SYNTHESIS GAS PRODUCTION BY ION TRANSPORT MEMBRANES

摘要

Synthesis gas is produced from a methane-containing reactant gas in a mixed conducting membrane reactor in which the reactor is operated to maintain the pro duct gas outlet temperature above the reactant gas feed temperature wherein the total gas pressure on the oxidant side of the membrane is less than the total gas pressure on the reactant side of the membrane. Preferably, the reactant gas feed temperature is below a maximum threshold temperature of about 1400.degree.F (760.degree.C) and typica lly is between about 950.degree.F (510.degree.C) and about 1400.degree.F (760.degree.C). The ma ximum temperature on the reactant side of the membrane reactor is greater than about 1500.degree.F (815.d egree.C).
