KINETICS OF THE CATALYZED OXIDATION OF HYDROGEN, CARBON MONOXIDE, AND METHANE BY OXYGEN IN A FLOWING STREAM OF HELIUM

摘要

Data from kinetic tests on the oxidation by oxygen catalyzed by a fixed bed of Girdler G-43 platinum catalyst of hydrogen, carbon monoxide, and methane, in a flowing stream of helium, were empirically correlated to give reactor design equations for use in design of catalytic oxidizers for gas-cooled reactor helium purification systems. A typical design for the EGCR purification system was a catalytic oxidizer with 3.77 ft of catalyst. All tests were made in a 2-in.-dia reactor at an average tem-perature of 500 ± 25℃, a total pressure of 300 psia, mass flow rates of 0.066 to 0.225 g mole/cm2 min, and contaminant levels of 0.219 to 2.00 vol ％.
