Abstract

To develop an effective way to produce hydrogen continuously by means of partial oxidation of natural gas methane, we experimentally studied a Ni catalytic-permeable-membrane-tube reactor. When a mixture of CH4 and O2 was introduced into a Ni tube, H2 was produced by a partial oxidation reaction and permeated through the Ni-tube reactor to separate from another product of CO. The dependence of the partial oxidation rate on the inlet CH4/O2 molar ratio, temperature, flow rate, and total pressure were determined experimentally. The rate constants of the complete oxidation reaction, the steam-reforming one and the CO2-reforming one were simultaneously determined at temperatures of 400 to 750°C from fitting analytical calculations to experimental ones. Although complete separation between CO and H2 was not achieved within a limited surface area in the present experiment, it was analytically proved that H2 and CO can be effectively separated in a long Ni-tube reactor.
