  • Method for removing sulfur-containing impurities from hydrocarbons
    Patent number: 4610780
    Abstract: A process is disclosed for removing sulfur-containing impurities from a liquid hydrocarbon stream wherein the optimum performance of a sulfur-removing material is achieved by selecting a material having a porosity which varies with the following formula:(0.23.+-.K)(LHSV).sup.1.7 RF.sup.2whereinK=0.12-1.55R;(LHSV) is liquid hourly space velocity;R is the ratio of volume-to-surface area of the sulfur-removing material; andF is a fraction of impurities removed divided by the total impurities of the inlet stream.
