Patent ID: 7785702

Claim:
A storage unit for the sorptive storage of gases, said storage unit comprising: a sorbent for the reversible uptake of the gases to be stored, said sorbent being based on discrete sorptive particles wherein the sorptive particles have a grain shape, the mean particle diameter being in the range of from 0.01 to 2.0 mm; and a solid gas-permeable three-dimensional support of foam material, said foam material having an original volume that is loaded with said discrete sorptive particles and said foam material having a compressed volume in a ratio of original volume/compressed volume from between 1.2/1 to 3/1, said compressed volume state being maintained as a result of being cured wherein said foam material is impregnated with a chemical curing agent and subsequently cured in the compressed volume state, the curing agent being adhesive means which at the same time serves to fix the sorptive particles to the foam material, wherein the foam material is loaded with the sorptive particles subsequently to the impregnation with the curing agent and prior to the curing in the compressed volume state.
