摘要： A method is provided for reducing NO.sub.x for high flow applications such as NO.sub.x abatement in an exhaust gas from an internal combustion engine operating under lean burn conditions wherein NO.sub.x is reduced by hydrocarbon reductants. The method employs a hydrothermally stable catalyst comprising transition metal-containing ZSM-5 which is prepared by in-situ crystallization of an aggregate comprising ZSM-5 seeds, silica, and a crystalline silicate.

摘要： There is provided a method for preparing a zeolite other than ZSM-5 from a reaction mixture comprising a mixed organic directing agent which is a combination of (a) an organic nitrogen containing compound such as an amine or a quaternary ammonium compound and (b) an alcohol and/or diol. Particular zeolites synthesized by this method include ZSM-22 and ZSM-23. The use of an alcohol or a diol may inhibit the coformation of ZSM-5. Especially when used to prepare ZSM-23, this method enables the preparation of more catalytically active ZSM-23 of reduced crystallite size and also enables the use of lower crystallization temperatures. Particular mixed organic directing agents for the preparation of ZSM-23 are combination of (a) pyrrolidine and (b) ethanol or ethylene glycol. Other factors which enhance the activity of ZSM-23 include the use of the following in the reaction mixtures for preparing ZSM-23: potassium ions; precipitated silica particles as sources of silica; and spray dried precipitated silica/alumina particles as sources of silica and alumina. The catalytic stability of alumina bound ZSM-23 catalysts is especially enhanced by steaming. Particular reactions which can be catalyzed by ZSM-23 made according to methods described herein include the dealkylation of ethylbenzene and the alkylation of benzene with ethylene.
摘要翻译：提供了一种从含有（a）有机氮化合物如胺或季铵化合物的组合的混合有机导向剂的反应混合物制备ZSM-5以外的沸石的方法，（b）醇和/或二醇。通过该方法合成的特定沸石包括ZSM-22和ZSM-23。使用醇或二醇可能会抑制ZSM-5的共形。特别是当用于制备ZSM-23时，该方法能够制备更小的微晶尺寸的更具催化活性的ZSM-23，并且还能够使用较低的结晶温度。用于制备ZSM-23的特殊混合有机导向剂是（a）吡咯烷和（b）乙醇或乙二醇的组合。提高ZSM-23活性的其他因素包括在制备ZSM-23：钾离子的反应混合物中使用以下物质：沉淀二氧化硅颗粒作为二氧化硅来源; 和喷雾干燥的沉淀二氧化硅/氧化铝颗粒作为二氧化硅和氧化铝的来源。氧化铝结合的ZSM-23催化剂的催化稳定性通过蒸汽特别提高。根据本文所述方法制备的可以由ZSM-23催化的特定反应包括乙苯的脱烷基化和苯与乙烯的烷基化。
