1. preparation very low-sulfur, very low aromatic hydrocarbon fluid method, the hydrocarbon fluid contains the sulphur less than 5ppmAnd have lower than the aromatic content of 50ppm, the naphthene content of 44.3-55.8 weight %, 30.2-38.2 weight %Isoparaffin content, the normal paraffin content of 13.9-17.5 weight %, boiling and having in the range of 100-400 DEG C does not surpass80 DEG C of boiling range is crossed, the method includes at least following two successive steps:

  • By middle distillate deep hydrodesulfurizationof to less than the sulphur of 10ppm, the deep hydrodesulfurizationof is in fixed bed reactorsIt is real under the pressure higher than 70 bars and the reaction temperature changed between 320 and 370 DEG C in the presence of Hydrobon catalystIt applies, andBy the middle distillate through desulfurization of abovementioned steps 80-180 DEG C at a temperature of and under 60-160 bars of pressure with containingRaney nickel carries out catalytic hydrogenation,The wherein middle distillate;

    A) it is generated by air-distillation unit outflow object, orB) it is generated by air-distillation unit and catalytic cracking effluent,Such distillate boils in the range of 180 DEG C -400 DEG C, and the middle distillate contains the aromatics less than 70%Close object.
