“…The calcination of the stainless steel wire mesh structures at 900 °C for 1 h produced an average increase in weight of 0.20% due to the generation of an oxidic layer, which was composed of spinel structures of Mn, Fe, and Cr, as observed in a previous study [13]. This rough oxidic layer resulted in being well adhered on the surface of the wire meshes, enhancing the thermal stability of the substrate and allowing catalyst anchoring, which shows the importance of this pretreatment prior to the catalyst deposition [31][32][33].…”

“…Figure 1a shows photos of the cut meshes with the stamped channel and the empty cylinder used to build the stacked wire mesh monoliths (Figure 1b). Details of the construction steps for this type of metallic monoliths are given elsewhere [1,2,13]. The disposal of the wire meshes allowed obtaining a tortuous structure capable of filtering soot and favoring reactant mixing.…”

“…In particular, wire mesh structures represent a versatile system that can adopt different geometries [12] making them applicable to several industrial and environmental processes. A great variety of wire meshes exist, the more important properties being the mesh opening, the wire diameter, and the material used [2,13,14]. These types of structures have been used in different reactions for volatile organic compound (VOC) combustion [2,15], photocatalysis [16,17], selective catalytic reduction (SCR) of NO x [18], and also in physical processes, such as oil-water separation [19].…”

Structured catalysts based on Pt,CeO 2 deposited on stainless steel wire meshes were developed to build catalytic cartridges for the treatment of diesel exhaust gases. The cartridges were tested for the simultaneous combustion of volatile organic compounds (VOCs) and soot. To this end, n-hexane, acetyl acetate, and toluene were selected as probe molecules. Each of them were loaded together with real soot into the cartridges showing that while VOCs abatement takes place between 200 • C and 350 • C, soot combustion occurs in the 300-500 • C temperature range with an average maximum combustion rate at 420 • C. The catalytic cartridges were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and Brunauer-Emmett-Teller (BET) techniques. The mechanical stability of the coatings was confirmed by the ultrasound method. Air permeability of the cartridges prepared with different mesh sizes was also measured and the results were correlated using the Payri equation.

Potassium‐Activated Wire Mesh: A Stable Monolithic Catalyst for Diesel Soot Combustion

et al. 2016

Potassium-modified FeCrAl alloy wire mesh was developed as a catalytic diesel particulate filter to suppress the emission of soot from a diesel engine. Potassium species were deposited on wire mesh by a chemical vapor deposition method, in which a model soot was used to convert KOH into metallic K at high temperatures to subsequently activate the wire mesh. Tests showed that metallic K reacted with the enriched Al 2 O 3 component on the surface derived from segregation and successive oxidation during precalcination. The resulting layer of K-O-Al species offers remarkable activity and stability for the catalytic oxidation of diesel soot. The K-activated wire mesh could lower the initial temperature of soot combustion and maintain the activity for several cycles.
