Embodiment 1
[0017] Solution 1: 0.02mol K4Fe(CN)6·3H2O was dissolved in 80ml double distilled water to prepare 0.25mol / l solution 1.
[0018] Solution 2: Dissolve 0.2 mol metal chloride salt (ZnCl2) in 20 ml tert-butanol and 20 ml double distilled water (add a small amount of HCl to avoid flocculent precipitation) to prepare 5 mol / l solution 2.
[0019] Solution 3: Dissolve 30 g of polyethylene glycol 4000 in 4 ml of water and 80 ml of tert-butanol at a ratio of 30:4:80 (g / ml / ml).
[0020] The solution 1 obtained above was slowly added dropwise to the solution 2 at 323K to form a precipitate, and magnetic stirring was carried out at the same time. Then solution 3 was added within 5-10 min, and stirring was continued for 2 h. filter. Wash 3-5 times with water (500ml of water each time). 313K vacuum drying to obtain a bimetallic solid catalyst.
[0021] The catalytic activity of the bimetallic solid catalyst was evaluated using rapeseed oil containing 10wt% free fatty acid and 10wt% mois...
Embodiment 2
[0026] Solution 1: 0.015mol K4Fe(CN)6·3H2O was dissolved in 60ml double distilled water to prepare 0.25mol / l solution 1.
[0027] Solution 2: Dissolve 0.2 mol metal chloride salt (ZnCl2) in 40 ml tert-butanol and 40 ml double distilled water (add a small amount of HCl to avoid flocculent precipitation) to prepare 5 mol / l solution 2.
[0028] Solution 3: Dissolve 20 g of polyethylene glycol 4000 in 4 ml of water and 60 ml of tert-butanol at a ratio of 20:4:60 (g / ml / ml).
[0029] The solution 1 obtained above was slowly added dropwise to the solution 2 at 323K to form a precipitate, and magnetic stirring was carried out at the same time. Then solution 3 was added within 5-10 min, and stirring was continued for 2 h. filter. Wash 3-5 times with water (500ml of water each time). 313K vacuum drying to obtain a bimetallic solid catalyst.
[0030] The catalytic activity of the bimetallic solid catalyst was evaluated using rapeseed oil containing 10wt% free fatty acid and 10wt% moi...
Embodiment 3
[0035] Solution 1: 0.025mol K4Fe(CN)6·3H2O was dissolved in 100ml double distilled water to prepare 0.25mol / l solution 1.
[0036] Solution 2: Dissolve 0.4 mol metal chloride salt (ZnCl2) in 20 ml tert-butanol and 20 ml double distilled water (add a small amount of HCl to avoid flocculent precipitation) to prepare 5 mol / l solution 2.
[0037] Solution 3: Dissolve 60 g of polyethylene glycol 4000 in 4 ml of water and 100 ml of tert-butanol at a ratio of 60:4:100 (g / ml / ml) to obtain 120 ml of a solution.
[0038] The solution 1 obtained above was slowly added dropwise to the solution 2 at 323K to form a precipitate, and magnetic stirring was carried out at the same time. Then add solution 3 within 5-l0min and continue stirring for 2h. filter. Wash 3-5 times with water (500ml of water each time). 313K vacuum drying to obtain a bimetallic solid catalyst.
[0039] The catalytic activity of the bimetallic solid catalyst was evaluated using rapeseed oil containing 10wt% free fatt...
