Diesel oxidation catalyst (DOC)The HC and CO oxidation activity of Pt/Al2O3, Pd/Al2O3 and Pd-Pt/Al2O3 catalysts was compared under three exhaust-gas model conditions typical for stoichiometric gasoline as well as lean burn diesel by means of temperature programed conversion tests on ...
According to the present invention, a composite metal oxidation catalyst comprising cerium (Ce), zirconium (Zr), copper (Cu) and silver (Ag) is more economical and thermally stable than platinum group metal catalyst, which is known to have excellent performance, and is excellent in removal ...
The first carbon supported catalyst 48 has a first average micropore 42 diameter, and a first average surface area. The first carbon supported catalyst 48 is contacted with an oxygen-containing gas at a temperature less than about 250掳C for a predetermined period of time to form a second ...
A carbon supported catalyst includes a carbon support having an average micropore diameter is less than about 70 angstroms and a platinum-group metal being disposed over the carbon support. A method for making the carbon supported catalyst includes a step of providing a first carbon supported ...
A method for making the carbon supported catalyst includes a step of providing a first carbon supported catalyst having a platinum-group metal supported on a carbon support. The first carbon supported catalyst has a first average micropore diameter, and a first average surface area. The first ...
A method for forming a carbon supported catalyst includes a step of providing a first carbon supported catalyst having a platinum-group metal supported on a first carbon support. Characteristically, the first carbon support has a first average micropore diameter and a first average carbon surface ...
