Abstract

Infrared spectra in the structural region and X-ray investigations indicate that during the Claus reaction on X-type zeolites partial dealumination of the crystal structure occurs. The dealumination is smaller at 453 K than at 343 K. This type of dealumination has not been observed on Y-type zeolites.

Abstract

ИК спектры в структуральной области и рентгеноспектроскопия указывают на то, что в ходе реакции Клауса на цеолитах типа Х происходит частичное деалюминирование кристаллической структуры. Деалюминирование слабее при 453 К, чем при 343 К. Такого рода деалюминирование не наблюдалось на цеолитах типа У.
