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.

Diesel Soot Oxidation

The dipole moments of alkali metal chlorides drive the oxidation of soot by promoting electron transfer, justifying their excellent activities despite their poor redox abilities.
