- Abstract
- La-modified Fe/MgAlO catalysts were prepared by methods of joint and sequential impregnation of the carrier – alumina-magnesium spinel. The data of TPV (temperature-programmed reduction) and in situ magnetometry showed that the catalyst obtained by lanthanum promotion of spinel is reduced more efficiently in comparison with the catalysts synthesized by other methods of lanthanum introduction into their composition. The data on adsorption and reduction properties of the catalysts by in situ magnetic method, low-temperature nitrogen adsorption and IR spectroscopy of adsorbed CO have been compared. It was found that the presence of lanthanum in the catalyst accelerates the reduction of iron oxides to iron.
