reforming of hydrocarbons

Steam reforming of hydrocarbons is one way to make hydrogen gas (H2) for fuel cells. However, the product gas contains H2 contaminated with carbon monoxide (CO), which must be further enriched in H2 in order for the fuel cell to work better. It is desired to separate a mixture of CO and H2 using a microporous ceramic membrane. The average pore diameter of the porous membrane material is 15 nm, and the void fraction ε = 0:10. The system operates at 5.0 atm total system pressure and 400°C.

Determine the effective diffusion coefficient of CO in the gas mixture within the microporous membrane. Is Knudsen diffusion important? You may assume that the CO is dilute in the gas mixture.
