ABSTRACT:
A process for removing relatively low levels of high molecular weight organic sulfur from hydrocarbon streams, particularly from streams that have picked-up such sulfur while being transported through a pipeline. The hydrocarbon stream containing the organic sulfur is passed through a bed of adsorbent material comprised of a high Ni content, high surface area material that also contains an effective amount of SiO2or GeO2and an alkaline earth metal.
