PROCESS FOR ADSORPTION OF SULFUR COMPOUNDS FROM HYDROCARBON STREAMS

摘要

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 Ni_xP. 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.
