Two-Surface Virial Analysis Of Alkane Adsorption On Carbopack C With And Without Hydrogen Treatment., Chrystal Bruce, Thomas Rybolt, Howard Thomas, Tara Agnew, Brandon Davis
Chrystal D. Bruce
Second gas–solid virial coefficients for propane, butane, pentane, and hexane were found for Carbopack C and Carbopack C-HT (Supelco Inc.) within the temperature range of 323 to 471 K using gas–solid chromatography in the Henry's law region of adsorption. Carbopack C and Carbopack C-HT are both graphitized carbon black powders. Treatment of Carbopack C with hydrogen at 1273 K converts it to Carbopack C-HT and is believed to remove certain high energy sites or “hot spots” from the carbon surface. These two surfaces provide appropriate model systems to test a two-surface virial analysis. Surface areas for both powders were calculated …
