In European Union 75% of used tires should be recycled. The most common method of used tires disposal, is burning in cement kilns, which does not solve the problem. Pyrolysis process can be an alternative way of utilization of tires. The aim of the researches was to check the influence of pyrolysis products (gas and oil fractions) on environment. Samples from pyrolysis process, like light oil fractions or pyrolysis gases were analyzed...

Proces pirolizy polega na rozkładzie materii organicznej w podwyższonej temperaturze w warunkach beztlenowych, dlatego może być on stosowany jako alternatywa lub uzupełnienie dla procesu spalania. Piroliza pozwala na uzyskanie substancji chemicznych z polimerów naturalnych i syntetycznych. W umiarkowanej temperaturze (300 - 500 ° C), można uzyskać wysokiej wydajności frakcji ciekłej, natomiast wysokie temperatury sprzyjają powstawaniu...

This review deals with the technologies of limonene production from waste tyre pyrolysis. Thermal decomposition is attractive for tackling the waste tyre disposal problem, as it enables both: energy to be recovered and limonene to be obtained. This material management recycling of tyres is environmentally more beneficial than the burning of all valuable products, including limonene. Given this recoverability of materials from waste...

Gasification and pyrolysis are thermal processes for converting carbonaceous substances into tar, ash, coke, char, and gas. Pyrolysis produces products such as char, tar, and gas, while gasification transforms carbon-containing products (e.g., the products from pyrolysis) into a primarily gaseous product. The composition of the products and their relative quantities are highly dependent on the configuration of the overall process...
