Abstract
Two simple and rapid gas chromatographic techniques based on adsorption and thermal desorption of pyridine, viz., stepwise thermal desorption and temperature-programmed desorption under chromatographic conditions, for measuring the acid strength distribution on solid catalysts at temperatures close to those employed in catalytic reactions are described. These methods have been employed to carry out such measurements on CeY zeolite in the temperature range 353-623°K. The results obtained from the two techniques indicate that the CeY has a broad acid strength distribution.
