Abstract
Methylcyclohexane (MCH) is expected as a hydrogen carrier. Dehydrogenation of MCH was conducted over supported Pt catalysts at 623 K. Pt/TiO2 showed high stability for dehydrogenation and good resistance for coke formation. The partial pressure dependence of MCH, toluene, and H2 was investigated for Pt/TiO2 and Pt/Al2O3 catalysts, which showed different tendencies for toluene partial pressure. The reaction order of toluene partial pressure for Pt/TiO2 was almost zero, but that for Pt/Al2O3 was a negative value. Toluene inhibited the Pt/Al2O3 catalytic activity, but that of Pt/TiO2 was unaffected. The SMSI effect was confirmed on Pt/TiO2 by CO chemisorption measurement. Pt on TiO2 became an electron-rich state compared to Pt0 because of the electron donation from TiOx, and the toluene adsorption to Pt on TiO2 was weakened.
