Abstract

It is shown that, in contrast to classical impregnation methods, in bimetallic catalyst production the texture of the carrier is stabilized by introducing the promoting ion on the surface of Pt/Al2O3 with vapors of CrO2Cl2 or SnCl4. This is shown by a relatively slower decrease of the specific area and the volume of the pores upon calcination.

Abstract

Показано, что в различие от классических методов импрегнирования при получении биметаллических катализаторов в результате введения промотирующего йона на поверхность Pt/Al2O3-катализатора с порами CrO2Cl2 или SnCl4 стабилизируется текстура носителя. Это выражается в относительно медленном уменьшении удельной поверхности и обьем пор при обжиге.
