The useful life of a deactivated inorganic pillared clay catalyst or an inorganic pillared clay sorbent saturated with a steam-distillable organic sorbate is extended by adding a small amount of ammonia to the regeneration gas or to the regeneration steam.

Regeneration of pillared clays with gas containing a small amount of

Highly specific catalyst compositions are provided, comprising zeolites containing a photoassisting material, which is capable of catalyzing photoassisted heterogenous catalytic reactions within the zeolite structure. The photoassisting material can be sorbed by the zeolite or incorporated directly within the zeolitic framework.

Shape-selective photoassisted heterogenous catalyst compositions

A method to isolate the paramagnetic fractions of a sediment to beneficiate the platinum and platinum group element ores therein comprising a differential magnetic filtration separation process.

The migration of a uranium ore body through geologic time may be determined by subjecting the carbonaceous material in host rock to vitrinite reflectance analysis. A substantial variation in the reflectance is an indication of anomalous coalification induced by radiation from uranium ore.

A process for settling sedimentary materials wherein aqueous suspensions thereof are treated with H.sub.2 S as a means for separating clays containing metals associated therewith.

Metals beneficiation process

A method of separating 1,4 cineole from a mixture containing 1,4 and 1,8 cineoles wherein the mixture is contacted with a zeolite having a constraint index of from 0.2 to 12 and having port sizes of approximately 6.7-7.0 angstroms. This causes the 1,4 cineole to be sorbed into the zeolite while the 1,8 cineole is excluded. The zeolite is then separated from the 1,8 cineole so that the 1,4 cineole may be desorbed from the zeolite. This desorbtion may be accomplished by heating the zeolite to a temperature above the boiling point of the cineole or by liquid phase displacement.

This invention relates to a super-active clay catalyst material prepared by a special method for treating clay materials, said catalyst for use in catalytic conversion of organic materials such as, for example, hydrocarbon compounds, heavy crude petroleum stock and kerogen. Said special method comprises contacting a clay material, existing in the raw state as found in nature or synthesized, with a solution containing cations selected from the group consisting of transition metal ions, aluminum ions, hydrogen ions, ions of metals from Group IIB of the Periodic Table of Elements and a combination thereof with each other, said clay material having been maintained at a temperature not exceeding about 100.degree. C. prior to and during the contacting with said solution, and thereafter heating said exchanged clay material to a temperature of at least about 50.degree. C. but not exceeding about 250.degree. C. in the presence of air and/or organic material which is to be catalytically converted. Further, this invention relates to in situ converting organic materials such as, for example, hydrocarbons, heavy crude petroleum stock and kerogen, by contact at low temperature, e.g. from about 50.degree. C. to about 250.degree. C., with said super-active clay material having been prepared in situ or transported thereto.

Super-active clay catalyst and use thereof

This invention relates to an improved method for treating clay materials to prepare a super-active catalyst for use in catalytic conversion of organic materials such as, for example, hydrocarbon compounds, heavy crude petroleum stock and kerogen, wherein when a clay material is contacted with a solution containing cations selected from the group consisting of transition metal ions, aluminum ions, hydrogen ions, ions of metals from Group IIB of the Periodic Table of Elements and a combination thereof with each other, the clay material is in the raw state and maintained at a temperature not exceeding about 100.degree. C prior to and during the contacting with said solution and thereafter heating said exchanged clay material to a temperature of at least about 50.degree. C but not exceeding about 250.degree. C in the presence of air and/or organic material which is to be catalytically converted. Further, this invention relates to the clay material which is the product of the above improved method and to converting organic materials such as, for example, hydrocarbons, heavy crude petroleum stock and kerogen, by contact at low temperature, e.g. from about 50.degree. C to about 250.degree. C, with said clay material.
