Non-uniform Distribution of Membrane Permeability

The scenario occurring in a porous MR with a homogeneous porous membrane as the O2 distributor for the partial oxidation of alkane is 

A chemical valve membrane with permeability controlled by the redox properties of the gas phase has been proposed to better regulate the O2 flux in the reactor [17], It can be prepared by depositing V2O5 and AIPO4 crystallites inside the pores of a tubular a-Al203 substrate. The reversible
