SYNTHESIS GAS PRODUCTION BY ION TRANSPORT MEMBRANES

摘要

SYNTHESIS GAS IS PRODUCED FROM A METHANE-CONTAINING REACTANT GAS (19) IN A MIXED CONDUCTING MEMBRANE REACTOR (37) IN WHICH THE REACTOR IS OPERATED TO MAINTAIN THE PRODUCT GAS OUTLET (49) TEMPERATURE ABOVE THE REACTANT GAS FEED (35) TEMPERATURE WHEREIN THE TOTAL GAS PRESSURE ON THE OXIDANT SIDE (43) OF THE MEMBRANE (47) IS LESS THAN THE TOTAL GAS PRESSURE ON THE REACTANT SIDE OF THE MEMBRANE. PREFERABLY, THE REACTANT GAS FEED (35) TEMPERATURE IS BELOW A MAXIMUM THRESHOLD TEMPERATURE OF ABOUT 1400°F (760°C), AND TYPICALLY IS BETWEEN ABOUT 950°F (510°C) AND ABOUT 1400°F (760°C). THE MAXIMUM TEMPERATURE ON THE REACTANT SIDE(45) OF THE MEMBRANE REACTOR(37) IS GREATER THAN ABOUT 1500°F (815°C).
