Abstract

Effects of loading method and amount of platinum on the hydroisomerization of n-dodecane were investigated. Platinum was supported on SAPO-11 by incipient wetness, ion exchange, or atomic layer deposition. Characterization of catalysts was carried out using N2 adsorption, XRD, NH-TPD, TPR, and pyridine-IR. The dispersion of the Pt (IE 0.2)/SAPO-11 and the Pt (ALD 0.6)/SAPO-11 are 0.65 and 0.59, respectively, which are much higher than those of the catalysts prepared by incipient wetness method. The Pt(IW)/SAPO-11 catalyst exhibited the best isomerization activity in the hydroisomerization of n-dodecane, which is attributed to the highest reducibility.
