چکیده
به‌عنوان یکی از روی‌کردهای امیدبخش، هیدروژناسیون ترموکاتالیستی کربن‌دی‌اکسید به متانول از راه کاتالیز ناهمگن توجه زیادی را در دهه‌های گذشته به خود جلب کرده‌است. در صنعت، متانول از واکنش گاز سنتز (مخلوط گازهای هیدروژن و کربن مونواکسید) و کربن‌دی‌اکسید با‌استفاده‌از کاتالیست‌های Cu/ZnO/Al2O3 تولید می‌شود. هم‌رسوبی نیترات‌های Cu/Zn/Al به‌وسیلۀ سدیم کربنات، روشی غالب و استاندارد است که برای سنتز صنعتی کاتالیست متانول به‌کار می‌رود. این کاتالیست سه‌تایی به تغییرات جزئی اجزای فلزی و مشخصه‌های سنتز بسیار حساس است. کاری که در این‌جا ارائه شده، بررسی اثر دماهای تکلیس (300، 350 و 400 درجۀ سلسیوس) و زمان‌های رشد بلور (2 ، 7 و 18 ساعت) بر ساختار و خواص کاتالیست‌های Cu/ZnO/Al2O3 است و این نتیجه حاصل شد که دمای تکلیس 350 درجۀ سلسیوس و زمان رشد بلور 7 ساعت، به‌ترتیب دمای تکلیس و زمان رشد بلور بهینه برای سنتز این کاتالیست است.

چکیده English

As one of the promising approaches, the thermocatalytic hydrogenation of carbon dioxide to methanol through a heterogeneous catalyst has attracted much attention in the past decades. In industry, methanol is produced from the reaction of syngas (H2+CO) and carbon dioxide over CuO/ZnO/Al2O3 (CZA) catalysts. Co-precipitation of Cu/Zn/Al nitrates by sodium carbonate is the dominant and standard technique used for the industrial synthesis of methanol catalysts. This three-component catalyst is very sensitive to slight changes in metal components and synthesis parameters. In this study, the effect of calcination temperatures (300, 350, and 400°C) and aging time (2, 7, and 18 hours) on the structure and textural properties of CuO/ZnO/Al2O3 catalysts have been investigated using the BET, XRD, H2-TPR, and FE-SEM analyses.
The results show that the most appropriate catalyst could be synthesized when the calcination temperature and the aging period were set to 350°C and 7 hours, respectively.
