Soot Oxidation Activity

A Co3O4/Sn–CeO2 hybrid catalyst exhibited superior soot oxidation activity due to the existence of synergism among the multivalent cations and the stepped surface of the hybrid catalyst.

Catalyst Systems

The catalysts based on V/K/Ca and V/Ks/Ce systems for diesel soot catalytic oxidation were synthesized onto the porous alumina substrates. Both catalyst systems showed a good catalytic oxidation activity. The V/K/Ca system exhibited the lowest oxidation onset temperature (OOT) of about 359oC with a composition of V/K/Ca =1:1:0.1 where the V and Ca and/or K elements could form a kind of amorphous phase that determined the catalytic activity. The V/Ks/Ce system displayed the lowest OOT of about 350oC with a composition of V/Ks/Ce = 1:2:0.1 where the K2SO4 and K5V2O3(SO4)4 phases could contribute most to the catalytic activity.

Abstract In the present research, CeO2 and CuO/CeO2 nanofibers were synthesized by electrospinning at 12 kV DC by maintaining a tip to collector distance of 10 cm. The morphology of the as-synthesized nanofibers was determined by scanning electron microscopy, and their elemental composition was verified by X-ray photoelectron spectroscopy. The activity of the prepared samples for diesel soot oxidation was determined in a bench-scale fixed bed tubular reactor, and effluent gases were analyzed by online gas chromatography. The variations of working parameters (air flow rate, catalyst-soot ratio, catalyst-soot contact type) were evaluated in a range to optimized reaction conditions for diesel soot oxidation. The catalyst with 40% CuO/CeO2 had the highest surface area, the smallest crystallite size, and the best activity for diesel soot oxidation (tight contact) at Tf = 318oC.
