1. the sulfur method of a liquid gasoline fuel stream makes and changes the Fuel Petroleum logistics into low sulfur content fuel, and this low sulfur content is suitable for the fuel processing sections of fuel cell power generating system, and described method comprises following step:

  • A) provide a nickel reagent desulfurization station, its operation makes and is converted into nickelous sulfide with the contained sulphur of the form of organic sulfide in the fuel stream;

    B) described nickel reagent desulfurization station is remained on 150 ℃



    235 ℃

    temperature;

    C) at the water of described nickel reagent desulfurization station introducing 2%~

    5% and the mixture of liquid gasoline fuel stream, described mixture contains oxygenatedchemicals, amount at oxygenatedchemicals described in the described mixture can provide the logistics of low sulfur content Fuel Petroleum effectively in the exit of described nickel reagent station, and the sulphur content of this low sulfur content Fuel Petroleum logistics is not higher than 0.05ppm;

    AndD) in described desulfurized step, described oxygenatedchemicals is consumed by described nickel reagent, as long as described nickel reagent continues to consume oxygenatedchemicals, just can form the logistics of described low sulfur content Fuel Petroleum, wherein said oxygenatedchemicals is selected from water, methyl alcohol, ethanol, methyl tert-butyl ether or its mixture.
