Pitch Production from Mixtures of Coal Tar and Rubber Crumbs

Pitch Production from Mixtures of Coal Tar and Rubber Crumbs ISSN 1068-364X, Coke and Chemistry, 2018, Vol. 61, No. 8, pp. 305–307. © Allerton Press, Inc., 2018. Original Russian Text © Ch.N.

Ultrasound treatment of a tar–crumb mixture and subsequent oxidation in air at 240–360°C may be used to produce an analog of coal pitch (binder) and a light fraction. The binder characteristics may be regulated in terms of the softening temperature, which is deter- mined by the duration of oxidation.
