Quasi-Continuous Particle Trap Regeneration by Cerium-Additives

Hydrogen-reduced Cu/ZnO composite as efficient reusable catalyst for diesel particulate matter oxidation

“…A catalytic diesel particulate filter is the best solution at present to reduce particulate matter emissions from diesel engines, where the particulate matter is trapped and oxidized with the help of a catalyst at temperatures below 600 • C. The only problem associated with this filter is the poor contact between the catalyst surface and the particulate matter [8,9]. Though several catalysts and technologies have been proposed to control this problem, the so-called fuel-borne catalysts (FBC), consisting in organometallic fuel additives, has seen to perform effectively in DPF, for the oxidation of particulate matter at lower temperatures [10,11]. However, the application of FBC is strongly restricted due to its continuous consumption and the accumulation of metal oxide as ash inside DPF.…”

Synthesis, Characterization of Ceria Modified ZSM-5 and Its Performance Towards NO Oxidation

“…For example, if we add cerium compound as fuel additive first they decrease the engine-out particulate [18]. The second effect of the cerium additive is that it enhances the reactivity of the soot formed [19][20][21].…”

RECP: A Reactor Designed to Test the Effect of a Catalyst on Soot Oxidation in a Diesel Particulate Filter

“…The rate of soot combustion in the presence of oxygen is slow at the temperature of the exhaust gas (from 100 C to 450 C). To increase the rate of soot oxidation in this temperature range, a catalytic material can be used in two possible ways: as an additive present within the soot (fuel-borne additives) [2,3], or present on a filtration area coated with a catalytic layer [4±6].…”
