as diesel fuel. The content of the liquid fraction was analyzed by the method of two-dimensional gas chromatography using TOF MS. More than 6600 compounds have been identified. The majority of the pyrolysis mixture consists of low-mo lecular volatile fractions the liquid fraction contains saturated, unsaturated, aromatic hydrocarbons, a significant number of compounds, which include nitrogen, sulfur and halogens atoms. When juxtaposing the chromatograms of the liquid fraction of the pyrolysis mixture with the chromatograms of petroleum products, in particular, diesel fuel, it can be seen that they largely contain the same components, which indicates that the properties of the liquid pyrolysis fraction are close to petroleum products of natural origin.
