The effect of calcium, iron, silicon, titanium and vanadium was determined on the rates of carbon-oxygen, carbon-carbon dioxide and carbon-steam reactions. A general equation describing the weight loss-exposure time relationship was also developed for all reaction systems investigated. ## 84. Infiu

β¦ Synopsis
Thermal treatment of soft carbons leads to progressive graphitization. It is improbable in nature since it requires a high activation energy. Graphite formation is thus attributed to shear stresses caused by pressure and geothermal gradient as in high pressure-high temperature experiments. A thermally stable carbon appears first (partially graphitized), then graphite.

Current-potential curves were determined during the application of a triangular potential sweep to a graphiteelectrode immersed in acid electrolyte. A maximum of 3 anodic and 3 cathodic peaks were observed in these curves depending on the experimentalconditions. The anodic peaks in the potential ran
The gasification rate of Great Lakes H-440 graphite was studied using either CO, or H,O as the reactant, while at the same time applying varying compressive stresses to the samples of up to 10% of the compressive strength. The concentrations of reaction products were continuously monitored using hig
