The experimental apparatus first used in pulse-injection experiments was described by Yao and Yu Yao, while schematic diagrams of it were reported by Su etalj Engler etal and Duprez and Descorne. In a characteristic CO pulse-injection experiment, the catalyst sample (typically 10-50 mg) is placed in a quartz tubular or U-tube-type microreactor kept at a given reaction temperature. A carrier gas (e.g.. He or Ar) is used at flow rates within the 30-200 cm -min" range to sweep the pulse through the catalytic microreactor.
