Abstract: A method and composition for the removal of contaminants in a gas stream used in the contamination sensitive processes of photolithography and metrology are described. The synergistic effect of a combination of an electropositive metal component, a high silica zeolite, and a late transition metal compound effects removal or reduction of the contaminates in the gas which interfere with light transmittance to the ppb or ppt levels necessary for the gas to be suitable for these uses. The removal of neutral polar molecules, neutral polar aprotic molecules, protic and aprotic alkaline molecules, acidic polar species, and neutral non-polar aprotic molecules is accomplished with the claimed composition. Depending on the type of contaminant, the composition components are each varied from 10 to 80 parts by volume, with the total composition limited to 100 parts by volume.

The lanthanum oxide concentrate is a mixture of lanthanum oxide and one or more oxides from the following group: neodymium oxide, cerium oxide, parseodymiun oxide, strontium oxide, calcium oxide and sodium oxide. The process of manufacture comprises the steps of sintering the lanthanum oxide concentrate, then washing the resultant media. The process of use is the contact of the lanthanum oxide concentrate with an aqueous solution containing arsenic and/or selenium whereby the lanthanum oxide concentrate removes at least a portion of the arsenic and/or selenium from the aqueous solution.

Abstract: A device for purification of exhaust gases of an internal combustion engine capable of achieving combustion of a fuel with lean air-fuel ratios. A NOx-adsorbing mechanism is installed in the exhaust line of the engine. That NOx-adsorbing mechanism can absorb the NOx present in the exhaust gases in the presence of excess oxygen and can release the absorbed NOx when the oxygen concentration of the exhaust gases decreases. The NOx-adsorbing mechanism does not contain any composition capable of acting as an NOx reduction catalyst, and especially no precious metal, and further a three-way catalyst is installed in the exhaust line downstream from the NOx-adsorbing mechanism.
