“…The high energy requirements and the increasing demand have been the driving forces to develop new technologies and/or materials which must be cheaper, yet environmentally friendly. Among the competing alternatives towards this end, cyclic adsorption processes such as vacuum pressure swing adsorption (VPSA) [16][17][18][19][20] and simulated moving bed (SMB) [21][22][23] technologies appears to be the most promising and energy-efficient options.…”

The separation of ethylene from ethane is particularly complex due to their similar physical properties. Cryogenic distillation is the most common technology employed for this separation and is one of the most expensive operations in industry, being the driving force for the ongoing research to find a more cost-effective alternative. In the present work, a gas-phase simulated moving bed (SMB) bench unit was employed to produce polymer-grade ethylene from ethane/ethylene mixtures, using binderless 13X zeolite beads as adsorbent, and propane as desorbent. The achieved performance parameters demonstrated the high efficiency of the current technology, since ethylene was obtained with a purity of 99.8%, a recovery of 99.8%, and a productivity of 59.7 kg C2H4 Áh 21 Ám 23 adsorbent . Considering the encouraging results obtained it is fair to say that the gas-phase SMB is a competitive and strong candidate as alternative to the conventional process, especially when combined with enhanced performance adsorbents, such as binderless zeolites.

“…Among the technologies recently developed, the adsorption onessuch as pressure swing adsorption (PSA) [4][5][6][7] and simulated moving bed (SMB) [8,9] are the most promising options to replace the traditional processes in use. For a given adsorptive separation it is of extreme importance to screen and find an "ideal" adsorbent for its success.…”

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.
