Reduction of Emissions of Diesel-Biodiesel Fuel Blends Using Cerium Dioxide Catalyst Based on Carbon Nano Tubes

چکیده مقاله

The aim of this research was to study homogeneous nano-catalyst synthesis for reducing nitrogen oxides (NO_x), carbon monoxide (CO), unburned hydrocarbons (UHC) and soot resulted from diesel and two kinds of diesel-biodiesel compounds combustion in a diesel engine. The synthesized nano-catalyst was a hybrid of cerium nano-catalyst and functionalized multi-wall carbon nanotubes with amide function which was added to three types of fuel, namely diesel, 5% biodiesel +95% diesel (B5), and 20% biodiesel+ 80% diesel (B20) in a concentration of 30 ppm, 60 ppm and 90 ppm respectively. The results of this study showed that adding catalyst caused a significant decrease in the emissions (especially NO_x). Adding a nano-catalyst in a 90 ppm concentration to B20 caused the emission reduction for 18.90%, 38.8%, 71.4%, and 26.3% respectively in NOx, CO, UHC, and soot.
