Abstract
A method for preparing hydrocarbons includes subjecting a renewable feedstock comprising lipophilic phosphorus compounds to a hydrotreatment process to form hydrocarbons from the renewable feedstock. In some embodiments, the content of the lipophilic phosphorus compounds in the renewable feedstock can be in a range of between 2 parts per million by weight (wppm) and 0.1 wppm so that deactivation of a catalyst used in the hydrotreatment process is reduced or avoided. In some embodiments, a feedstock can be determined to include an amount of 'difficult to remove' phosphorus and the result thereof can be used for selecting a suitable pretreatment to which the feedstock can then be subjected. The pretreated renewable feedstock can then be hydrotreated catalytically.
