Conversions of ethylene on a silver membrane catalyst

1. Oxygen diffusing through a silver membrane catalyst is more active in the formation of products of the complete oxidation of ethylene than oxygen introduced in a mixture with ethylene. 2. The permeability of silver to oxygen passes through a minimum with increasing ethylene pressure at the output surface of the silver membrane and reaches a value equal to the permeability in the case of diffusion into vacuum. © 1976 Plenum Publishing Corporation.
