    摘要： Ethylbenzene is produced by the alkylation of benzene with ethylene in the presence of an alkylation catalyst having a particular structure defined by its X-ray diffraction pattern. A preferred catalyst is the zeolite MCM-22. The process is typically carried out at a temperature of 300.degree. to 1000.degree. F. but the catalyst provides sufficient activity for the reaction to be carried out at temperatures below 700.degree. F. Liquid phase operation is preferred, giving a lower yield of polyethylated products. The use of the selected catalyst also results in a reduction of the xylene impurity level to values below 500 ppm in the product.

    摘要： Layered silicate materials of high thermal stability and surface area which contain interspathic oxides such as silica as prepared by treating a layered silicate, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming said oxide, is thereafter introduced between the layers. The resulting product is treated to form the oxide, e.g. by hydrolysis, to produce the layered silicate material. The resulting product may be employed as a catalyst material in the conversion of hydrocarbons.

    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 hydrous aluminosilicate adsorbent composition in which the active adsorbent is a mixture of non-fibrous clay with non-fibrous zeolite. The composition is useful as a feed supplement in animal husbandry, and as a topical adsorbent for veterinary use. The mixture has a high capacity for adsorption of ammonium cations, and a synergistically high selectivity for their adsorption. Beneficial effects as feed supplement may arise from lowering the amount of ammonia passed to the liver from the alimentary canal.

    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.
