“…In the literature reports, the short channel structures as well as metallic foams have recently been reported as having a great potential as catalyst supports for gas exhaust abatement [12][13][14][15][16]. In our previous works [12,17,18], we reported the superior activity of ion-exchanged Cu/SSZ-13 and Cu/ZSM-5 zeolite catalysts deposited on kanthal plates and foams. In the literature, the deposition of the zeolites onto the metallic supports is performed via dip-coating of the support in the zeolite suspension or zeolite gel [7].…”

Abstract:Metallic supports play an important role as structured reactor internals. Due to their specific properties including enhanced heat and mass transport, high mechanical resistivity and elimination of local hot-spots, they are commonly used in gas exhaust abatement from stationary and automotive industries. In this study, the performance of three structured supports with deposited Cu/USY (Ultrastabilised Y-zeolite) for deNO x abatement were modelled. Based on kinetic and flow resistance experimental results, the one-dimensional (1D) model of structured reactor was developed. The performance of the structured reactors was compared by the length of the reactor necessary to achieve an arbitrary 90% NO x conversion. The performed simulations showed that the sonochemically prepared copper USY and ZSM-5 zeolites deposited on metallic supports may be successfully used as catalysts for deNO x process.

“…13 reveals that the mass transfer coefficient increases with an increase in the feed flow rate for both the Cu ZSM-5 foam catalyst and blank alumina foam. 12,17,41 In heterogeneous reactors, external mass transport can be increased by better mixing of the fluid. The tortuous path of the flow in foam catalysts increases the mixing and enhances the external mass transfer.…”

“…They also confirm that the reduction of NO is a diffusion-limited process and the optimization of support geometry may lead to further enhancement of catalytic performance. The mass transport and kinetics in structured steel foam reactors with Cu ZSM-5 catalysts for SCR of NO x with ammonia were studied by Kryca et al 12,13 Seijger et al studied the in situ synthesis of binderless ZSM-5 on a ceramic foam support and its application in SCR. 14,15 This study focuses on the introduction of a hierarchical micro-mesoporous Cu ZSM-5 catalyst coated on an α alumina foam substrate for standard SCR of NO x by NH 3 .…”

“…They concluded that packed bed reactors offer high mass transfer but with high-pressure drop and monolithic reactors exhibit low-pressure drop but with poor mass transfer. 12 Kryca et al studied NO x SCR by NH 3 and concluded that the structure of the support significantly affects the catalyst performance even for highly active catalysts. They also confirm that the reduction of NO is a diffusion-limited process and the optimization of support geometry may lead to further enhancement of catalytic performance.…”

“…Metal foams are a class of cellular materials with cells randomly oriented and homogeneous in size and shape. Due to their high surface area per unit volume, many authors discussed the properties for a large number of engineering applications, such as condenser for geothermal power plants, groundwater pollution and filters, chemical reactors, vibration control, and energy management, combustion chambers, strain isolation, catalytic beds, air conditioning, and refrigeration systems [1][2][3][4][5][6][7].…”

Metal foams are a material, featuring interesting characteristics for the aeronautical and automotive fields because of their low specific weight, high thermal properties, and mechanical performances. In particular, this paper deals with thermal and fluid dynamic study of 24 open-cell aluminum EN43500 (AlSi10MnMg) metal foams produced by indirect additive manufacturing (I-AM), combining 3D printing and metal casting to obtain a controllable morphology. A study of foam behavior function of the morphological features (pores per inch (PPI), branch thickness (r), and edges morphology (smooth-regular)) was performed. The samples produced were heated by radiation and tested in an open wind circuit gallery to measure the fluid dynamic properties such as pressure drop (Δp), inertial coefficient (f), and permeability (k), in an air forced convection flow. The thermal characterization was performed evaluating both the theoretical (kth) and effective (keff) thermal conductivity of the foams. Also, the global heat transfer coefficient (HTCglobal) was evaluated with different airflow rates. Analysis of variance (ANoVA) was performed to figure out which geometrical parameters are significant during both thermal and fluid dynamic processes. The results obtained show how the controllable foam morphology can affect the involved parameters, leading to an ad hoc design for industrial applications that require high thermo-fluid-dynamical performances.
