Among the routes considered for the synthesis of renewable HCs (pyrolysis, oligomerization, fermentation, and deoxygenation DOX), Vásquez et al. describe that the DOX of oils and animal fats via hydroprocessing technology is at a higher degree of technological maturity in terms of scale of production and, consequently, development.

Oils and fats (vegetal or animal) are important components of the foods. There are a wide variety of products based entirely on fats and oils or containing fats and oils as a major portion of their composition, such as cocoa butter, salad and cooking oils, margarines, shortenings, salad dressings, and confectioner's coatings (O'Brien, 2009).
