The present invention is a method for removing sulfur from hydrocarbon feedstocks and for performing hydrogenation reactions in sulfur-contaminated feedstocks, including the hydrogenation of naphthalene in the presence of sulfur compounds, using catalysts or adsorbents comprising metal oxide nanowires decorated with reduced catalytically-active metal particles. In an exemplary embodiment, the adsorbent comprises zinc oxide nanowires decorated with catalytically-active metals selected from nickel, cobalt, molybdenum, platinum, palladium, copper, oxides thereof, alloys thereof, and combinations thereof. In some embodiments, the sulfur is removed through a desulfurization process without an external hydrogen supply. The process is effective for the removal of sulfur from diesel fuels and liquid fuel streams, and for deep desulfurization of natural gas streams. The process is also effective for the selective hydrogenation of naphthalene to tetralin in the presence of sulfur compounds.

A hydrogenation catalyst and a preparation method therefor and the use thereof, and a hydrogenation reaction method for oil products are presented. The hydrogenation catalyst is a sulfurized hydrogenation catalyst and comprises a carrier, a molecular sieve and an active component, wherein the active component comprises at least one of group VIII metal elements and at least one of group VIB metal elements, and is characterized by using a TEM-EDS method. On the basis of the silicon element, the ratio of the amount of the molecular sieve directly acting on a group VIB metal sulfide to the total amount of the molecular sieve is 60-100%. The hydrogenation catalyst provided in the present invention can control a polycyclic aromatic hydrocarbon to realize ring opening without chain scission, generating a monocyclic aromatic hydrocarbon with a long-branched chain, which can be used as both an ethylene cracking raw material and a diesel product.
