Abstract |
The selective catalytic reduction (SCR) system is exhaust emission control system used for reductions of nitrogen oxide (NOx) emissions in diesel engines with the help of catalyst and reductant. Hydrocarbon-selective catalytic reduction (HC-SCR) is a system in which hydrocarbons such as ethanol, propanol and pentanol are used as reductant. In this empirical study, synthesizing of catalyst for HC-SCR systems was carried out with impregnation method. In order to prepare solution, a mixture including silver nitrate (AgNO3), titanium dioxide (TiO2) and oxalic acid (C2H2O4x2H2O) and tetra ammine palladium (II) nitrate solution (Pd(NO3)2.4NH3) were used to coat the cordierite (2Al2O3-5SiO2-2MgO) structure. Thus, the production of catalyst containing Ag, Pd and Ti was realized. Various analyzes were carried outto determine morphology of catalyst with Scanning Electron Microscopy (SEM), to determine the surface area of the catalyst with Brunauer, Emmett and Teller (BET) method, and in order to detect Ag-Pd-Ti coating materials in the catalyst with Inductively Coupled Mass Plasma Spectrometer (ICP-MS). Oxalic acid treatment has a significant effect on the expansion of the surface area of the cordierite.The coating materials is seen to cling on the main structure surface and pores. Moreover, distribution of these materials on the main structure surface and pores is homogeneous. Keywords - Cordierite, Hc-Scr, Impregnation Method, Acid Treatment. | |||||||||
