摘要： 铂铼、铂锡、铂铱等双金属催化剂已有报道,但有关以稀土金属为第2或第3组分的重整催化剂的报道尚很少见,本文报道用中毒法对PtY/Al2O3的金属活性中心性质的研究,试图探讨其活性中心与催化性质的某些联系。

Abstract: The catalytic reforming and active site properties for Pt/Al2O3 and PtY/Al2O3 were studied by using pulse microcatalytic reactor, TEM and poisoning technnique. The kinetic data of dehydro-genation of cyclohexane for the two catalysts were calculated. The determination of the total numbers of active sites (TNAS) for the catalysts shows that Ymakes TNAS increase. The correlation of the catalytic behavior with the particle size and the properties of active sites for the two catalysts has also been discussed here.
