  • Description of Research:
    • The main objective on this research is to trace the residual solids and gases obtained from the thermal decomposition of urea, ammonium carbamate and guanidinium salts (acetate, carbonate and chloride). This solids have been researched as potential ammonia (NH3) producers. NH3 production is important for Selective Catalytic Reduction (SCR) applications, which are used frequently for nitrogen oxide (NOx) abatement. Ammonia production will be evaluated using Thermogravimetric Analysis coupled to Gas Chromatography coupled to Mass Spectrometry (TGA/GC-MS).

      Ammonia production from thermal decomposition of the above mentioned solids will be used for a SCR application in laboratory. A modified zeolite catalyst will also be used, in order to study the effects of the ammonia produced by thermal decomposition and the transition metals using diverse characterization thechniques as Fourier Transform Infrarred Spectroscopy (FT-IR), X-Ray Diffraction Spectroscopy (XRD), and microscopy image techniques as Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM).li>
