This study was an attempt to produce syn-gas (H2, CO), which is used as a reducing agent in SCR (Selective catalytic reduction) of NOx, by partial oxidation of hexadecane over Rh catalysts. Employed catalysts were 0.2 wt% Rh-supported on Al2O3 and Ce-Zr-LaOX and these were characterized using XRD, BET, NH3/hexadecane-TPD, H2-TPR, and XPS. The reaction temperature ranged from 200℃ to 800℃, and space velocity and C/O ratio were fixed 25000h-1 and 0.5, respectively. The hexadecane conversion and H2 selectivity increased with increase of reaction temperature in all catalysts. The best conversion of hexadecane reached near 100% at 700℃ and the selectivity of CO and H2 increased up to 800℃, continually. |
