Difference Between Coal Tar and Asphalt Since the Industrial revolution, bituminous materials are very much preferred in building and road constructions. These materials are composed of highly molecular weight hydrocarbons, and soluble in carbon disulfide. There are many grades of bitumen, each of which exhibits different characteristics. The performance of each grade of bitumen depends ...

Abstract. The functional and group composition and structure of β and α 2 fractions of mediumtemperature coal pitch fraction (in powder form) are investigated by methods such as elemental analysis, electron microscopy, IR spectroscopy, ESR, Xray diffraction analysis, derivatographic analysis, and chromatography and mass spectrometry. The morphology and structure of the coke residues from ...

Monolithic activated carbon (MAC) has been produced from steam activation of monoliths prepared by mixing coal powders with hightemperature coal tar binder for a long time. However, this process leads to poor working conditions, environmental pollution, and waste of resource. This study investigated the use of coal tar pitch as binder to prepare MAC with high surface area, micropore ...

Guo [28] has tried to cocarbonize petroleum pitch with coal tar pitch to prepare spinnable pitch for carbon fiber. They have found that the rheological property of spinnable pitch was improved, but its softening point was still not suitable after cocarbonization. The formation of mesophase is hard to control due to hightemperature heat ...
