摘要：

Acidity of Ni-modified alumina and silica-alumina catalysts was determined using n-butylamine titration and pyridine adsorption methods. Strong influence of Ni2+ ions on the Bronsted acidity of silica-alumina was observed. Improved Bronsted acidity of such system was confirmed by the results of the test reaction.
