摘要：

A temperature-programmed desorption of adsorbed dimethylpyridine clarified the characteristic changes in acid type, acid strength, and acid amount of silicaalumina prepared by depositing silica on an alumina support. Lewis acid sites of the alumina changed into Bronsted acid sites together with a change in the acid strength with increasing silica deposition.
