Abstract

The European Union (UE) renewable energy requirements for next years, are working as engine to develop new, more efficient and environmentally friendly bio-fuels. The hydro-treated vegetable oil (HVO) or Green diesel is a paraffinic diesel fuel produced via catalytic hydro-treatment of vegetable oils at high temperature and pressure [1].The co-processing of triglycerides feedstocks such used cooking oils (UCO), in an industrial hydrodesulphurization unit could be very attractive for refineries. It is because not only can be employed the existing installations [2], but it is obtained a bio-fuel that is integrated with the desulphurized gasoil, improving some of their properties such as density at 15 ᵒC and flammability.At the industrial conditions (350-370 ᵒC and 70-80bar), the triglycerides are hydrogenated according with the pathways of Figure 1.
