摘要： A method for activation of an organic cation-containing crystalline catalyst is disclosed. The method includes contacting the catalyst with steam under conditions to decompose the organic cations, which result in the activation of the catalyst. The method has the advantage that organic cations are converted to non-hazardous by-products such as ammonia and light hydrocarbons such as ethylene. These are more easily controlled by environmental control schemes than higher molecular weight by-products resulting from traditional activation methods (nitrogen or nitrogen/air). The steamed catalyst can optionally be calcined to remove any organic material which may remain after steaming.For instance, a major product which results from decomposting the tetraethylammonium organic cations in zeolite .beta. is ethylene. The ethylene can be subsequently converted into carbon dioxide and water by oxidation.
摘要翻译：公开了一种用于活化含有机阳离子的结晶催化剂的方法。该方法包括在分解有机阳离子的条件下使催化剂与蒸汽接触，这导致催化剂的活化。该方法的优点是将有机阳离子转化为无害副产物如氨和轻质烃如乙烯。这些比环境控制方案更容易受到传统活化方法（氮气或氮气/空气）所产生的较高分子量副产物的控制。蒸汽催化剂可以任选地被煅烧以除去蒸汽后可能保留的任何有机材料。例如，由β沸石中的四乙铵有机阳离子分解产生的主要产物是乙烯。乙烯可以随后通过氧化转化成二氧化碳和水。

摘要： Abatement of nitrogen oxides in an industrial exhaust gas is effected by reduction of the nitrogen oxides with ammonia in the presence of a catalyst comprising a porous crystalline siliceous solid such as a ZSM-5 type zeolite. Fast responses to changes of NO.sub.x load is achieved with a zeolite of low to moderate acid activity. The catalyst may be virgin catalyst, aged catalyst previously used for the conversion of a hydrocarbon or an organic compound, or artifically aged catalyst.

摘要： A method is provided for removing trace amounts of organic chlorides from feedstocks by passing the feedstock in contact with a guard bed catalyst comprising shaped particles formed by extruding a mixture of magnesium oxide and a binder inert to the feedstock. The process has particular importance in removing organic chlorides from toluene feedstocks prior to contacting toluene with a disproportionation or alkylation catalyst comprising magnesium-ZSM-5.

摘要： Improved aromatic conversion processes are provided by novel regeneration techniques. Aromatic processes that would benefit from this invention include those processes using catalysts comprising zeolites having a silica to alumina mole ratio of at least about 12 and a constraint index within the approximate range of 1 to 12 and which require regeneration to burn off coke from said catalysts. The improvement of the instant invention resides in conducting said regeneration in the presence of steam under controlled conditions to enhance the activity of the catalysts.
