“…The BET surface area of MIL-100(Fe) powder was 1772 m 2 /g with a total pore volume of 0.93 cm 3 /g (P/ P 0 = 0.99); however due to the addition of a binder, the BET value of the MIL-100(Fe) granule slightly decreased to 1619 m 2 /g, and the total pore volume also decreased to 0.82 cm 3 /g (P/P 0 = 0.99). The MIL-100(Fe) granule in this study showed a much lower BET decrease ratio (8.6%) compared to the granule previously reported in the literature (33.6%) prepared using the press method [39].…”

“…S2, the pore size distributions of the powder and granule show similar profile with the exception of a small reduction in pore volume that possibly originated from the content of the binder. It indicates that the micropore volume of MIL-100(Fe) decreased less during the granulation process unlike the press or extrusion method reported in previous literatures [39][40][41].…”

“…The estimated annual total CO emission from industry is over 50 Mt in China (Lu ). However, in the flue gases, CO is generally presented in gas mixtures, such as CO/N 2 mixture in carbon black tail gas and blast furnace gas (García et al 2012, Munusamy et al 2012. Therefore, the separation and purification of CO from gas mixtures play a vital role for CO recycling and utilization.…”

The objective of this work is to develop CuCl@AC adsorbent with high CO capacity and selectivity from CO/N 2 binary gas mixture. A series of CuCl@AC adsorbents were prepared by a solid-state auto dispersion method, and then characterized by N 2 adsorption test, XRD and XPS. CO and N 2 adsorption isotherms on the adsorbents were measured by a volumetric method. The adsorption isotherms and selectivities of CuCl@AC adsorbents for CO/N 2 binary mixture were estimated on the basis of ideal adsorbed solution theory (IAST). Results showed that (a) CO uptakes of CuCl@AC increased with CuCl loading in the loading range of 0-1.2 g/g. The maximal CO adsorption capacity of the CuCl@AC with CuCl loading of 1.2 g/g reached 38 cc/g at the P/P 0 of 0.40, around 8 times of that over the original AC; (b) calcination time for the preparation of Cu(I)@AC had significantly impact on CO adsorption of the adsorbents due to valence change of Cu species on carbon surfaces. XPS analysis indicated that when the calcination time was optimized to be 1 h at 350°C under argon, the prepared Cu(I)@AC had the highest percentage of Cu ? species on its surfaces, and consequently it had the highest CO capacity among the adsorbents since adsorptive species responsible for CO adsorption is Cu ? ; (c) The IAST-predicted CO/N 2 adsorption selectivities of 1.2CuCl/AC decreased with pressure. Its CO/N 2 selectivity was up to 100-450 at low pressure range of 0-10 kPa, and it remained in the range of 50-100 at higher pressure range of 20-100 kPa. The high adsorption capacity and selectivity of Cu(I)@AC adsorbents made it a promising adsorbent for CO/N 2 mixture separation.

IntroductionShaping and forming of metal-organic frameworks (MOFs) are essential for practical applications like adsorption/separation and catalysis, which require structuring of the nano-/microcrystalline fine powders of MOFs into a macroscopic body [1][2][3][4][5][6][7]. When a process for catalysis or adsorptive separation is scaled up to the pilot or commercial scale, the form in which an active catalyst or adsorbent is used is decisive in determining the ultimate performance of the unit [8][9][10]. In this respect, the size and shape of the target material require a compromise between minimizing pore diffusion effects in the material particles, for which small particles are necessary, and minimizing the pressure drop across the reactor, which requires large particle sizes [11]. The shaped MOFs should maintain excellent performance shown by the original powder forms based on their high porosity, crystallinity, and flexibility [12]. Therefore, the proper selection of the shaping or forming process is important in the MOF research field for chemical engineering and industrial applications. As the shaping methods are often proprietary and often more of an art than a science, the exact procedures are rarely disclosed.The shaped MOFs can also be prepared using techniques (Figure 18.1) that have typically been utilized for synthesizing catalysts and adsorbents from porous materials, such as pressing, extrusion, granulation and spray drying, foaming, casting, and coating. Well-shaped bodies have been produced in the forms of pellets, tablets, monoliths, granules, and spheres [13][14][15][16]. However, to utilize shaped MOFs successfully for industrial applications, they should have sufficient mechanical strength, chemical stability, attrition resistance, maximal bulk density, and minimal wasted space in the storage vessel [17][18][19][20][21][22][23][24]. As the performance of shaped MOFs for industrial or large-scale applications depends on several parameters, including the mass-and heat-transfer properties, gas diffusion kinetics, pressure drop across material, mechanical strength, and volumetric efficiency, achieving high mechanical integrity of the structured MOF is critical to the performance in real engineering processes.
