| چکیده | ||
| طرح تولید H2 خالص برای مصارف پیل سوختی پلیمری با ریفرمینگ حلقه شیمیایی متانول و حامل اکسیژنی 0.3CoFe2O4-0.4ZrO2 در راکتور میکروکانال مورد مطالعه قرار گرفت و نتایج این تحقیق نشان داد تولید H2 خالص تنها در صورت کنترل رسوب کک امکانپذیر است. با بهینه سازی زمان واکنش احیا به 7 دقیقه، رسوب کک، کنترل و جریان H2 خالص با بازدهی متوسط 6/2% تولید شد که نتیجه ای جالب بود و تاکنون این درجه خلوص با روش حلقه شیمیایی متانول گزارش نشده است. برای افزایش بازدهی در این طرح، دو لایه کاتالیست بصورت پوشش یک لایه اضافه با خاصیت مقاومت بالا به کک و واکنش پذیری مناسب با متانول با ترکیب 10% از NiO/MgAl2O4 بر روی 0.3CoFe2O4-0.4ZrO2 پیشنهاد شد. بهینه سازی زمان واکنش با استفاده از حامل اکسیژنی دولایه ای نشان داد استفاده از غلظت 20% نیکل در زمان واکنش 11 دقیقه، سبب افزایش بازدهی H2 با خلوص 100% شد که به مقدار 42% در آرایش دولایه ای نسبت به حالت تک لایه افزایش داشته و یک نتیجه امیدبخش برای حامل اکسیژنی دولایه ای در این فرآیند می باشد. | ||

| چکیده [English] | ||
| The production of pure H2 for polymer fuel cells was studied by the chemical loop reforming of methanol in the presence of 0.3CoFe2O4-0.4ZrO2 as an oxygen carrier in a micro-channel reactor. The results of this study showed that the production of pure H2 is possible only if the coke deposition is controlled. By optimizing the reduction time to 7 minutes, the coke deposition controlled and pure H2 flow was produced with an average yield of 2.6%, which was an interesting result and so far this degree of purity of H2 has not been reported by the chemical loop reforming of methanol. To increase the yield of pure H2 in this study, a two-layer catalyst concept is proposed in the form of an additional layer coating with high resistance to coke and suitable reactivity with methanol from NiO/MgAl2O4 to 10% on 0.3CoFe2O4-0.4ZrO2 layer. Optimization of various parameters using the concept of double-layer oxygen carrier showed that the use of 20% nickel concentration with a reduction time of 11 minutes increased the yield of H2 with 100% purity, which increased by 42% in the double-layer arrangement compared to the single-layer state, and it is a promising result for the concept of bi-layer oxygen carrier in this process. | ||
