✦ Synopsis

powered refrigeration (12)(13)(14)(15)(16), owing to the Type I adsorp-Adsorption isotherms of water vapor on active carbon preadtion isotherm and the large latent heat of vaporization of sorbed with small amounts of methanol and benzene are measured methanol (872 kJ/dm 3 ( 14)). On the other hand water canand the influence of the preadsorbates on the following water not be used as adsorbate (refrigerant) in spite of the largest vapor adsorption is discussed in terms of the number of primary latent heat of vaporization (2163 kJ/dm 3 ( 14)) due to the adsorption centers a 0 for water vapor adsorption by the Dubinin-Type V adsorption isotherm. But certain kinds of active

The results show that methanol is terephthalamide) (17) show water vapor adsorption isoadsorbed on the edges of the micropore walls, where oxygensurface complexes exist and the adsorption space for water in therms with the upswing adsorption at the low relative presmicropores is maintained, while benzene is adsorbed on the basal sure. The isotherms are upswung almost linearly in the range planes, which diminishes the adsorption space for water vapor in of 0 £ the relative pressure P/P 0 £ ca. 0.4 and afterward micropores. ᭧ 1997 Academic Press lead to a plateau or an upturn as saturation is approached.
