Production of carbon black stock by extraction of thermal-cracking bottoms of semitar
1969
1.
It has been shown that the 250–420°C fraction from the thermal cracking of semitar can be used in the production of carbon black stock by selective extraction.
2.
Furfural is the most suitable extraction solvent.
3.
It is recommended that the thermal-cracking residue should be used fully or partially in the production of carbon black stock.
