Abstract:
A catalyst and its use for selectively desulfurizing sulfur compounds present in an olefin-containing hydrocarbon feedstock to very low levels with minimal hydrogenation of olefins. The catalyst comprises an inorganic oxide substrate containing a nickel compound, a molybdenum compound and optionally a phosphorus compound, that is overlaid with a molybdenum compound and a cobalt compound. The catalyst is further characterized as having a bimodal pore size distribution with a large portion of its total pore volume contained in pores having a diameter less than 250 angstroms and in pores having a diameter greater than 1000 angstroms.

Claim (Index 1):
A process for selectively hydrodesulfurizing sulfur compounds contained in an olefin-containing hydrocarbon feedstock with minimal hydrogenation of olefins, which process comprises:\n contacting in a reactor under selective hydrodesulfurization conditions said olefin-containing hydrocarbon feedstock with a calcined catalyst particle made by calcining a shaped particle of a mixture comprising an inorganic oxide support material, molybdenum trioxide and a nickel compound to provide a calcined shaped particle; wherein said calcined shaped particle is further overlaid with a cobalt compound and a molybdenum compound and is subjected to a further calcination step to produce said calcined catalyst particle, said calcined catalyst particle being characterized by having a bimodal pore size distribution with at least 20% of the total pore volume being in pores having a diameter less than 250 angstroms and at least 10% of the total pore volume being in pores having a diameter greater than 1000 angstroms.
