The invention provides an optimum method for utilizing a desulfurizing agent for liquid hydrocarbons which can efficiently remove sulfur content from kerosene without performing addition of hydrogen to a low sulfur concentration and which has a prolonged lifetime. The invention provides a desulfurization method which includes removing sulfur content from kerosene by use of a metallic desulfurizing agent without performing addition of hydrogen, characterized in that the method employs desulfurization conditions satisfying the following formula (1): 1.06×Pope0.44<Tope/T50<1.78×Pope0.22 (1) (wherein Tope is operation temperature (° C.); Pope is operation pressure (MPa); and T50 is a temperature per 50 percent recovered as determined by “test method for distillation at atmospheric pressure” stipulated in JIS K2254 “Petroleum products—Determination of distillation characteristics”).
A desulfurization method comprising removing sulfur content from a liquid hydrocarbon with a metallic desulfurizing agent, wherein said method employs desulfurization conditions satisfying the following formula (1):
A method for producing a desulfurized liquid hydrocarbon, said method comprising removing sulfur content from a liquid hydrocarbon with a metallic desulfurizing agent to produce said desulfurized liquid hydrocarbon, wherein said method employs desulfurization conditions satisfying the following formula (1):
