摘要： A layered catalyst suited to the catalytic cracking of heavy feeds comprises a core and a shell. The shell comprises at least 5 wt % of at least 1 molecular sieve having openings of at least 8 angstroms. The core comprises at least 10 wt % of at least 1 molecular sieve having openings comprising a 12 or less-membered ring and has a reduced, if any, content of said molecular sieve having openings of at least 8 angstroms, relative to its concentration in the shell. Suitable molecular sieve materials having openings of at least 8 angstroms include MCM-41, VPI-5, MCM-9 and layered metal oxides, e.g., pillared clays. The required molecular sieve of the core can include zeolite Y, Ultrastable Y or intermediate pore size zeolites such as ZSM-5. The shell which may further contain a metals passivator can act as a metals sink, and can remove metals from the unit by attrition. The catalyst is preferably prepared by forming the core and then coating or encapsulating the core with a shell material. The shell may also comprise an attritable coating of an amorphous rare earth oxide, aluminum oxide and aluminum phosphate composite, which traps metals.

摘要： A layered catalyst contains a core of at least one, and preferably three, molecular sieve components within a shell layer of reduced molecular sieve content. A preferred catalyst consists of a core of a large pore molecular sieve, preferably a dealuminized Y-type zeolite, a shape selective paraffin cracking/isomerization component, preferably HZSM-5, and a shape selective aliphatic aromatization component, preferably gallium ZSM-5, within a shell of an alumina-rich, matrix. The shell can capture metals from the feeds being processed, it can act as a metals sink, and can remove metals form the unit by attrition. The catalyst is preferably prepared by forming the core and then coating or encapsulating the core with a shell having a reduced molecular sieve content. The shell may contain a pillared clay or other very large pore cracking component. The shell may be an attritable coating of an amorphous rare earth oxide, aluminum oxide and aluminum phosphate composite, which traps metals.

摘要： An improved method for passivating metals in a hydrocarbon feedstock during catalytic cracking has been discovered. The method involves contacting the feedstock with a passivating agent comprising a precipitated porous rare earth oxide, alumina, and aluminum phosphate precipitate. The passivating agent may be coated on a cracking catalyst, be part of the matrix of a cracking catalyst, or be added to the cracking operation as discrete particles.

摘要： The invention describes the preparation of novel cracking catalysts by surface coating conventional cracking catalysts with passivators that act as metals traps. The coating of passivators is weakly bound to the catalyst so as to permit the coating to continuously attrit off during catalytic cracking. The continuous flaking off of the coating exposes a new surface of the coating.

摘要： Agglomerated crystalline zeolites are deagglomerated by treating the zeolite following crystallization. At a point where crystallization is complete, a basic solution is added and/or the temperature of the reaction mass is increased by between 50.degree. and 100.degree. F. Alternatively, the crystalline zeolite is recovered and thereafter treated with a basic solution.

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。

摘要： There is provided a method for synthesizing layered silicates such as magadiite and kenyaite. The source of silica used in this method is freshly precipitated from a silicate solution. For example, this silica source may be obtained by treating an aqueous solution of sodium silicate with sulfuric acid to form an amorphous silica precipitate. This silica precipitate is not dried to reduce its activity prior to use.
