چکیده

فرآیند رفرمینگ متان با بخار بالاترین بازدهی را نسبت به سایر روش‌های تولید هیدروژن دارد. نقش دما، فشار، نسبت بخار به کربن ورودی و کاتالیست دارای اهمیت است. در تحقیق حاضر، یک حل عددی با استفاده از نرم‌افزار منبع باز کانترا در محیط برنامه‌نویسی پایتون، برای تولید گاز سنتز و هیدروژن به روش رفرمینگ متان با بخار در حضور دو کاتالیست نیکل و رادیوم ارائه می‌گردد. مدل‌سازی در محدوده گسترده دمایی 600-1300 کلوین، نسبت بخار به کربن ۲-۴ و فشار 5/25-۴ بار به‌منظور تعیین کاتالیست مناسب و بهترین محدوده برای تولید هیدروژن، گاز سنتز و کاهش پوشش سطحی کربن انجام می‌شود. نتایج نشان می‌دهد که محدوده مناسب برای تولید هیدروژن در حضور کاتالیست نیکل و رادیوم بازه 10۰۰ تا ۱1۰۰ کلوین، فشار ۱-2 بار و نسبت بخار به کربن به ترتیب 2/5-3 و ۳-3/5 است. برای تولید گاز سنتز در حضور کاتالیست نیکل و رادیوم به ترتیب بازه ۱۲۰۰- ۱۳۰۰ و ۱1۰۰-۱۳۰۰ کلوین، نسبت بخار به کربن 2/5-3 و ۳-3/5 و فشار ۱-2 بار پیشنهاد می‌گردد. همچنین، کاتالیست رادیوم از نیکل در شرایط یکسان فعال‌تر می‌باشد؛ اما ازآنجاکه رسوب پوشش سطحی کربن روی بستر کاتالیست نیکل کمتر است، کاتالیست نیکل برای انجام فرآیند رفرمینگ متان با بخار پیشنهاد می‌شود.

چکیده [English]

Steam methane reforming has the highest efficiency compared with other hydrogen production ways. Temperature, pressure, steam to methane ratio, and catalyst play essential roles in the Steam methane reforming process. In this paper, a numerical simulation method is performed using Cantera software in Python programming language to produce syngas and hydrogen in the Steam methane reforming process over Nickel- and Rhodium-based catalysts. The simulation is done in 600-1300K, steam to methane ratio of 2-4, and pressure of 0.25-4 bars to determine a suitable catalyst and the best range to produce hydrogen and syngas and to reduce Carbone surface coverage. The results demonstrate that the preferred ranges for hydrogen production over Nickel and Rhodium are temperature between 1000 to 1100K, pressure 1 to 2 bars, and steam to methane ratio 2.5 to 3 and 3 to 3.5 for each, respectively. The appropriate ranges to produce syngas over Nickel and Rhodium are temperature 1200-1300K and 1100-1300K, steam to methane ratio 2.5-3 and 3-3.5, respectively, and the pressure is suggested between 1-2 bars. However, Rhodium in the same condition is more active than Nickel, while the surface coverage formation is lower over Nickel than Rhodium. Therefore, Nickel is proposed to produce hydrogen via Steam Methane Reforming.
