Abstract: 
The Selective Catalytic Reduction (SCR) of NOx has been performed in a real diesel exhaust stream with commercial diesel fuel by using a full size home-made Pt/beta zeolite/honeycomb prototype catalyst. Fuel was injected upstream the catalyst to achieve total hydrocarbons concentrations between 1000 and 5000 ppm, and the SCR behaviour observed was similar to that typically reported in laboratory experiments performed with model hydrocarbons. Typical NOx removal volcano-shape profiles, with maxima at 250 °C for all THC inlet concentrations, were obtained, with an optimum THC concentration of 3000 ppm.
