Scanning Electron Microscopy of Metallurgical Cokes and Residues from Rapid Pyrolysis.
Fuel London 50:457-460
A recent study of cokes by scanning electron microscopy described structures revealed by partial combustion of cokes from two coals of different rank. Different structures have been observed in cokes formed in conventional slow carbonization (3 deg c/min, in the Bureau of Mines-American Gas Association carbonization apparatus) and in residues formed in very rapid heating of small coal particles (8,000 deg c/sec). The article includes photographs of the scanning electron micrographs of the cokes studied.
