Abstract:
1. A process for the manufacture of diesel range hydrocarbons, wherein total feed comprising fresh feed is hydrotreated in a hydrotreating step to form a hydrotreated product, and the hydrotreated product is isomerised in an isomerisation step to form diesel range hydrocarbons, and wherein the fresh feed comprises at least 20% by weight of triglyceride C 12 -C 16 fatty acids, C 12 -C 16 fatty acid esters, C 12 -C 16 fatty acids, or combinations thereof, wherein at least one inorganic or organic sulphur compound or a refinery gas and/or liquid stream containing sulphur compounds is added to the total feed or fresh feed to give a total feed comprising 100-10,000 w-ppm sulphur calculated as elemental sulphur, wherein during the hydrotreating step, the pressure is in the range of 2-15 MPa, and the temperature is between 200 and 400° C., and wherein during the isomerisation step, the pressure is in the range of 2-15 MPa, and the temperature is between 200 and 500° C.
