Abrégé

The pyrolytic carbon black derived from used tyres underwent puri fication processes that made it more environmentally compatible and subsequently a surface activation process that imparted thereto reinforcing properties, when used as a reinforcing filler in new rubber compounds, decidedly superior to those imparted by a common commercially available pyrolytic carbon black and comparable to the mechanical properties produced by conventional " furnace" blacks of the N772, N550 and N330 type.

Abrégé

A method for purifying carbon black obtained from pyrolysis of used tires by solvent extraction involves removal of residues of pyrolyzed rubber deposited on the surface of the carbon black obtained from the pyrolysis and the polycyclic aromatic hydrocarbons contained therein. The method also involves extracting zinc from the purified carbon black using carboxylic acids of natural origin.

Abrégé

The present invention relates to a purification process of the carbon black obtained from the pyrolysis of used tyres by means of solvent extraction characterized by low or zero toxicity and environmental impact, preferably - but not exclusively - derived from raw materials from renewable and non- fossil sources, i.e., by means of heat treatment in an inert atmosphere or by means of heat treatment in an inert atmosphere followed by solvent extraction, in order to remove the residues of pyrolysed rubber deposited on the surface of the carbon black obtained from the pyrolysis and the polycyclic aromatic hydrocarbons contained therein. The present invention also relates to a process for the extraction of zinc from the carbon black obtained from the pyrolysis previously purified by means of solvent extraction or by heat treatment or by heat treatment followed by solvent extraction, making use of carboxylic acids of natural origin, such as citric acid and tartaric acid obtained from completely renewable sources.
