NOVELTY - Making adsorbent body comprises: (a) contacting adsorbent material with initial mixture to form solvated adsorbent mixture in first solvent, where the adsorbent material is metal-organic frameworks or its precursors, covalent-organic frameworks or its precursors, zeolites, activated carbon, and/or organic cages, and the initial mixture comprising polymeric organic binder and first solvent, where the solvated adsorbent mixture having adsorbent material, polymeric organic binder and first solvent, and the polymeric organic binder is adsorbed onto the surface of the adsorbent material, where the first solvent is distributed throughout the solvated adsorbent mixture; (b) removing at least some of the first solvent from the solvated adsorbent mixture in the first solvent to form initial adsorbent body; (c) contacting the initial adsorbent body with second solvent to form reduced-binder adsorbent body; and (d) solvent-drying the reduced-binder adsorbent body to form the adsorbent body. USE - The process is useful for making adsorbent body, which is used as gas storage, preferably carbon dioxide or hydrogen storage (all claimed) in vehicular fuel tanks. ADVANTAGE - The process provides adsorbent body, which has: envelope density of greater than 0.3 g/cm3; relative density of 0.3-1.2; Brunauer-Emmett-Teller area of greater than 100 m2/g; micro-porosity of greater than 40% of the total pore volume as measured by nitrogen adsorption; macro-porosity of less than 15% as measured by mercury porosimetry; and robust, resistant to attrition, high performing, high density, high surface area, desirable porosity profile with high levels of micro and meso-porosity, and relatively low level of macro-porosity. DETAILED DESCRIPTION - Making adsorbent body comprises: (a) contacting adsorbent material with initial mixture to form solvated adsorbent mixture in first solvent, where the adsorbent material is metal-organic frameworks or its precursors, covalent-organic frameworks or its precursors, zeolites, activated carbon, and/or organic cages, and the initial mixture comprising polymeric organic binder and first solvent, where the solvated adsorbent mixture having adsorbent material, polymeric organic binder and first solvent, and the polymeric organic binder is adsorbed onto the surface of the adsorbent material, where the first solvent is distributed throughout the solvated adsorbent mixture; (b) removing at least some of the first solvent from the solvated adsorbent mixture in the first solvent to form initial adsorbent body; (c) contacting the initial adsorbent body with second solvent to form reduced-binder adsorbent body, where during step (c) from at least 20-80wt.% of the polymeric organic binder is removed from the initial adsorbent body and is dissolved into the second solvent, where the reduced-binder adsorbent body comprising adsorbent material, polymeric organic binder, second solvent and residual first solvent, and the polymeric organic binder is adsorbed onto the surface of the adsorbent material, where the second solvent is distributed throughout the reduced-binder adsorbent body; and (d) solvent-drying the reduced-binder adsorbent body to form the adsorbent body, where the solubility of the polymeric organic binder in the first solvent is the same or higher than the solubility of the polymeric organic binder in the second solvent. An INDEPENDENT CLAIM is also included for adsorbent body made to the process.
