Abstract
PURPOSE: To determine CO with a catalyst oxidizing CO even at ordinary temp. and elevated humidity and causing no sorption of CO2 by allowing a kneaded and molded body of alkali, a cementing agent and powdered activated carbon to support Pd or Pd and one or more kinds among Pt, Rh and Ru.
CONSTITUTION: An oxidation catalyst for determining CO in exhaust gas by oxidation to CO2 is prepared as follows: 10wt% K2CO3 as alkali, 60wt% alumina cement or the like as a cementing agent and 30wt% powdered activated carbon are kneaded with a small amount of a binder such as 0.5% CMC and water, molded, dried, pulverized, and classified. The resulting material is then allowed to simultaneously support 0.3wt% one or more kinds among Pt, Rh and Ru and 0.3wt% Pd and reduced with NaBH4. This catalyst can oxidize CO to CO2 even in the presence of moisture. It does not oxidize hydrocarbon coexisting with CO at ≤150°C and causes no sorption of CO2 at room temp. Accordingly, it is not required to refrigerate a sample to a low temp. with liq. air before passing through the catalyst. The catalyst is heated to ≤150°C. Thus, an analyzed value is obtd. correctly.
