Low Temperature Microwave Regeneration of Catalytic Diesel Particulate Filter

Blog Article

Diesel particulate filter (DPF), consisting in alternately plugged parallel square channels with porous walls that trap the soot particles, must be periodically regenerated.In this work, a new procedure for the preparation of NEFF B57VS24H0B N90 HIDE AND SLIDE OVEN microwave susceptible catalytic DPFs based on a preliminary controlled chemical erosion of the porous structure was optimized, so obtaining catalytic filters with higher catalyst Christmas Decor load (30 %wt CuFe2O4).The filters showed pressure drop values very similar to that pertaining to the uncatalysed filters and a higher regeneration activity: consequently their microwave assisted regeneration phase, compared to the traditional fuel post-injection, allowed an energy saving of about 60 %.
