Estimating the term…
The present invention provides a high capacity adsorbent for removing sulfur from hydrocarbon streams. The adsorbent comprises a composite material containing particles of a nickel phosphide complex NixP. The adsorbent is utilized in a sulfur removal process that does not require added hydrogen, and run at relatively low temperatures ranging from about 150° C. to about 400° C. The process of this invention enables “ultra-deep” desulfurization down to levels of about 1 ppm and less.
A method for adsorptively removing sulfur front a hydrocarbon stream containing sulfur species, the method comprising contacting said stream with a composite adsorbent comprising a nickel phosphide complex having particles of Ni2P, Ni12P5, Ni3P phase, or a mixture thereof deposited on a silica, mesoporous silica, silica-alumina, or carbon support, wherein the composite adsorbent adsorbs the sulfur species, thus forming a reduced sulfur hydrocarbon stream.
