Super hard asphalt (SHA) from direct coal liquefaction process as pavement material

Generation and characterization of coal-based needle coke produced by the co-carbonization of coal liquefaction pitch and anthracene oil

“…This phenomenon is attributed to the extremely reactive nature or ultra-high viscosity of the reaction system during the liquid-phase carbonization process. 37,38 In fact, the coal liquefaction pitch (CLP) was obtained from the coal direct liquefaction residue, and thus the average molecular weight of the CLP was relatively higher than that of the common pitch (such as high-temperature coal tar pitch and medium-lowtemperature pitch). Consequently, the reactivity of the pitch molecules in CLP was relatively low.…”
