Analysis and Selection of Composite Raw Materials for Carbon Black Production

The availability and possibility of using various alternative types of raw materials for carbon black production have been analyzed. The quality of raw materials was evaluated according to the aromaticity value, correlation index, carbon content, and hydrogen content. Composite mixtures were created and tested under industrial conditions. Two programs for calculating the theoretical yield of carbon black by balance and thermochemical methods have been developed and tested. An evaluation of the carbon black cost was carried out under the conditions of using the residue of tire processing - pyrolysis oil - as a fuel.
