1. A process for the manufacture of diesel range hydrocarbons comprising:

  • combining a fresh feed stream of biological origin and a stream of diluting agent containing hydrocarbons to form a total feed stream,introducing the total feed stream to a hydrodeoxygenation step,hydrodeoxygenating the total feed, in the hydrodeoxygenating step,introducing the hydrodeoxygenated product to an isomerization step, andisomerizing the hydrodeoxygenated product in the isomerization step,whereinthe total feed stream contains less than 10 w-ppm alkali and alkaline earth metals, calculated as elemental alkali and alkaline earth metals, less than 10 w-ppm other metals, calculated as elemental metals, and less than 30 w-ppm phosphorous, calculated as elemental phosphorous.
