Abstract

The present study reports a new and original technique for obtaining nickel catalysts characterized by small metal crystallites. The catalysts were prepared on γ-Al2O3. The total surface of the carrier was 37.5 m2/g. The preservation of the appropriate procedure and conditions of preparation allow a large expansion of active nickel surface (mean crystallite size 2.0–3.0 nm) in spite of the quite hard conditions of reduction (773 K and 3 h).

Abstract

В данном сообщении приводится новая и оригинальная техника получения никелевых катализаторов, характеризуемых малыми металлическими кристаллитами. Катализаторы были приготовлены на γ-Al2O3. Общая поверхность носителя равнялась 37,5 м2/г. Соблюдение подходящей процедуры и условий приготовления приводит к большому повышению активной поверхности (средние размеры кристаллита 2,0–3,0 нм) несмотря на относительно жесткие условия восстановления (3 часа при 773 К).
