Production of Mesophase Pitch from Coal Tar and Petroleum

Ashland-240 petroleum pitch, coal tar pitch and their SFE extracts and residues were dissolved in THF before analysis. Extraction from Ashland-240 petroleum pitch and coal tar pitch For each extraction process, 1 g of either the Ashland-240 petroleum pitch or coal tar pitch, supported on 2 g

Carbon Materials - Shamokin Carbons

Coal tar pitch is a by-product resulting from the thermal distillation of bituminous coal or graphite manufacturing. Because it is condensed from the gas phase, coal tar pitch is inherently low in ash, metals, and other non-carbonaceous substances. Pitch coke is extremely high in carbon and low in impurities.
