Embodiment 1
[0036] [Production of spherical carriers]
[0037] Use nitrogen to fully ventilate the 5L glass reactor equipped with stirrer, oil heater and reflux condenser, then mix 4.5g N-chlorosuccinimide, 60g magnesium metal (average particle size is 100μm powder product) and 1000ml of absolute ethanol were added to the reactor, and then the stirrer was operated at 240rpm at a reaction temperature of 60°C. After 10 minutes, the reaction started and hydrogen was generated, the outlet of the reactor was kept open to vent the hydrogen, and the reactor was kept at normal pressure. After hydrogen evolution had ceased, the reactor was maintained at 60°C for an additional 2 hours. After keeping the reactor for 2 hours, the temperature was raised to 75°C and aged at this temperature for 2 hours. After aging, the resultant was washed three times at 50° C. with 2,000 ml of n-hexane each time. The washed resultant was dried in flowing nitrogen for 24 hours, and then 262 g of a solid product (93...

[0052] [Production of spherical carriers]
[0053] Use nitrogen to fully ventilate the 5L glass reactor equipped with stirrer, oil heater and reflux condenser, then mix 4.5g N-chlorosuccinimide, 60g magnesium metal (average particle size is 100μm powder product) and 1000ml of absolute ethanol were added to the reactor, and then the stirrer was operated at 240rpm at a reaction temperature of 45°C. After 10 minutes, the reaction started and hydrogen was generated, the outlet of the reactor was kept open to vent the hydrogen, and the reactor was kept at normal pressure. After hydrogen evolution had ceased, the reactor was maintained at 45°C for an additional 2 hours. After keeping the reactor for 2 hours, the temperature was raised to 75°C and aged at this temperature for 2 hours. After aging, the resultant was washed three times at 50° C. with 2,000 ml of n-hexane each time. The washed resultant was dried in flowing nitrogen for 24 hours, and then 265 g of a solid product (94...
