✦ Synopsis

Structural changes which accompany the catalytic graphitization of carbon have been investigated. Utilizing X-ray diffraction and high temperature microscopy techniques, the effectiveness of various additives in promoting the formation of graphite from a variety of carbon materials of varying degrees of graphitizability is elucidated.

  1. The development of mesophase microstructures during pyrolysis of selected coker feedstocks R. J. Price and J. L. White (Gulf General Atomic Company, Sand Diego, California). Polarized light microscopy was used to observe the formation of mesophase microstructures during the pyrolysis of selected coker feedstocks, including a vacuum-reduced crude, an air-blown asphalt, a thermal tar, and gilsonite. These materials developed a range of microstructural components characterized by extinction contour patterns differing widely in anisotropy and contour spacing.
