The invention relates to a method for the selective absorption of nitrogen- and suplhur-bearing compounds contained in different fractions of petroleum hydrocarbons. The solid material used as an absorbent consists of a nano-structured material comprising a morphology of nanofibres and/or nanotubes of an inorganic oxide of a metal from group IVB with a high specific surface area of between 100 and 600 m2g. The inventive absorbent material may or may not be promoted with a transition metal and can selectively absorb nitrogen compounds exclusively or nitrogen and suplhur compounds simultaneously.
