[0026] Step A, the preparation of Jatropha jatropha crude oil;
[0027] Step B, carrying out ultrasonic-assisted phospholipase C degumming treatment on the Jatropha jatropha crude oil prepared in step A, after the degumming finishes, obtain the degummed Jatropha jatropha oil through centrifugation;
[0028] Step C, put the degummed jatropha oil and propylene glycol and inorganic strong base catalyst obtained in step B into a container, and fill the container with nitrogen, and discharge the air;
[0029] Step D, under the action of light waves, the degummed Jatropha oil, propylene glycol, and inorganic strong base catalyst are heated and reacted; the light wave power is 300-500W, and the duration is 1-1.5 hours;
[0030] Step E, stop heating, cool the reactant to room temperature, stir under the protection of nitrogen, add strong acid to reduce the pH of the reaction material to 4-5;
[0031] Step F, transfer the reaction material to a liquid separation vessel, let it stand f...
Embodiment 1
[0034] Select Jatropha jatropha fruits, remove the deteriorated Jatropha jatropha fruits and foreign matter, so that the impurity content is ≤2%; soak the selected Jatropha jatropha fruits in 0.6% dilute lye at 50°C for not less than 30 minutes, and then immerse them in cold water Rinse the jatropha fruit; then dry the peeled jatropha fruit and press it in an extruder at room temperature. The walnut kernels are divided into 15KG bags and put into the mold of the extruder. Separation of slices; pressing adopts segmental boosting method, the pressure of the pre-pressing section with a pressure of 10MPa is boosted at a speed of 4MPa / min, and the pressure is raised to 40MPa to release the pressure and discharge; the squeezed jatropha oil is filtered to remove slag or Centrifuge and remove slag to obtain crude oil a and oil residue, oil residue reclaims crude oil b by press filtration, mixes crude oil b with crude oil a, obtains Jatropha crude oil; heats the obtained Jatropha crude ...
Embodiment 2
[0037] Select Jatropha jatropha fruits, remove the deteriorated Jatropha jatropha fruits and foreign matter, so that the impurity content is ≤2%; soak the selected Jatropha jatropha fruits in 0.5% dilute lye at 60°C for not less than 30 minutes, and then immerse them in cold water Rinse the jatropha fruit; then dry the peeled jatropha fruit and press it in an extruder at room temperature. The walnut kernels are divided into 18KG bags and put into the mold of the extruder. Separation of slices; pressing adopts segmented boosting method, the pressure of the oil outlet section with a pressure of 15MPa is boosted at a speed of 2MPa / min, and the pressure is released after the pressure rises to 40MPa; the squeezed jatropha oil is filtered to remove residue or Centrifuge and remove slag to obtain crude oil a and oil residue, oil residue reclaims crude oil b by press filtration, mixes crude oil b with crude oil a, obtains Jatropha crude oil; heats the obtained Jatropha crude oil to 65...
