It is estimated that about 1.5 billion tires are produced worldwide each year. After use they pass to the stream of waste, representing a significant part of them [1]. So far, the main method of tires thermal recycling was burning, mainly as a fuel in cement plants. An alternative way of car tires reprocessing is pyrolysis, which is a thermal, anaerobic decomposition of organic material contained in the tyres at elevated temperature (from 300°C to 900°C). Pyrolytic oil is one of the key products of pyrolysis. The oil is a dark brown or black coloured liquid of medium viscosity with a characteristic sulphurous smell. It is mainly a mixture of paraffin, olefin and aromatic hydrocarbons and their derivatives. Properties of pyrolytic oil are similar to heating or diesel fuel, which indicates the possibility of its application in the fuel and heat industry [2].
