The temperature-programmed desorption (TPD) chromatograms of propylene from platinum black comprised four peaks: A, B, C, and D, with peak maxima at about 260, 380, 570, and higher than 720 K respectively. Peaks A and B were identified as the mixtures of propylene and propane. Peaks C and D were methane formed from chemisorbed propylene by decomposition as the temperature was raised during the subsequent TPD. The reactivities of various types of chemisorbed hydrogen previously detected by TPD were also investigated with regard to the hydrogenation of propylene. Two types of chemisorbed hydrogen, presumed to be present on the surface in the form of hydrogen atoms chemisorbed on top of platinum atoms and in the bridge form of molecular hydrogen, were found to react with propylene.
