Abstract

Abstract

Noble metals are widely used as hydrogenation catalysts for refining and modifying fuel oil. However, their stability is still a problem. Thus, crystal transformation method was used here to encapsulate platinum (Pt) particles in sodalite through two steps. First, the sample was crystallized at 100 ℃ for 12 h. Then, it was further crystallized at 120 ℃ for 144 h, 130 ℃ for 96 h, 140 ℃ for 60 h, 150 ℃ for 42 h, or 160 ℃ for 30 h. The resultant solid (designated as Pt/SOD) shows high activity and excellent sulfur-tolerant performance in benzene hydrogenation. The crystalline phases were identified by X-ray diffraction technique. The hydrogen spillover effect of Pt/SOD and the spillover hydrogen acceptability of HZSM-5 were investigated with H₂-TPD.
