Gas flow through porous barriers
In Part I the possibility of CO/sub 2/ surface diffusion through the porous BaO that results from BaCO/sub 3/ decomposition is examined. CO/sub 2/ and He flow rates through a BaO barrier are compared and both are found to exhibit similar behavior. Because He is known not to undergo surface diffusion, it is concluded that CO/sub 2/ goes through BaO by ordinary Knudsen flow. In Part II the decomposition of SO/sub 3/ to SO/sub 2/ and O/sub 2/ in a porous alumina barrier is studied. The goal is to determine if this reaction will equilibrate in the barrier. A stream of SO/sub 3/ is run through the barrier and the exit gas compositions are determined as a function of temperature with a mass spectrometer. These compositions are found to differ considerably from the calculated equilibrium values, indicating the reaction does not equilibrate in the barrier.
