Summary: In this study, heavy-oxygen water was used to investigate the influence of water on soot oxidation in automobile exhaust. It was found that water participated in the oxidation process, acting as an accelerator rather than an oxidant. The promotional effect of water on activity was observed in all conditions, likely due to its ability to dissociate into more active oxygen species and facilitate oxygen vacancies regeneration.

Summary: A Mn2O3 catalyst was found to exhibit efficient soot oxidation in gasoline exhaust, both in model exhaust with Mn2O3/soot mixtures and in a gasoline engine test bench with Mn2O3-coated particulate filter. The mechanism of oxygen transport from gas phase to soot was investigated, suggesting dissociative adsorption and surface migration of O2 on Mn2O3, followed by transfer of oxygen to soot at physical contact points. The role of surface, sub-surface, and bulk oxygen in the catalyst was also observed, with enhanced participation of bulk oxygen due to declining O2 content.

Summary: Through isotopic studies on model catalysts, it was found that doping with Ce and Pr elements can promote oxygen exchange and increase oxygen mobility, thereby achieving soot removal. Different synthesis methods can affect the way oxygen migrates in different centers, while the presence of NO can enhance soot removal capacity through the intervention of adsorbed products.

Summary: Accurate prediction of soot formation and evolution is difficult due to the complex interaction between gas-phase composition and solid-phase particles. The choice of gas-phase mechanisms significantly affects predictability. A systematic analysis of nine ethylene combustion mechanisms shows large differences in fundamental chemistry and polycyclic aromatic hydrocarbon (PAH) chemistry. The various mechanisms lead to significant differences in predicting soot concentrations, indicating the need for calibration or improvement of fundamental chemistry.

Summary: A series of Ce1-xTixO2 mixed oxide catalysts were synthesized using sol-gel method and noble metal loading for soot oxidation. The Ti-doped Ce1-xTixO2 catalysts exhibited better oxidation performance than CeO2, with the Ce0.9Ti0.1O2 catalyst showing the highest catalysis activity when calcined at 500 degrees C. The introduction of Ti into CeO2 enhanced the catalytic activity and increased the number of oxygen vacancies on the catalyst surface. Noble metals dispersed over Ce0.9Ti0.1O2 showed enhanced activity compared to Ce0.9Ti0.1O2. A small amount of Ti doping improved the catalyst activity, while excessive Ti reduced performance due to hindered contact and reaction with soot.

Summary: This study investigates NOX reduction by H-2 under O-2-rich conditions using Al2O3/SiO2-supported Pt catalysts with different loads of WOx promotor. The results show that smaller Pt particles are more efficient, while the introduction of WOx increases deNOX activity and N-2 selectivity. The promoting effect is attributed to an additional reaction path at the Pt-Wo(x)/Al2O3/SiO2 interface.

Summary: This study investigates the mechanisms behind the consecutive adsorption of H2S and O2 on iron oxides/hydroxides, revealing dissociation of H2S at different surface sites and the consumption of the adsorbent. The findings suggest that complete regeneration of the iron substrates is almost impossible due to their substantial degradation, with partial conversion into sulfates and the deposition of sulfur as by-products.

Summary: This paper describes a novel design of an AdBlue mixing unit that reduces urea deposits in diesel exhaust at low temperatures. The design includes the injection of AdBlue in an axisymmetric swirling flow, achieved by splitting the exhaust stream and off-centred introduction of the sub-flows. Computational fluid dynamics simulations were used to analyze important geometric parameters such as pressure loss, flow field, and spray morphology. The effectiveness of the design was confirmed through experimental investigations on multiple levels, including an optical test bench, a diesel engine test bench, and a hydraulic excavator. The experiments demonstrated that the AdBlue mixer effectively prevents deposits and critical back pressure.
