1. A method for preparing hydrocarbons, the method comprising:
evaluating a renewable feedstock before the renewable feedstock is subjected to a hydrotreatment process to determine a content of lipophilic phosphorus compounds in the renewable feedstock; and
in response to a determination that the content of the lipophilic phosphorus compounds in the renewable feedstock is greater than a pre-selected lipophilic phosphorus content threshold, pretreating the renewable feedstock via at least one pretreatment process to lower the content of the lipophilic phosphorus compounds within the renewable feedstock so the content of the lipophilic phosphorus compounds in the renewable feedstock is less than 2 parts per million by weight (wppm) and greater than or equal to 0.1 wppm;
subjecting the renewable feedstock to the hydrotreatment process to form hydrocarbons from the renewable feedstock;
wherein a content of the lipophilic phosphorus compounds in the renewable feedstock subjected to the hydrotreatment process is in a range of between less than 2 wppm and 0.1 wppm so that deactivation of a catalyst used in the hydrotreatment process is reduced or avoided.
