The H+ mordenite sample was prepared by hydrochloric acid exchange.It was calcined under vaouum at 400℃ for 24 hr,cooled to room temperature and then allowed to adsorb pyridine vapour for 30 min.The absorption bands of pyridine adsorbed on H+ mordenite surfaoe were observed at relatively low temperature,after oalcination in vacuum the temperatures of ealcination being 250°,300°,350°,and 400℃.
