Embodiment 1
[0029] Weigh 40 g of diesel oil, add 1.2 g of organic bentonite (Jiangsu Huate New Material Co., Ltd., the mass fraction of organic matter is 20-35%), and homogenize with a shearing machine. Then, 1.2 g of oleic acid was added, followed by heating and stirring on an 80° C. oil bath for 2 hours. The obtained homogeneous mixed oil was cooled to room temperature, 0.5 g of PEG 600 was added, and 0.2 g of sodium dodecylbenzenesulfonate was added, and stirred at a high speed at room temperature to obtain dispersion medium A.
Embodiment 2
[0031] Weigh 36g of kerosene, add 1.0g of organic bentonite (Jiangsu Huate New Material Co., Ltd., the mass fraction of organic matter is 20-35%), and homogenize with a shearing machine. Then 1.2 g of oleic acid was added, heated and stirred in an oil bath at 80° C. for 2 hours. At room temperature, 0.2 g of sodium oleate and 0.4 g of PEG2000 were added. Stir evenly at high speed at room temperature to obtain dispersion medium B.
Embodiment 3
[0033] Take pyrite powder whose average particle size is less than 40 μm, weigh 5.0 g and place it in a test tube. Weigh 10.0g of dispersion medium A into the same test tube, stir and vibrate with a glass rod, after the powder is evenly infiltrated, let it stand for 12 hours without obvious sedimentation. Catalyst C1 is obtained.
