Key of the process: Treatment with hydrogen. In the HVO production process, hydrogen is used to remove the oxygen from the triglycerides producing a mix of linear paraffins, CO 2 and water. Then, the product of the first stage is isomerized, always in presence of hydrogen, in order to branch the linear chains for improving the cold flow properties of the final products. Thus, HVO are mixtures of paraffinic hydrocarbons, free of sulphur and aromatics and with a very high cetane number. The hydrocarbons...
