The present invention relates to a method for recycling scrap rubber comprising the steps of pyrolyzing scrap rubber to obtain a char material and milling the thus obtained char material. The present invention also relates to carbon black powders and carbon black pellets obtained by the method according to the invention. Moreover, the present invention relates to the use of said carbon black powder and to compositions comprising said carbon black powders.

Methods to produce carbon black from low-yielding carbon black feedstocks are described using a process that involves the use of electrical energy to cause formation of carbon black from a carbon black feedstock(s). Carbon blacks produced from these carbon black feedstocks are further described. The advantages achieved with the methods are further described.

The invention relates to a thermolysis system and method for obtaining recovered carbon black and fuel from disused tires, which includes a thermolysis reactor and a flash vessel acting jointly to refine fuel without the need for post-treatment to clean same. During thermolysis, condensers are cleaned without needing to cut the flow or deviate the gas stream, since the deposits formed inside tubes of a heat exchange system are cleaned using a part of the fuel obtained. The carbon black obtained is comparable to existing semi-reinforcing carbon blacks. The obtained fuel has a high content of aromatic compounds, and its carbon content is reduced to 3% by weight, up to 0.8% by weight, with respect to fuels obtained in pyrolytic processes, without requiring post-treatment such as distillation processes or catalytic treatment.

The present invention relates to a process for the processing and/or purification of carbon black comprising the steps of: a) providing carbon black containing impurities b) providing an aqueous fluid comprising a nitrogen hydride c) providing an alkali metal hydroxide and/or an alkali metal d) contacting the mixture of step a), the fluid of step b) and the alkali metal hydroxide and/or alkali metal of step c) e) subjecting the composition obtained in step d) to an elevated temperature in the range of 80 to 240 C. and an elevated pressure in the range of 5 to 50 bar f) separating a carbonaceous solid from the composition obtained in step e). The present invention further relates to the use of a nitrogen hydride as a dispersing agent for producing and/or stabilizing an aqueous suspension.
