摘要：

The influence of oxide-oxide interaction on the catalytic properties of cobalt in CO hydrogenation is investigated on the example of a Co/Al2O3 catalyst. Oxide-oxide interaction was prevented by modification of the alumina surface with magnesia. It has been shown that oxide-oxide interaction affects catalytic activity and the amount of carbon deposited on the catalyst surface.
