WebA relationship has been proposed to evaluate the coking values of coal tar pitches from the knowledge of their three other characteristics, namely, softening point, benzene … WebA coal tar obtained by coal coking was distilled in a laboratory into fractions of initial boiling point IBP -180℃ (gasoline-like fuel), 180℃ - 360℃ (diesel-like fuel), and >360℃ (residue or coal tar pitch). The coal tar pitch was added into road bitumen by up to 1 - 5 wt% and investigated the alteration of physical and chemical properties.
WebThe pitch with the largest amount of primary QI showed higher coking value, and thus it gave higher bulk density of baked anode. The increase in bulk density improved compressive strength. ... “High Softening Point Coal Tar Pitch as Binder Pitch,” Light Metals 2010, 2010, 909–911. Google Scholar Winfried Boenigk, Claudia Boltersdorf ... WebIn addition, coal tar pitch has a similar composition to coke breeze and low impurity content, making it an optimal binder for preparing formed coke products using coke breeze [9], [21], [28], [29], [30]. However, the binding of coal tar pitch is poor until it is heated to a molten state, which makes its utilization process too complicated [31 ...
