چکیده
در این مطالعه، تأثیر حضور کاتالیستγ_Al2O3  در محلول پایۀ 3 مولار متیل‌دی‌اتانول آمین برای دفع کربن‌دی‌اکسید و احیای محلول بررسی‌شد. باتوجه‌به نتایج این پژوهش، این کاتالیست موجب افزایش 6/3 تا 17/9 درصدی میزان دفع کربن‌دی‌اکسید شده‌است. در این پژوهش، به بررسی تأثیر افزودن مونو اتانول آمین با غلظت 1 مولار و هم‌چنین پیپرازین با غلظت 0/5 مولار به محلول پایه پرداخته‌شده‌است. نتایج حاصل‌از این پژوهش نشان‌داد که با افزودن آمین‌های مختلف با غلطت‌های مشخص به محلول پایه، میزان دفع کربن‌دی‌اکسید افزایش‌یافت. میزان دفع کربن‌دی‌اکسید تا 26/1درصد در این مرحله بیشتر شد. در تمامی آزمایش‌ها، بیشترین میزان دفع کربن‌دی‌اکسید مربوط‌به مخلوط سه‌آمینی و استفاده‌از 45 گرم کاتالیست g_  بود که میزان دفع تا 39/3 درصد افزایش‌یافت.

چکیده English

In this study, the effect of the presence of g_  catalyst in 3 M methyl diethanolamine solution for removing carbon dioxide and regenerating the solution has been investigated. According to the results obtained from this research, this catalyst has caused an increase of 6.3 to 17.9 percent in the amount of carbon dioxide removal. Also, in this research, the effect of adding monoethanolamine with a concentration of 1 M and also piperazine with a concentration of 0.5 M to a base solution of 3 M methyldiethanolamine has been investigated. The results of this research showed that by adding different amines with specific concentrations to the methyldiethanolamine solution, it is possible to increase the amount of carbon dioxide removal. The amount of carbon dioxide removal increased to 26.1% in this stage. In all the experiments, the highest amount of carbon dioxide removal was related to the three-amine mixture and applying 45 grams of g_  catalyst, which increased the amount of removal to 39.3%.
