Effect of Gas Properties on the Permeability of Fine-Pored Carbons

Abstract

The permeability of two fine-pored carbons were experimentally determined as a function of the mean pressure, temperature, temperature gradient and gas properties. The gases used in the investigation were helium, nitrogen, argon and sulfur hexafluoride. It was found that permeability is not only a function of the mean pressure, but is also dependent on the inlet pressure. Temperature gradient itself did not appreciably affect the flow. A mean temperature increase, however, was found to decrease the permeability. The application of two previously proposed models did not lead to an accurate prediction of the effect of gas properties on the flow.
