Abstract
The comparative studies of the catalytic properties in the dehydrogenation of propane were carried out at 500-600°C and atmospheric pressure using the catalysts derived from different Pt - Sn clusters {[PtCl (SnCl3) (PPh3)2], (Me4N)2[(PtCl2(SnCl3)2] and (Me4N)3[Pt(SnCIa)5]) and the conventional Pt - Sn catalysts prepared from H2PtCl6 and SnCl2 with different Sn/Pt ratios (Sn/Pt = 1 : 1,2 : 1, 5 : 1), The results showed that Sn introduced in the catalysts inhibited the hydrocracking activities, but increased the dehydrogenation activities of propane. Moreover, the higher the content of Sn was in the catalyst (in the range of Sn/Pt ratio 1 to 5), the lower the hydrocracking activities were exhibited. Comparing two types of Pt - Sn catalysts, it is obvious that the activities, selectivities to propene and the stabilities of catalysts derived from Pt - Sn clusters, except the catalyst prepared from [PtCl (SnCl3) (PPh3)2], were higher than that of the conventional Pt - Sn catalysts. This suggested that Sn in the catalysts derived from Pt - Sn clusters exhibited stronger modification for the catalytic properties of Pt and was more favourable for the Pt dispersion on a-lumina surface. Therefore, the coking and sintering on the catalyst surface were greatly decreased.
