Selective catalytic reduction (SCR) catalyst comprising V and Sb-containing complex oxides, a process for its preparation and its use for the removal of nitrogen oxides

摘要

A support comprising TiO ₂ for selective catalytic reduction of nitrogen oxides, a rutile-type structure different from VSbO ₄ and V _0.92 Sb _0.92 O ₄ as determined by X-ray diffraction (XRD) analysis using Cu Kα radiation A catalyst composition comprising at least one selected from the group consisting of silicon oxides, vanadium oxides and antimony oxides, a process for preparing a catalyst composition, a process for producing a catalyst composition obtainable / obtainable by the process Catalyst compositions, and uses thereof for selective catalytic reduction of nitrogen oxides are provided.
