We present a comprehensive assessment of the thermophysical properties of an industrial, pilot-scale version of the prototype adsorbent, metal-organic framework 5 (MOF-5). These properties are essential ingredients in the design and modeling of MOF-5-based hydrogen adsorption systems, and may serve as a useful starting point for the development of other MOF-based systems for applications in catalysis, gas separations, and adsorption of other gasses or fluids. Characterized properties include: packing density, surface area, pore volume, particle size distribution, thermal conductivity, heat capacity, stability against hydrolysis, differential enthalpy of H2 adsorption, and Dubinin-Astakhov isotherm parameters. Hydrogen adsorption/desorption isotherms were measured at six temperatures spanning the range 77-295 K, and at pressures of 0-100 bar.
