Example Embodiment
[0024] Example 1
[0025] Weigh 40 g of diesel oil, add 0.9 g of organic bentonite (Jiangsu Huate New Material Company, the mass fraction of organic matter is 15-20%), and homogenize on a shearing machine. Then heat and stir on an oil bath at 60° C. for 2 hours, add 0.5 g of analytically pure ethylene glycol, stir until homogeneous, and then cool to room temperature to obtain dispersion medium A.
Example Embodiment
[0026] Example 2
[0027] Weigh 38 g of kerosene, add 0.8 g of fumed silica (with a particle size of less than 1 μm), and homogenize with a shearing machine. Then, it was heated and stirred on an oil bath at 50° C. for 2 hours, 0.2 g of glycerol was added, stirred to a homogeneous phase, and then cooled to room temperature to obtain dispersion medium B.
Example Embodiment
[0028] Example 3
[0029] Take the limonite ore powder whose average particle size is less than 20 μm, weigh 6.0 g and place it in a test tube. Weigh 12.0 g of Dispersing Medium A in the same test tube, stir and shake the glass rod, and let it stand for 6 hours after the powder is evenly infiltrated without significant sedimentation. A catalyst C1 was obtained.
