Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a ...
1. Introduction Carbon monoliths with foamlike hierarchical pore structures and connected macropores have potential applications in high temperature insulation, electrodes for electric energy storage devices, thermal energy storage systems, and as structured catalyst supports and adsorbents [1].
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 ...
