Determination of a Kinetic Rate Expression for the Oxidation of Chloroform Over a 2% Platinum/Alpha-Alumina Catalyst
Abstract
The complete catalytic oxidation of chloroform over a 2% platinum/alpha-alumina catalyst was investigated using a fixed bed catalytic reactor at temperatures between 300 and 400 deg C, atmospheric pressure, and concentrations ranging from 100 ppm (533 mg/m 3) to 5,050 ppm (26,898 mg/m3) in humid air. A kinetic rate expression was developed to describe the data over the range of conditions investigated. The rate expression included terms for inhibition due to both the reactant chloroform and acid gas reaction product. Deactivation of the catalyst by chloroform was minimal at reaction temperatures of 400 deg C and below; however, at 450 deg C, catalytic deactivation was significant.
