چکیده

در این مقاله مکانیسم هیدروژناسیون دی اکسید کربن به هیدروکربن های سنگین از طریق سنتز فیشر- تروپش توسط کاتالیست آهن، برای توسعه مدل سینتیکی مناسب مورد توجه قرار گرفته است. برای این منظور مدلهای سینتیکی فرآیند هیدروژناسیون دی اکسید کربن به روش لانگمویر- هینشل وود- هاگن – واتسون (LHHW) براساس واکنشهای بنیادی شامل مکانیسم های متداول در سنتز فیشر- تروپش و شیفت آب-گاز، توسعه یافتند. سپس پارامترهای موجود در این مدلهای سینتیکی با توجه به داده های تجربی و آنالیزهای آماری، مناسب سازی گردید. نتایج بدست آمده نشان می دهد که فرآیند هیدروژناسیون دی اکسید کربن بوسیله واکنش بین گونه های سطحی منوکسید کربن و هیدروژن محدود می شود. نتایج نشان می دهد که انرژی فعالسازی ظاهری برای مرحله رشد زنجیره هیدروکربنی بیشتر از مقادیر گزارش شده برای سنتز فیشر-تروپش (حدود 100 کیلوژول بر مول) است.این موضوع ممکن است به حضور گونه های حدواسط سطحی شرکت کننده در مکانیسم مربوط به واکنش شیفت آب-گاز مربوط باشد.

چکیده [English]

In this paper, the mechanism of hydrogenation of carbon dioxide to the heavy hydrocarbons through Fischer-Tropsch synthesis iron catalysts is considered for the development of suitable kinetic model. For this purpose, three kinetic models for carbon dioxide hydrogenation are developed using Langmuir-Hinshelwood-Hougen-Watson (LHHW) method based on basic reactions of Fischer-Tropsch Synthesis and water-gas shift reaction. The kinetic parameters in these models are obtained using empirical results. The results show that the reaction of hydrogenation of carbon dioxide is limited by reaction between surface species of adsorbed carbon monoxide and hydrogen. The results show that the activation energy for hydrocarbon growth in CO2 hydrogenation is higher than Fischer-Tropsch synthesis (100 kJ/mol).
