After ripening, the jatropha fruit is first screened by breaking the shell, and then the oil is refined by pressing or leaching, and then the crude methyl ester and glycerol are obtained through transesterification, and then distilled to obtain qualified biodiesel.
I'm going to describe this process very simply, but the investment is relatively large, and it is divided into four major parts.
1. From picking to fruit screening and shell breaking treatment After breaking the shell, it should be crushed and dried.
2. The dried fruit is extracted from the fruit by leaching or pressing The knowledge of grain and oil processing is included, and you can find books in the bookstore.
3. The principle of transesterification is used to transesterify the extracted oils, and then glycerol and methanol are separated.
4. Purify and distill the crude methyl ester so that the qualified biodiesel is made, I simply say that these are all included in the huge investment and caution!
This is the process of making biodiesel from jatropha nuts, which includes chemical reactions, and if you want to be more detailed, no one will tell you, because there are too many of them, and he can solve them not only in chemistry, but also in oil processing.

Biodiesel is an automatic vegetable oil that is commonly used in tractors, trucks, ships, etc. It refers to the renewable diesel fuel made from oil crops such as soybean, rapeseed, cotton, palm, etc., aquatic vegetable oils and fats such as wild oil plants and engineered microalgae, as well as animal fats and catering waste oils, etc., which can replace petrochemical diesel through transesterification or thermochemical processes. Biodiesel is a type of biomass energy, which is close to petrochemical diesel in physical properties, but different in chemical composition.
Biodiesel is a mixture of complex organic components with extremely high oxygen content, which are mainly organic compounds with large molecular weight, including almost all kinds of oxygenated organic compounds, such as: esters, ethers, aldehydes, ketones, phenols, organic acids, alcohols, etc. Compound biodiesel is synthesized from waste animal and vegetable oil, waste engine oil and by-products of oil refineries as raw materials, and then added with catalysts and special equipment.

Ginkgo biloba, also known as ginkgo, ginkgo biloba is the oldest plant on the earth, ginkgo biloba is also known as a living fossil of plants, ginkgo biloba is a tall deciduous tree, its life span can reach more than three thousand years, ginkgo biloba tree was first in China, and now almost all over the world are planted. The whole body of the ginkgo tree is full of medicinal herbs, and the ginkgo biloba tea can lower blood pressure and blood lipids. It is best to use ginkgo biloba leaves after frost. >>>More
