Abstract
Ammonia was used for adsorption on calcined dealuminated NH-clinoptilo lite. Four acid site types of clinoptilolite were determined by TPD. E xtraframework aluminium remained in clinoptilolite structure after dea lumination increases the relative number of weak acid sites and has bl ocking influence on strong acid sites determination.
