Oxygen carrier composition and preparation method thereof

[0022] A preparation method of an oxygen carrier composition, comprising the steps of:

[0023] Step 1, add aluminum hydroxide to absolute ethanol (1L), stir evenly, then add polyvinylpyrrolidone and ultrasonically disperse completely at low temperature to obtain a uniform dispersion; the concentration of aluminum hydroxide in absolute ethanol is 100g / L , the stirring speed is 1000r / min, the addition of the polyvinylpyrrolidone is 30% of the mass of aluminum hydroxide, the temperature of low-temperature ultrasonic dispersion is 20°C, and the ultrasonic frequency is 50kHz,

[0024] Step 2: Add the uniform dispersion liquid into the mold for constant temperature extrusion, then soak it in absolute ethanol, stir evenly, and dry to obtain a porous body. The temperature of the constant temperature extrusion is 80°C, the pressure is 2MPa, and the uniform stirring The speed is 1000r / min, the drying temperature is 80°C, and the particle size of the porous body particles is 3mm;
