Abstract:
1. A method for adsorptive removal of sulfur from a hydrocarbon stream, the method comprising contacting said hydrocarbon stream with an adsorbent composition under conditions sufficient to achieve a single-pass adsorption capacity for sulfur compounds of more than 1.6 grams of sulfur compounds per 100 grams of the adsorbent composition, the adsorbent composition comprising: a nanocrystal complex comprised of approximately 2-10 nm sized crystals of elemental Ni having associated therewith a plurality of chemical moieties selected from the group consisting of elemental phosphorus, phosphine moieties (PH x ), and combinations thereof, wherein said nanocrystal complex exhibits a molar ratio of P to Ni from about 0.2 to about 0.6, and a refractory support material comprising micro-mesoporous silica, mesoporous silica, meso-structured silica, alumina, and mixtures and combinations thereof; said adsorbent composition made by a process comprising: a) providing the refractory support material; b) depositing on said support material a combination of nickel oxide and one or more Ni c) reducing said combination of nickel oxide and Ni
