The author conducted a series of experiments on obtaining pitch with increased softening point Tp = 110-120 °C by low-temperature thermo oxidation (up to 300 °C) of electrode coal ash of category B (Tp = 91 °C). The research determines the thermal oxidation conditions for obtaining these types of pitches. The paper also defines the dependences of softening temperature and yields of thermo-oxidation products on process duration and air flow rate
