manufacturing process of coal tar pitch - Henan Technox,
A process for producing mesophase pitch from hightemperature coal tar comprises: removing salts and quinoline insoluble fraction from a hightemperature coal tar to obtain a decant oil; using the decant oil as a hydrogenation feedstock, or predistilling the decant oil to obtain a residue with a boiling point higher than 230 and formulating the residue into a hydrogenation feedstock.Coal-Tar Pitch - an overview | ScienceDirect Topics,Prebake anodes are manufactured by compressing a mixture of petroleum coke aggregates and coal tar pitch binder into blocks typically 40–60 cm wide by 120–150 cm long and 50–60 cm high. Petroleum coke is used because of its high purity. These blocks are baked in anode-baking furnaces above 1100–1200 °C to convert the binder pitch into dense carbon.Aggregate Tar Pitch Production Process,Aggregate Tar Pitch Production Process.
