Jh. Lee et Nr. Foster, DIRECT PARTIAL OXIDATION OF METHANE TO METHANOL IN SUPERCRITICAL WATER, The Journal of supercritical fluids, 9(2), 1996, pp. 99-105
The direct partial oxidation of methane to methanol in supercritical w
ater has been investigated in an isothermal, laminar reactor over the
temperature range of 400 to 450 degrees C at 250 bar. Methane was main
ly oxidized to CO, CO2, CH3OH, and H-2. The highest selectivity to met
hanol obtained was approximately 35% with methane conversion of 1-3% a
t 400-410 degrees C. Since oxygen was the rate-limiting species, the r
eaction kinetics were determined on the basis of oxygen concentration.
