Abstract: SCR-active molecular-sieve based catalysts with improved low-temperature performance are made by heating a molecular-sieve in a non-oxidizing atmosphere with steam (hydrothermal treatment), or in a reducing atmosphere without steam (thermal treatment), at a temperature in the range of 600-900° C. for a time period from 5 minutes to two hours. The resulting SCR-active iron-containing molecular sieves exhibit a selective catalytic reduction of nitrogen oxides with NH3 or urea at 250° C. that is at least 50% greater than if the iron-containing molecular-sieve were calcined at 500° C. for two hours without performing the hydrothermal or thermal treatment.

Abstract: Certain embodiments herein relate to methods of increasing a reaction chamber batch size. A portion of a batch of wafers is processed within the chamber. The processing results in at least some off-target deposition of material on interior surfaces of the reaction chamber. A mid-batch chamber processing is conducted to stabilize the off-target deposition materials accumulated on the chamber interior surfaces. Another portion of the batch of wafers is processed within the chamber. In various embodiments, processing of the chamber (e.g., mid-batch) and subsequent portion of the batch of wafers is repeated until processing of all wafers is complete. Batch size refers to the number of wafers that may be processed in the reaction chamber between chamber clean cycles. Chamber interior surfaces are seasoned prior to batch processing. Seasoning of the chamber interior surfaces involves applying a coating of the same material that may be used for deposition on the wafers during processing of the same.
