Abstract
There is described a process for producing hydrocarbon products in the diesel boiling range, comprising mainly C.sub.15 -C.sub.18 paraffins and being highly effective as diesel fuel ignition improvers. The process comprises hydroprocessing vegetable oils such as canola, sunflower, soybean and rapeseed oils or some fatty acids in hydroprocessing temperatures (350.degree.-450.degree. C.), pressures (4.8-15.2 MPa) and liquid hourly space velocity (LHSV) of 0.5-5.0 hr.sup.-1 depending on the type and purity of the feedstock. Commercially available hydroprocessing catalysts may be used.
