The adsorption equilibrium of water on microporous adsorbents (zeolites of NaA-, NaY- and NaX-type as well as their ion exchanged forms) and on mesoporous adsorbents (different silica gels and composite material i.e. silica gel + salt hydrate) has be

For the determination of the heat of a given process with a differential scanning calorimeter, it is not only necessary to measure the DSC curve, but also to construct the baseline. If the differential scanning calorimeter is coupled with a balance,

The influence of the framework density, the chemical composition, and derived from those the influence of the effective electronegativities of silica and aluminophosphate molecular sieves on the adsorption properties have been investigated experiment

Calorimetric measurements of the chemisorption heats of ammonia were used to investigate the acid strength of dealuminated Y-zeolites. Our measurements show that the number of very strong acid sites rises, passes through a pronounced maximum and then

Calometric measurements of the heat of adsorption of nonpolar molecules on VPI-5 were performed at 303 K and compared with the results of measurements of the same molecules on the silica faujasite (US-Ex). Both microporous adsorbents show similar ads

The adsorption of water, methanol and acetonitrile in ZK-5 was investigated using temperature programmed desorption, microcalorimetry and FTIR spectroscopy. A multi-stage desorption in the TPD, steps in the isotherms and a stepwise decrease of the he
