A proposed new concept for design of sulfur-resistant noble metal catalysts based on shape-selective exclusion and hydrogen spillover

The aims of this article are to briefly discuss the present understanding of the way in which noble metal catalysts are used for fuel hydrogenation, and to propose a new way of thinking for designing noble metal catalysts for low-temperature hydrotreating. A new concept is proposed for design of sulfur-resistant noble metal catalysts for hydrotreating at low temperatures on the basis of shape-selective exclusion, hydrogen spillover, and differentiation of sulfur resistance.
