Abstract: A method for removing alkali metal from a hydrocarbon feedstock comprising alkali metal, non-alkali metal and sulfur. The method includes separating out at least a portion of any alkali metal sulfide and a portion of any non-alkali metal from the hydrocarbon feedstock. Hydrogen sulfide can be added to the remaining hydrocarbon feedstock to form alkali hydrosulfide from any alkali metal remaining in the hydrocarbon feedstock. The alkali hydrosulfide is then separated from the hydrocarbon feedstock. Alkali metal may be removed from the alkali metal sulfide separated out from the hydrocarbon feedstock. Alkali hydrosulfide may be treated to form alkali metal sulfide, and alkali metal may also be removed from the formed alkali metal sulfide.
