ABSTRACT:
Novel methods of treating a Fischer-Tropsch derived hydrocarbon stream with an active filtering catalyst are disclosed. Such methods are capable of removing soluble (and ultra-fine particulate) contamination, fouling agents, and/or plugging precursors from the Fischer-Tropsch derived hydrocarbon stream such that plugging of the catalyst beds of a subsequent hydroprocessing process is substantially avoided.
