Abstract

The hydrogenation of CO2 on activated carbon-supported iron catalysts has been carried out at atmospheric pressure and using a H2/CO2 ratio of 4. The specific activities for this reaction are lower than those obtained for the Fischer-Tropsch synthesis using the same catalysts. CO and CH4 are the only products obtained in the hydrogenation of CO2 under the experimental conditions used. The apparent activation energies determined for the production of CO are lower than those for the production of CH4.

Abstract

Гидрирование CO2 на железных катализаторах, нанесенных на активированный углерод, исследовано при атмосферном давлении и при соотношении H2/CO2=4. Специфическая активность для этой реакции ниже, чем в синтезе Фишера-Тропша на тех же самых катализаторах. CO и CH4 являются единственными продуктами, образующимися в гидрировании CO2 в данных экспериментальных условиях. Кажущаяся энергия активации обра-зования CO ниже, чем энергия активации образования CH4.
