Abstract
Process for catalytic reduction of nitrogen oxides (NOx) in the presence of hydrogen (H2) by contacting a gaseous feed comprising nitrogen oxides and a catalyst, at a temperature between 15°C and 600°C, at a VVH between 10,000 h-1 and 150,000 h-1, the molar ratio H2 / NOx being between 2:1 and 100:1, said catalyst comprising palladium, at a content between 0.01 and 8% by weight of element palladium relative to the total weight of the catalyst, and a support comprising titanium dioxide, said catalyst being obtained by a preparation process comprising a step of impregnation of palladium by colloidal means.
