Hydrotreated vegetable oil
Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking and hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation eliminates double bonds by adding hydrogen to the molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock. Diesel fuel produced from these sources is sometimes referred to as green diesel or renewable diesel.
Diesel fuel created by hydrotreating is distinct from the biodiesel made through esterification.
