Scaling-up of the catalytic stacked wire mesh filters for the abatement of diesel soot

This work is based on the development of a stacked AISI 304 stainless steel wire meshes structure with oxidizing and filtering capacity, where Co Ce oxide catalysts were deposited surface metallic fibres as novel alternative to current DOC – DPF system. The system was scaled up encouraged by results obtained at lab scale, going from 16 mm filter diameter 130 mm. coated inside case in order conform catalysed diesel particulate (CDPF). A Fiat Palio engine mounted test bench used evaluate capacity scaled-up mesh cartridge. systems developed able reduce matter emitted engines below limits restrained laws. good activity, pressure drop, robustness, versatility low cost designed structures, along adhesion catalytic coating, makes them very promising for filters. • Bench scale stacking discs. fibers. activity would allow passive regeneration filter. Close or lower drop values compared commercial (SiC, ceramic). Robustness, versatility, excellent coating.
