Simple Syngas Detector for High-throuput Screening Reactor Using Color Reaction at High Pressure

Abstract

The high-throughput screening reactor for high pressure oxidative reforming of methane requires a new simple syngas detector operating under high pressure, because the number of parallel reactors with the conventional detection system is limited by the complexity of the pressure reducing unit. Reduction of metal oxide with color change was applied to the detection system. Copper oxide was supported on the filter made of alumina, and the filter was placed underneath the catalyst bed. After oxidative reforming of methane was carried out under 1 MPa at 650°C, color change of spots from dark brown to light brown was observed just under the catalyst caused by copper oxide reduction. The color change disk can be used to detect hydrogen formation ability of the reforming catalyst under pressure.
