Abstract
A fuel deoxygenation system includes an oxygen permeable membrane having a porous membrane and an oleophobic layer. The porous membrane has pores that create a passage extending from a first side to an opposite second side of the porous membrane. The pores have an average pore diameter less than or equal to about 0.06 microns. The oleophobic layer and the porous membrane allow oxygen to cross the oxygen permeable membrane but substantially prevent fuel from crossing the oxygen permeable membrane. A method for removing dissolved oxygen from a fuel includes delivering fuel to an oxygen permeable membrane and removing oxygen from the fuel using the oxygen permeable membrane. A method for modifying a surface of a porous membrane includes depositing an oleophobic treatment agent on the porous membrane, removing solvent and heating the porous membrane to form an oleophobic layer on the porous membrane.
