Embodiment 1
[0022] S1: Incorporate nano-CaCO 3 , Nano Fe 2 o 3 Mix it with nano-ZnO at a molar ratio of 5.7:3.4:1, and put 3 times the volume of water into the mixture, heat it in a water bath and keep the temperature at 80°C, and stir thoroughly for 20 minutes to obtain the first product;
[0023] S2: Add 30 g of stearic acid, 15 g of trimethyl borate, 5 g of NaOH and 20 g of Fischer-Tropsch wax to the first product of 50 g of S1, and obtain the second product after stirring at a stirring speed of 1350 r / s for 30 min. product;
[0024] S3: Pour the second product of S2 into the surface of the suction filter for suction filtration, and rinse it with pure water three times during suction filtration to obtain the third product;
[0025] S4: put the third product into a drying oven for drying, the drying temperature is 110°C, and the drying time is 4 hours to obtain the precursor;
[0026] S5: Put the precursor into a grinder to grind, filter and screen the product with a particle size o...
