Abstract
This work deals with a composite catalyst preparation, Pt/HY-H-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, Na-mordenite, H-mordenite, and Pt/HY-H-Mordenite catalysts were described by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer-Emmett-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 liquid-hour 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.
本文研究了Pt/ hy - h -丝光沸石复合催化剂的制备，用于在固定床反应器中试装置中，在温度150 ~ 250℃，LHSV 2.46 ~ 4.7 hr-1，压力6 bar，氢烃比3.7 mol/mol的条件下，对Baiji北炼油厂生产的伊拉克轻油进行异构化反应。采用x射线衍射(XRD)、场发射扫描电镜(FE-SEM)、傅里叶变换红外光谱(FTIR)和布鲁诺尔-埃米特-泰勒(BET)表面积分析对制备的纳米二氧化硅、na -丝光石、h -丝光石和Pt/ hy - h -丝光石催化剂进行了表征。研究结果表明，轻质油异构化转化率和产率随温度的升高和液时空速的降低而提高。在250°C和LHSV为2.46 hr-1时，转化率和产率分别为89.38%和76.36%。
