Abstract: Uranium oxide or uranium and silver oxides in combination with hydrogen or rare earth oxides are exchanged into zeolites as components of zeolite cracking catalysts to increase the olefin content of the gasoline and, thus, enhance the yield of high octane components as well as reduce the coking tendency of the catalyst.

Abstract: This invention relates to an improvement in the process of preparing porous ceramic articles which are formed by blending a composition containing a polyolefin, a ceramic filler and a plasticizer; shaping the blend; extracting the plasticizer and firing the article to remove the polyolefin. The improvement comprises soaking the extracted article in a water solution of a surfactant prior to firing which results in a substantial reduction in the number of cracked pieces when firing many pieces simultaneously.

Abstract: An amorphous hydrocarbon cracking catalyst of high activity is prepared by mixing solutions of sodium silicate and sodium aluminate, allowing the gel and age, acidulating said gel to precipitate the excess aluminate and ion exchanging after drying to accomplish removal of the alkali metal.

Abstract: A process for preparing a hydrocarbon cracking catalyst is disclosed. The process consists of preparing a silica sol by passing sodium silicate through an ion exchange resin column to form a silica sol containing about 5% silica. Clay and zeolitic components are added and the product is spray dried. This process is advantageous in that it produces a more dense and hence more attrition resistant catalyst.

Abstract: A process for the preparation of phosphate-containing extruded alumina catalyst supports is disclosed. Due to their particular characteristics, these supports find application in hydrocarbon conversion catalysts and especially in catalysts for the hydrotreating of petroleum feedstocks.

Abstract: An ultra thermal stable zeolite aluminosilicate having a silica to alumina ratio of 2.5 to <3.5 and a process of making this composition characterized by ammonia ion exchange, followed by calcination at from 1000.degree. to 1400.degree.F. The composition is further characterized by sodium content expressed as the oxide of less than 4 percent.

Abstract: A process for preparing a synthetic ferrierite having the absorption and catalytic properties characteristic of 5 to 8 angstrom zeolites which comprises treating a reaction mixture consisting of strontium, calcium and/or sodium, lithium or magnesium salts, a source of silica and a source of alumina and water with natural or synthetic ferrierite seeds and heating to convert the mass to the synthetic ferrierite.

Abstract: A novel mixed rare earth-transition metal exchanged faujasite is prepared by exchanging alkali metal faujasite with a mixture of rare earth and transition metal salts at a pH of about 3.5. The novel faujasite, which contains 0.2 to 3% transition metal and 2 to 14% rare earths, (both ranges expressed as oxides), is used as a hydrocarbon conversion catalyst or as a component in a zeolite promoted hydrocarbon conversion catayst.

Abstract: A gaseous or liquid sampling collection unit designed to prevent loss of any of the matter collected and designed to prevent the accidental or intentional loss of all or part of the amount of matter collected, consisting of a filter capsule comprising a shield, and a filter, a two piece cassette containing said capsule consisting of an upper member and a close fitting lower member wherein the capsule is positioned between the upper and lower members of said cassette, the upper member of said cassette containing a valving arrangement permitting a unidirectional flow and, a tamper proofing plate preventing the accidental or intentional interference with the collection function.

Abstract: A porous ceramic monolithic structure prepared by shaping a ceramic filled polyolefinic material containing a plasticizer, shaping, extracting the plasticizer and treating to remove the polyolefin. The monolithic structure is characterized by uniform pore openings. It has uniform channels of an essentially rectangular cross section, laterally through the length of the monolith, varying in size from 0.025 to 0.20 inches.

Abstract: In a two-stage catalytic treatment of engine exhaust gases a monolithic catalyst structure having a first catalytic section concentric within a second catalytic section, the first and second sections being in spaced apart relation for nearly the entire length of the monolith. The structural arrangement aids in reducing the possiblity of catalyst breakage.

Abstract: A process for preparing a hydrocarbon cracking catalyst which consists of preparing a silica hydrosol, adjusting the pH of the sol and at the same time buffering the sol by adding an aluminum sulfate solution, adding clay and zeolitic components, spray drying, washing with water, rare earth exchanging if desired and recovering the product. The catalyst is characterized by excellent attrition resistance and activity.

Abstract: A kilovoltmeter capable of indicating potentials in the kilovolt range is disclosed. The device is based on the phenomenon of electroosmosis engendered by a strong electric field.

Abstract: The methanation reaction, that is, the conversion of carbon monoxide and hydrogen to methane and a water byproduct is conducted at a temperature of 120.degree. to 500.degree.C and a pressure of 100 psig to 2000 psig in the presence of a catalyst consisting of nickel oxide and cobalt oxide in a nickel/cobalt ratio of 1 to 1.5 supported on a high purity alumina support consisting essentially of gamma alumina. The catalyst has a surface area of about 100 to 200 m.sup.2 /g, an average pore diameter of 100 to 115A and a pore volume of 0.25 to 0.7 cc/g.

Abstract: The invention disclosed is for a process of preparing sintered ceramic structures, which includes heating a green ceramic body formed of a sinterable ceramic moiety composited with a heat decomposable combustible organic binder to decompose at least a substantial portion of the organic binder, the decomposition being effected at a temperature below the sintering temperature of the ceramic moiety, the heating being effected while the body is within a zone sufficiently low in free oxygen concentration to substantially prevent flame propagation at the surface of the ceramic moiety; and thereafter heating to sinter the ceramic moiety to form a sintered ceramic structure.

Abstract: A process for preparing a catalyst that has improved activity and efficiency for conversion of hydrocarbons is disclosed. The catalyst is prepared by applying sulfito complexes have the emperical formula M.sub.6 (x) (SO.sub.3).sub.4 where M is H+ NA+, K+ or NH.sub.4 + and x is platinum, palladium or mixtures thereof. In addition, the compounds M.sub.2 (x) (SO.sub.3).sub.2 and M.sub.2 (x) (SO.sub.3).sub.2 also have utility in our process. The complex salt is impregnated onto a support and activated by calcination in air or heating in a reducing atmosphere.
