Green method for preparing butanol and octanol by hydrogenation catalyst

[0026] The preparation method of the monoatomic palladium catalyst is as follows: take 100ml of deionized water and place it on the bottom of the stirred reactor and heat it to 70°C, add 10ml of sodium sulfate solution, add 20g of aluminum sulfate while continuing to stir, and test that the pH reaches 4.2 to stop feeding. Aged overnight at room temperature; after filtration, washing, molding, and drying, spherical Al 2 o 3 Carrier; weigh 10g of prepared spherical Al 2 o 3 Put the carrier into a 400ml quartz beaker, add 200ml deionized water and 10ml ethylene glycol solution, stir ultrasonically for 15min, add 0.1g palladium chloride solution, turn on the xenon light source and directly irradiate the quartz beaker for 1h, wash with deionized water, and centrifuge for 3 and drying at 30° C. for 3 h to obtain the single-atom palladium catalyst.

[0030] The preparation method of the monoatomic palladium catalyst is as follows: take 100ml of deionized water and place it on the bottom of the stirred reactor and heat it to 80°C, add 10ml of sodium sulfate solution, add 20g of aluminum sulfate while continuing to stir, and test that the pH reaches 3.8 to stop feeding. Aged overnight at room temperature; after filtration, washing, molding, and drying, spherical Al 2 o 3 Carrier; weigh 1.5g of the prepared carrier and put it into a 400ml quartz beaker, then add 200ml deionized water and 10ml ethylene glycol solution, stir ultrasonically for 15min, add 0.12g palladium chloride solution, turn on the xenon lamp light source and directly irradiate the quartz beaker for 1h, use Wash with deionized water, centrifuge three times, and dry at 30° C. for 3 hours to obtain the single-atom palladium catalyst.

[0034] The preparation method of the monoatomic palladium catalyst is as follows: take 100ml of deionized water and place it on the bottom of the stirring reactor and heat it to 80°C, add 10ml of sodium sulfate solution, add 20g of aluminum sulfate while continuing to stir, and stop feeding when the test pH reaches 3.6. Aged overnight at room temperature; after filtration, washing, molding, and drying, spherical Al 2 o 3 Carrier; weigh 1.5g of the prepared carrier and put it into a 400ml quartz beaker, then add 200ml deionized water and 10ml ethylene glycol solution, stir ultrasonically for 15min, add 0.12g palladium chloride solution, turn on the xenon lamp light source and directly irradiate the quartz beaker for 1h, use Wash with deionized water, centrifuge three times, and dry at 30° C. for 3 hours to obtain the single-atom palladium catalyst.
