Dehydrogenation of Methylcyclohexane over Pt-Co-La Catalysts Supported on Pyrolytic Waste Tire Char

Abstract In the present work, the Pt-Co-La catalysts supported on pyrolytic waste tire char (PTC) were prepared by impregnation method. The loading of Pt is 0.2%, Pt-Co-La atomic ratio is 1∶1:x (x=1—4). The characterization of N₂adsorptiondesorption, H₂-TPR and pulse CO chemisorption results showed that the addition of a moderate amount of La to the Pt-Co bimetallic catalyst was beneficial to reduce Pt and Co, and improve their dispersion. The activity of the catalysts for dehydrogenation of methylcyclohexane（MCH）at 300 ℃ was investigated. The results suggest that trimetallic catalysts 1Pt-1Co-xLa/PTC(x=1—3) exhibited the high activity, compared with Pt, Pt-Co and Pt-La supported on PTC.
