摘要： Ceramic catalytic compositions, systems, and methods for oxidizing, converting and/or removing NO X gas species present in gas streams such as exhaust gases are provided. The catalysts of the invention oxidize the nitrogen monoxide (NO) in gas streams to nitrogen dioxide (NO 2 ), which may be adsorbed by a metal oxide or other NO 2 adsorber. Catalysts suitable for use in systems of the present invention include ceramic oxides, mixtures of ceramic oxides, complex ceramic oxides, and mixtures of complex ceramic oxides. Such catalysts are shown herein to successfully achieve an NO-NO 2 equilibrium gas composition at temperatures as low as 275°C. In addition, by using the catalyst with an NO 2 adsorber, greater than 95% removal of combined NO and NO 2 from the gas stream has been successfully demonstrated. Further, specific strategies have been identified to regenerate the catalyst system and restore performance after prolonged exposure to species such as sulfur dioxide (SO 2 ).

摘要： A mixed potential sensor device and methods for measuring total ammonia (NH3) concentration in a gas is provided. The gas is first partitioned into two streams directed into two sensing chambers. Each gas stream is conditioned by a specific catalyst system. In one chamber, in some instances at a temperature of at least about 600°C, the gas is treated such that almost all of the ammonia is converted to NO x , and a steady state equilibrium concentration of NO to NO 2 is established. In the second chamber, the gas is treated with a catalyst at a lower temperature, preferably less than 450°C such that most of the ammonia is converted to nitrogen (N 2 ) and steam (H 2 0). Each gas is passed over a sensing electrode in a mixed potential sensor system that is sensitive to NO x . The difference in the readings of the two gas sensors can provide a measurement of total NH3 concentration in the exhaust gas. The catalyst system also functions to oxidize any unburned hydrocarbons such as CH 4 . CO, etc., in the gas, and to remove partial contaminants such as SO 2 .

摘要： A mixed potential sensor device and methods for measuring total ammonia (NH 3 ) concentration in a gas is provided. The gas (12) is first partitioned into two streams (30a and 30b) directed into two sensing chambers. Each gas stream is conditioned by a specific catalyst system. In one chamber (50), in some instances at a temperature of at least about 600°C, the gas is treated such that almost all of the ammonia is converted to NO x , and a steady state equilibrium concentration of NO to NO 2 is established. In the second chamber (40), the gas is treated with a catalyst at a lower temperature, preferably less than 450°C such that most of the ammonia is converted to nitrogen (N 2 ) and steam (H 2 O). Each gas is passed over a sensing electrode in a mixed potential sensor system that is sensitive to NO x . The difference in the readings of the two gas sensors can provide a measurement of total NH 3 concentration in the exhaust gas. The catalyst system also functions to oxidize any unburned hydrocarbons such as CH 4 , CO, etc., in the gas, and to remove partial contaminants such as SO 2 .
摘要翻译：提供了用于测量气体中的总氨（NH 3）浓度的混合电势传感器装置和方法。气体（12）首先被分成两股流（30a和30b），流入两个传感室。每种气流都由特定的催化剂体系调节。在一个室（50）中，在一些情况下，在至少约600℃的温度下，处理气体使得几乎所有的氨都转化为NO x和稳态平衡 NO对NO 2的浓度成立。在第二室（40）中，用较低温度，优选低于450℃的催化剂处理气体，使得大部分氨转化为氮气（N 2）和蒸汽（ ħ<子> 2 O）。每种气体都通过对NO x敏感的混合电位传感器系统中的传感电极。两个气体传感器读数的差异可以提供废气中总NH 3浓度的测量。该催化剂体系还用于氧化气体中的任何未燃烧的碳氢化合物，例如CH 4，CO等，并去除部分污染物如SO 2。 p>

摘要： A mixed potential NO x sensor apparatus for measuring the total NO x concentration in a gas stream is disclosed. The NO x sensing apparatus (10) comprises a multilayer ceramic structure (30, 40, 50, 60, 70), and (80), with electrodes (34) and (84) for sensing both oxygen and NO x gas concentrations and includes screen-printed metallized patterns that function to heat the ceramic sensing element (32) and (82) to the proper temperature for optimum performance. This design may provide advantages over the existing technology by miniaturizing the sensing element to provide potentially faster sensor light off times and thereby reduce undesired exhaust gas emissions. By incorporating the heating source (52) and (54) within the ceramic sensing structure, the time to reach the temperature of operation is shortened, and thermal gradients and stresses are minimized. These improvements may provide increased sensor performance, reliability, and lifetime.
