Abstract: An exhaust system for a diesel engine is disclosed. The exhaust system may include a diesel oxidation catalyst (DOC) configured to receive exhaust gases from the engine and oxidize hydrocarbons in the exhaust gases and a passive NOx adsorber (PNA) downstream from the DOC and configured to store NOx from the exhaust gases at temperatures up to 150° C. A selective catalytic reduction (SCR) system may be downstream from the PNA and configured to reduce NOx in the exhaust gases. The PNA may be configured to release the stored NOx at temperatures above 200° C. The DOC upstream of the PNA may reduce the amount of N2O that is generated by the PNA by oxidizing hydrocarbons before they reach the PNA.

Abstract: The invention provides a noble metal-containing supported catalyst which contains one of the noble metals from the group Au, Ag, Pt, Pd, Rh, Ru, Ir, Os or alloys of one or more of these noble metals in the form of noble metal particles on a powdered support material. The particles deposited on the support material have a degree of crystallinity, determined by X-ray diffraction, of more than 2 and an average particle size between 2 and 10 nm. The high crystallinity and the small particle size of the noble metal particles lead to high catalytic activity for the catalyst. It is particularly suitable for use in fuel cells and for the treatment of exhaust gases from internal combustion engines.

Abstract: This invention relates to processes for catalytically oxidizing organic compounds (for example, methane, ethane, propylene and carbon monoxide), catalytically reducing oxides of nitrogen with a reducing fuel as well as for the production of methane by the steam reforming of naphtha and naphtha distillates. The catalyst used in such processes consists essentially of an inert, rigid, porous refractory honeycomb structure coated with a mixture or alloy of platinum, rhodium and a base metal in which rhodium constitutes from 1 - 50 weight % and the base metal constitutes from 0.01 to 25 weight % of the total metal content.
