- Abstract
This work deals with a composite catalyst preparation, Pt/HYH-Mordenite, for isomerization of Iraqi light naphtha produced from Baiji North Refinery in a pilot plant fixed bed reactor under operating conditions with the following ranges: temperature 150–250 °C, LHSV 2.46–4.7 hr-1, pressure 6 bar, and hydrogen to hydrocarbon ratio 3.7 mol/mol. The prepared nano-silica, Namordenite, H-mordenite, and Pt/HY-HMordenite catalysts were described by Xray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), and BrunauerEmmett-Teller (BET) surface area analysis. The investigation results showed that the light naphtha isomerization conversion and yield increased with increasing the temperature and decreasing the liquidhour space velocity. The highest conversion and yield, obtained at 250 °C and LHSV of 2.46 hr-1, were 89.38% and 76.36%, respectively.
