Abstract:
A method of reducing the concentration of metal contaminants, such as vanadium and nickel, in distillates of a fossil fuel feedstock is disclosed. The method comprises producing a selected distillate fraction and demetallizing this distillate by suitable means, thereby upgrading and making it suitable for use as feed to a catalytic cracker.
