Embodiment 1
[0022] (1) Rinse the pig bones with distilled water three times to remove the soluble impurities on the surface; remove the water from the processed pig bones in a blast drying box and dry them at 105°C for 13.5 hours; place the pig bones in a muffle furnace and heat After the temperature was raised to 1000°C, it was calcined for 3 hours to obtain a white bar-shaped solid. Crush the white solid, pass through a 160-180 mesh sieve to obtain a white powdery solid, which is vacuum dried and stored;
[0023] (2) Weigh a certain amount of potassium carbonate powder and dissolve it in ionized water to prepare a potassium carbonate solution with a concentration of 0.45M, add the white powdery solid to the ratio of 2.67, and stir for 4 hours under the condition of 500rpm to obtain a suspension , Dry to obtain a powdery solid;
[0024] (3) The obtained white powder was calcined in a muffle furnace at 600° C. for 4 hours to obtain a powdery biodiesel catalyst.
[0025] It can be obtained from...
Embodiment 2
[0028] (1) Rinse the pig bones with distilled water 4 times to remove the soluble impurities on the surface; remove the water from the processed pig bones in a blast drying box, and dry at 90°C for 15 hours; place the obtained pig bones in a muffle furnace After heating to 800°C, calcining for 5 hours to obtain a white bar-shaped solid. Crush the white solid, pass through a 160-180 mesh sieve to obtain a white powdery solid, which is vacuum dried and stored;
[0029] (2) Weigh a certain amount of potassium carbonate powder and dissolve it in ionized water to prepare a potassium carbonate solution with a concentration of 0.45M. Add 7g of the white powdery solid obtained, stir for 5 hours at 400rpm, and obtain a suspension. , To obtain a powdered solid;
[0030] (3) The obtained white powder was calcined in a muffle furnace at 500° C. for 4 hours to obtain a powdery biodiesel catalyst.
[0031] In order to test the catalytic activity of the catalyst, 2.4g of the catalyst, 30g of palm...
Embodiment 3
[0033] (1) Rinse the pig bones with distilled water 5 times to remove the soluble impurities on the surface; remove the water from the processed pig bones in a blast drying box, and dry them at 110°C for 12 hours; place the obtained pig bones in a muffle furnace After heating to 900°C, calcining for 4 hours to obtain a white bar-shaped solid. Crush the white solid, pass through a 160-180 mesh sieve to obtain a white powdery solid, which is vacuum dried and stored;
[0034] (2) Weigh a certain amount of potassium carbonate powder and dissolve it in ionized water to prepare a potassium carbonate solution with a concentration of 0.45M, add the white powdery solid to the ratio of 2.67, and stir for 3 hours under 600rpm to obtain a suspension , Dry to obtain a powdery solid;
[0035] (3) The obtained white powder is calcined in a muffle furnace at 700° C. for 4 hours to obtain a powdery biodiesel catalyst.
[0036] In order to test the catalytic activity of the catalyst, 2.4 g of the ca...
