摘要： Embodiments of the present disclosure generally relate techniques for abating N2O gas present in the effluent of semiconductor manufacturing processes. In one embodiment, a method includes injecting hydrogen gas or ammonia gas into a plasma source, and an effluent containing N2O gas and the hydrogen or ammonia gas are energized and reacted to form an abated material. By using the hydrogen gas or the ammonia gas, the destruction and removal efficiency (DRE) of the N2O gas is at least 50 percent while the concentration of nitric oxide (NO) and/or nitrogen dioxide (NO2) in the abated material is substantially reduced, such as at most 5000 parts per million (ppm) by volume.

摘要： The exhaust gas purification system includes a SCR, an NOx sensor which is provided on a downstream side of the SCR, and an NOx purifying controller which controls an amount of urea water being ejected to the SCR and performs an abnormality diagnosis based on a detection value of the NOx sensor, wherein the exhaust gas purification system includes an exhaust gas temperature sensor which acquires temperature of the exhaust gas flowing into the SCR, a temperature increasing rate calculating unit which calculates a temperature increasing rate at which the exhaust gas temperature acquired by the exhaust gas temperature sensor reaches a second temperature from a predetermined first temperature, and a prohibiting unit which prohibits abnormality diagnosis by the NOx purifying controller in a case in which the temperature increasing rate calculated by the temperature increasing rate calculating unit is higher than a predetermined determination threshold value.

摘要： An adsorption process for xenon recovery from a cryogenic liquid or gas stream is described wherein a bed of adsorbent is contacted with the aforementioned xenon containing liquid or gas stream and adsorbs the xenon selectively from this fluid stream. The adsorption bed is operated to at least near full breakthrough with xenon to enable a deep rejection of other stream components, prior to regeneration using the temperature swing method. Operating the adsorption bed to near full breakthrough with xenon, prior to regeneration, enables production of a high purity product from the adsorption bed and further enables oxygen to be used safely as a purge gas, even in cases where hydrocarbons are co-present in the feed stream.

摘要： This catalyst system simultaneously removes ammonia and enhances net NOx conversion by placing an NH3-SCR catalyst formulation downstream of a lean NOx trap. By doing so, the NH3-SCR catalyst adsorbs the ammonia from the upstream lean NOx trap generated during the rich pulses. The stored ammonia then reacts with the NOx emitted from the upstream lean NOx trap-enhancing the net NOx conversion rate significantly, while depleting the stored ammonia. By combining the lean NOx trap with the NH3-SCR catalyst, the system allows for the reduction or elimination of NH3 and NOx slip, reduction in NOx spikes and thus an improved net NOx conversion during lean and rich operation.

摘要： A catalyst article having an extruded support having a plurality of channels through which exhaust gas flows during operation of an engine, and a single layer coating or a bi-layer coating on the support, where the extruded support contains a third SCR catalyst, the single layer coating and the bilayer-coating contain platinum on a support with low ammonia storage and a first SCR catalyst. The catalytic articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases and in reducing the amount of ammonia slip. Methods for producing such articles are described. Methods of using the catalytic articles in an SCR process, where the amount of ammonia slip is reduced, are also described.
