Abstract

The hydrogenation of CO2 has been studied at atmospheric pressure on Co/C and Ni/C catalysts and the results are compared with those obtained on unsupported Co and Ni. Specific activites in the form of turnover frequencies for CO2 hydrogenation decrease with increasing metal dispersity. Carbon supported Co and Ni present a smaller selectivity for methane than bulk metals. Higher specific activities and smaller activation energies are obtained on Co catalysts, compared with those determined for Ni catalysts.

Abstract

Гидрирование CO2 изучено при атмосферном давлении на катализаторах Co/уголь и Ni/уголь и лолученные результаты сравниваются с результатами на катализаторах Co и Ni без носителей. Специфическая активность в форме частоты превращения для гидрирования CO2 уменьшается с увеличением дисперсности металла. Co и Ni на углероде имеют меньшую селективность, чем блочные металлы. Кобальтовые катализаторы обладают более высокой специфической активностью и меньшей энергией активации по сравнению с никелевыми катализаторами.
