Notes:
Pulse gas chromatography experiments at ambient pressure are often limited by an overwhelming contribution of axial dispersion to the observed variance and the inability to obtain a quantitative correction for this factor. Theoretically, the axial dispersion contribution can be reduced and at the same time the contribution due to particle diffusion can be enhanced by operating at elevated pressures. Our experiments on methane/helium diffusion in 0.32-cm-diameter commercial catalyst particles confirm this, and a new means of accounting for axial dispersion is demonstrated.
