A method for the sorption of organic compounds using a sorbent, comprising activated carbon in a preferably amorphous oxidic support is described. Novel sorbents are also described.

Sorption of organic compounds from fluids

In a process for adsorption cooling/conditioning of rooms, working media are used which comprise saturated aqueous solutions of calcium salts with an added organic polyhydroxy compound. The working media are distinguished by high salt contents and low salt precipitation temperatures at very low water vapor partial pressures and are suitable for use in continuously operated adsorption/desorption cycles of adsorption cooling/conditioning systems having high coefficients of performance.

Process for adsorption cooling/conditioning by means of low-temperature

A process for catalytically reducing nitrogen oxides in an exhaust gas such as a combustion gas and a catalyst suitable for use therein. The catalyst comprises a zeolite Y which has been ion exchanged with lithium ions and/or rare earth metal ions, and may be dispersed in an amorphous oxide gel matrix.
