  • Patent number: 11571656
    Abstract: This invention relates to a dispersion comprising porous particles dispersed in a liquid phase, wherein the porous particles comprise a zeolite and the liquid phase is a size-excluded liquid. The invention also relates to a method of adsorbing a gas into a liquid, comprising at least the step of bringing the gas into contact with the dispersion. In addition, the invention relates to an assemblage of the dispersion, the zeolite comprising a cavity and a gas contained within the cavity.
    Type: Grant

  • Patent number: 11565212
    Abstract: The invention relates to dispersions of porous solids in liquids selected from deep eutectic solvents, liquid oligomers, bulky liquids, liquid polymers, silicone oils, halogenated oils, paraffin oils or triglyceride oils, as well as to their methods of preparation. In embodiments of the invention, the porous solids are metal organic framework materials (MOFs), zeolites, covalent organic frameworks (COFs), porous inorganic materials, Mobil Compositions of Matter (MCMs) or a porous carbon. The invention also relates to the use of porous materials to form dispersions, and to assemblages of such dispersions with a gas or gases. The dispersions can exhibit high gas capacities and selectivities.

  • Patent number: 11458455
    Abstract: A process for the preparation of a shaped MOF, the process comprising: providing a first reactant comprising at least one metal in ionic form and a second reactant comprising at least one organic ligand capable of associating with said metal in ionic form, and optionally a solvent; allowing the first and second reactants to react to form a MOF; and forming a shaped body directly from the mixture of step b) using an extruder or continuous kneader; wherein the initial ratio of the at least one metal in ionic form to the at least one organic ligand is controlled such that shaped bodies having a minimum defined crush strength are formed without the use of an external binder or lubricant.

  • Publication number: 20210138432
    Abstract: The present invention relates to a process for preparing a magnesium formate based metal-organic framework. The process comprises (a) combining magnesium or magnesium oxide with formic acid; (b) heating the reaction mixture of step (a) at a temperature of between 70° C. and 200° C.; (c) combining formic acid with the reaction mixture of step (b); and (d) heating the reaction mixture of step (c) at a temperature of between 70° C. and 200° C. Steps (c) and (d) may be heated up to 5 times.
