英文摘要 | dense planar ba0.15ce0.85feo3-delta(bcf1585) membrane reactors were investigated to produce syngas from methane. firstly, the membrane itself catalytic activity to methane was investigated using a blank bcf1585 without any catalysts. then a lilani vertical bar gamma-al2o3 catalyst was packed on the bcf1585 membrane surface to test the synergetic effects of the membrane and catalyst. it was found that the membrane itself has a poor catalytic activity to methane. the main products are co2 and c-2, and methane conversion is low due to the low oxygen permeation flux. however, after the catalyst was packed on the membrane surface, both methane conversion and oxygen permeation flux were greatly improved by the synergetic effect between the membrane and catalyst. carbon monoxide selectivity reached at 96% with methane conversion of up to 96%. the oxygen permeation flux reached at 3.0 ml/cm(2) stop min at 850 degrees c for a 1.5 mm disk membrane and can effectively be increased by reducing the thickness of the membranes. after operation for 140 h at 850 degrees c, the used membrane was examined with sem and edxs. the results revealed that the decomposition of the membrane materials could not be avoided under such conditions. oxygen partial pressure gradient across the membranes is suggested as a critical factor to accelerate the kinetic decomposition of the materials. |
