摘要: Abstract Results of hydrogen production study in methanol steam reforming (MSR) process with the use Ru0.5–Rh0.5 catalysts supported on different carbon materials: synthetic graphite-like material Sibunit, black Ketjenblack EC600DJ, detonation nanodiamonds (DND) and ZrO2-based fluorite structure, doped ceria, have been described. The samples tested conventional flow reactor membrane (MR) reactor, containing Pd-based membranes composition, thickness surface architecture. It has shown that catalytic activity composites depends support nature. Ru Rh/DND catalyst exhibits highest activity, whereas Rh/Ce0.1Zr0.9O2–δ is most selective. Pd Ag (23%) foil modified by palladium showed great advantages comparing to smooth dense membrane. MR improves MSR reaction provides almost 50% increase yield. produced ultra pure.
