The process comprises hydroprocessing vegetable oils such as canola, sunflower, soybean and rapeseed oils or some fatty acids in hydroprocessing temperatures (350°-450° C.), pressures (4.8-15.2 MPa) and liquid hourly space velocity (LHSV) of 0.5-5.0 hr-1 depending on the type and purity of the feedstock. Commercially available hydroprocessing catalysts may be used. |
