我们提出了一个全面的评估的工业，中试规模的原型吸附剂，金属有机框架5（MOF-5）的热物理性质。这些性质是基于M0 F-5的氢吸附系统的设计和建模中的基本成分，并且可以作为开发用于催化、气体分离和吸附其他气体或流体的其他基于M0 F的系统的有用起点。表征的特性包括：填充密度、表面积、孔体积、粒度分布、热导率、热容、抗水解稳定性、H-2吸附的微分焓和Dubininin-Astakhov等温线参数。氢吸附/脱附等温线在跨越77-295 K范围的六个温度下和在0-100巴的压力下测量。(C)2013 Elsevier Inc. All rights reserved.
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 H-2 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. (C) 2013 Elsevier Inc. All rights reserved.
