Ambersorb

Data from tests at 250,275,300, and 325 C were used to calculate pseudo-first order rate constants for the formation of H2S. These data are expressed on a standard Arriienius plot (Fig. 2) for which the linear least squares coefficient of determination, r, is 0.98. The apparent activation energy calculated from the slope is 28.5 kcal/mol. This result is in excellent agreement with the recent work of Abotsi, who studied the performance of carbon-supported hydrodesulfurization catalysts (10). Using Ambersorb XE-348 carbon lo ed with sulfided ammonium molybdate (3% Mo loading) prepared by the same procedure reported here, Abotsi hydrotreated a coal-derived recycle solvent The apparent activation energy for...

Initial costs for Ambersorb 563 are higher than for GAC, however, savings may be reahzed after the system has been operating for approximately 18 months when the impact of lower operation and maintenance costs are felt. Cost information from a U.S. EPA SITE program demonstration in 1994 at the former Pease Air Force Base in Newington, New Hampshire, is presented in Table 1. The actual demonstration was pilot scale, with a rate of 1 gal/min (4 liters/min), but the cost data is based on a 100-gal/min (389 liters/min) extrapolation from the pilot study.
