Abstract:
Method of charging a sorption store with a gas, wherein the sorption store comprises a closed container (10) and a feed device which has a passage (21) through the container wall, through which the gas can flow into the container, and the container has at least two parallel, channel-shaped subchambers (30,31,32,33) which are located in its interior and are each at least partly filled with an adsorption medium (40) and whose channel walls are coolable, wherein, in a first step, gas is fed in in such an amount that a pressure in the store of at least 30% of a predetermined final pressure is reached as quickly as possible and in a second step, the amount of gas fed in is subsequently varied in such a way that the course of the pressure in the store approximates the adsorption kinetics of the adsorption medium (40) until the predetermined final pressure in the store is reached after a predetermined period of time.

Abstract:
Disclosed is a process for preparing a porous metal-organic framework comprising at least one at least bidentate organic compound coordinated to at least one metal ion, where the at least one metal ion is a zinc ion and the at least one at least bidentate organic compound is based on 2-methylimidazole, which comprises the steps (a) addition of a first water-based solution comprising zinc ions to a second water-based solution comprising 2-methylimidazole, with a suspension being formed after addition of the second solution; (b) addition of a third solution comprising a strong base to the suspension formed in step (a).
