Gaseous Products from Scrap Tires Pyrolisis

Abstract

Abstract: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 using gas chromatography. The pyrolysis installation should be hermetical, because of the PAHs which were detected in a light fraction of oil. In exhaust gases BTEX and PAHs were not detected.

Fuel-oils from co-pyrolysis of scrap tyres with coal and a bituminous waste. Influence of oven configuration

“…In this procedure sulphur is added to form crosslinks between the polymer chains. In order to endow the rubber with superior mechanical properties [9,20].…”

“…Blending TC with coal yields an oil with a slightly lower HHV, but co-pyrolysis of RF with the bituminous waste increases the HHV of the oils due to the increase in carbon content. The oils produced from the pyrolysis of tyre wastes and those from their co-pyrolysis with coal and a bituminous waste are comparable to the HHVs of other fuels [20,[23][24][25][26]. A common limiting factor of fuel oils is their sulphur content.…”

“…This study focussed on the bands which correspond to various oxygenated and nitrogenated functionalities together with C-H stretching in aromatic and aliphatic compounds and C=C bonds in aromatic compounds [3,9,20,[27][28][29].…”

Thermomechanical reclaiming of ground tire rubber via extrusion at low temperature: Efficiency and limits

“…The rising amount of the waste rubber is a threat to the natural environment. This explains legal and financial regulations , and heightened interest in the environmental‐friendly technologies based on the ground tire rubber (GTR) as substrate. Searching for new forms of material recycling of waste rubber, being an alternative for common used energy recovery, is a subject of interest of many research centers and companies around the world.…”

Characterization and properties of LDPE/(ground tire rubber)/crosslinked butyl rubber blends

“…At present, reducing the size in the form of grinding is among the most common of the applied scrap rubber recycling technologies; it consists of mechanical disintegration of the scrap rubber material until the required particle size has been reached. The disintegrated scrap rubber containing high‐quality material can be used, among other things, as filler in thermoplastic compositions , thermoplastic elastomers , and rubber compounds , as well as as an asphalt modifier , a cement modifier , an absorbent , and a substrate used in the processes of pyrolysis and devulcanization . In general, the increased content of ground tire rubber (GTR) in polymer composition results in lower mechanical properties of the obtained products.…”
