ABSTRACT:
The process of the present invention involves reducing the sulfur and/or nitrogen content of a distillate feedstock to produce a refinery transportation fuel or blending components for refinery transportation fuel, by contacting the feedstock with an oxygen-containing gas in an oxidation zone at oxidation conditions in the presence of an oxidation catalyst comprising a zeolitic material, TIQ-6, whose chemical composition corresponds to the formula, expressed as oxides,in-line-formulae description="In-line Formulae" end="lead"?SiO2:zZO2:mMO2:xX2O3:aH2Oin-line-formulae description="In-line Formulae" end="tail"?WhereinZ is Ge, Sn,z is between 0 and 0.25 mol.mol−1M is Ti or Zr,M has a value between 0.00001 and 0.25, preferably between 0.001 and 0.01, anda=has a value between 0 and 2.
