A series of platinum were supported on a crystalline pure SAPO-11 by different loading methods; ethylene glycol reduction (EG) method and conventional incipient wetness impregnation (IM) technique. Effects of loading method and amount of platinum on the hydroisomerization of n-hexadecane in fixed bed-reactor were investigated. N 2 ad/desorption, XRD, NH 3 -TPD, H 2 -chemisorption and FE-SEM techniques were employed to study the effects of different preparation methods on the physicochemical and morphological characterization of the prepared samples. The results suggest that the Pt metal particles on the catalyst prepared by (IM) method can be located near the micropore mouth of SAPO-11 support, while the Pt sites on the catalyst prepared by EG method mainly located on the external surface. The 5 wt% Pt (EG)/SAPO-11 catalyst exhibited the best isomerization activity and yield at smaller reaction temperature (300 °C) in the hydroisomerization of n-hexadecane, which is attributed to preferential location of Pt metal particles as it was assessed that the (de)hydrogenation activity function operated by Pt metal particles is a limiting step in the catalytic performance towards improving the isomerization activity of Pt/SAPO-11 catalysts prepared by different methods.
