چکیده
مطالعه حاضر بر سنتز کربن فعال کم‌هزینه و کارآمد از پوست گردوهای ضایعاتی و کاربرد آن در غشاهای ماتریس مخلوط پلی ‌اتر سولفون (PES) برای جداسازی انتخابی CO₂/CH₄ متمرکز بود. پس از کربونیزه کردن، پوست گردوها به‌صورت شیمیایی با ZnCl₂ و KOH فعال شدند. ویژگی‌های ساختاری و شیمیایی کربن فعال با استفاده از طیف‌سنجی فروسرخ تبدیل فوریه (FTIR) و میکروسکوپ الکترونی روبشی (SEM) بررسی شد که توزیع موفقیت‌آمیز ذرات کربن در سراسر ماتریس پلیمری را تأیید کرد. همچنین، سطح ویژه و ساختار منافذ کربن فعال تولیدشده با استفاده از روش بروناور–امت–تلر (BET) شناسایی شد. علاوه بر این، مقادیر مختلفی از کربن فعال با استفاده از روش حلال‌آمیختگی (solution-mixing) در PES گنجانده شد و سپس از طریق تکنیک وارون‌سازی فاز (Phase inversion) روی یک زیرلایه پلی‌استری ریخته شد. عملکرد جداسازی غشاهای ساخته‌شده از طریق آزمایش‌های نفوذپذیری گاز خالص ارزیابی شد. نتایج نشان داد که غشاهای ماتریس مخلوط (MMMs) نسبت به غشاهای PES خالص، بهبود قابل‌توجهی در عملکرد جداسازی CO₂/CH₄ از خود نشان دادند. همچنین، مقایسه با حد بالای رابسون نشان داد که غشاهای ماتریس آمیخته به حد تبادل نفوذپذیری–انتخاب‌پذیری گزارش‌شده نزدیک شده‌اند. اگرچه برای فراتر رفتن از این حد و به‌طور کامل بهینه‌سازی عملکرد غشا، به تحقیقات بیشتری نیاز است، نتایج به‌وضوح مؤثر بودن پرکننده‌های استخراج‌شده از ضایعات کشاورزی در طراحی پیشرفته غشاها را برجسته می‌کند. به‌طور کلی، این مطالعه پتانسیل تبدیل پوست گردو به کربن فعال باارزش را برای توسعه غشاهای ماتریس آمیخته‌ی مقرون‌به‌صرفه، دوستدار محیط‌زیست و با عملکرد بالا در جداسازی گاز طبیعی نشان می‌دهد.

چکیده English

The present research focused on synthesizing low-cost, efficient activated carbon from waste walnut shells and applying it in polyethersulfone (PES) mixed matrix membranes for selective CO₂/CH₄ separation. After carbonization, walnut shells were chemically activated with ZnCl₂ and KOH. spectroscopy. The structural and chemical characteristics of the activated carbon were investigated by Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM), which confirmed the successful distribution of carbon particles throughout the polymer matrix. Also, the surface area and pore structure of the produced activated carbon were characterized using Brunauer–Emmett–Teller (BET). Moreover, varying amounts of activated carbon were incorporated into PES using the solution-mixing method and subsequently cast onto a polyester support via the phase inversion technique. The separation performance of the fabricated membranes was evaluated through pure gas permeability experiments. The results demonstrated that the MMMs exhibited a significant enhancement in CO₂/CH₄ separation performance compared to pristine PES membranes. Furthermore, comparison with the Robeson upper bound revealed that the MMMs approached the reported permeability–selectivity trade-off limit. Although further optimization is necessary to surpass this limit and fully maximize membrane efficiency, the outcomes clearly underscore the effectiveness of agricultural waste-derived fillers in advanced membrane design. Overall, this research demonstrates the potential of converting walnut shells into valuable activated carbon for the development of cost-effective, environmentally friendly, and high-performance mixed-matrix membranes for natural gas separation.
