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 c'yclohexane for the two catalysts were calculated. The determination of the total numbers of active sites (TNAS) for the catalysts shows that Y makes 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.
Keywords:Reforming  Yttrium  Poisoning of catalyst
