METHOD FOR OBTAINING A FUEL FROM JATROPHA SEEDS THAT ARE RICH IN FAT.

摘要

The invention relates to a method for obtaining a fuel from plant seeds or nuts that are rich in fat, preferably jatropha seeds, with a fat content of at least 30 wt.%, preferably at least 40 wt.%, having the following steps: a) removing shell portions; b) comminuting the shelled seeds; c) adding water and/or acid to the comminuted plant seeds, thereby forming a suspension that contains oil; d) separating crude oil from the suspension, the pH value of the suspension being = 3.5 prior to separating the crude oil; e) polishing the oil or crude oil; f) neutralization; g) drying the oil; and optionally h) drying the de-oiled shred.
