In-situ synthesis of a zeolite with encapsulated Pt was conducted to prepare a sulfur-resistant noble metal catalyst based on concepts of shape selectivity and hydrogen spillover. The prepared zeolite was of the sodalite type, in which the pore openings allow H(2) to enter the pores but not H2S. Chemisorption with H(2)/CO was conducted to verify the most of Pt atoms distribution in the cage of Pt/SOD prepared by hydrothermal method. The catalyst was tested for hydrogenation activity using light cycle oil with high contents of multi-ring aromatics and sulfur. The catalyst showed reasonable hydrogenation activity even at high levels of sulfur.
