dc.descriptionDiesel engine technology has been driven by increasingly stringent environmental legislation. To comply with these laws, emissions-control systems are being rapidly improved. Within this context, development of exhaust gas after-treatment systems undertakes a significant role. Among the techniques used is selective catalytic reduction (SCR), which converts nitrogen oxides (NOx) into diatomic nitrogen (N-2) and water (H2O). A reducing agent containing ammonia (NH3) is added to the flow and absorbed by a catalyst. Different reducing agents are currently used, principally anhydrous NH3, aqueous NH3, and urea. This study analyzed behavior of different urea-and formamide-based agents to SCR. Results are compared to those obtained with Adblue. In relation to the SCR system as well as to NOx reduction, we concluded that urea-based mixtures are the most efficient, although they present higher values of NH3 slip. Formamide-based mixtures are significantly less efficient than urea-based mixtures, but the NH3 slip levels produced by these mixtures are virtually none. A challenge is to find new reducing agent for SCR applications, considering that the deposits of urea formed during certain work conditions are a significant problem.
