Assessment of the prospects for using thermo-oxidation of electrode pitch to obtain high temperature binding pitch

The paper analyses the products of thermal oxidation of grade B electrode pitch. The research presents the results of analysis of high-temperature pitch production by thermal oxidation of grade B electrode pitch in a reactor with a large gas space. The dependence of the softening temperature and volatile matter yields on the air flow rate for this type of thermal oxidation has been determined. During the experiment, the dependence of the carbonisate yield on the duration of thermal oxidation of grade B electrode pitch has been obtained. Carbonisation was conducted by heating the initial grade B electrode pitch and the pitches obtained by its thermal oxidation. The research establishes criteria for the special type of thermal oxidation to increase the category of coke and shows the results of carbonisation of a pitch-coke mixture containing various types of coke.
