Abstract

In a process for producing carbon fibres from coal tar pitch, the coal tar pitch is filtered before being spun and the pitch filtrate is distilled in a thin-film evaporator in order to increase its softening point over 260 C. A pure and homogeneous hard pitch is thus obtained, without the re-formation of infusable, chinolin-insoluble components. The most difficult and cost intensive step of the fibre production process, namely the thermal aftertreatment of the spun pitch fibres, can thus be easily and quickly carried out. The subsequent thermal treatment is carried out in a cyclic treatment installation.
