Methods of oligomerizing hydrocarbons are disclosed. These methods include contacting olefins with an oligomerization catalyst in an oligomerization zone under oligomerization reaction conditions.

Oligomerization of hydrocarbons

A catalyst comprising at least one metal selected from the group consisting of Group 8 metals, Group 9 metals, Group 10 metals and combinations thereof, an organic compound, and a solid acid and a method of making said catalyst is disclosed. The catalyst can be used in a hydrocarbon conversion process.

Hydrocarbon conversion

A process for disproportionating isopentane into isomers of hexane and butane that utilizes a fixed bed reactor employing a catalyst composition comprising aluminum halide. The process additionally includes a product separation zone which can be configured to recover and return at least a portion of the isopentane product stream to the inlet of the disproportionation reactor.

Disproportionation of isopentane

A method of making a composition, said method comprising, spraying a substance comprising platinum and iron into or onto an alumina-containing compound is disclosed. The resulting composition can then be used in a process for oxidizing carbon monoxide with free oxygen.

Process for selective oxidation of carbon monoxide in a hydrogen containing stream

Fluorenyl-containing metallocenes are disclosed along with methods for making the metallocenes. Also disclosed are methods for using the metallocenes as polymerization catalysts. In addition, polymers resulting from such polymerizations are disclosed.

Organometallic fluorenyl compounds, preparations, and use

A composition comprising a promoter and a metal oxide selected from the group consisting of a gallium oxide, an indium oxide, and combinations of any two or more thereof, wherein at least a portion of the promoter is present as a reduced valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.

Desulfurization and novel compositions for same

Metallocene having two cyclic dienyl groups connected by a single carbon having an aryl substituent and a terminally unsaturated hydrocarbyl substituent, olefin polymerization catalyst systems prepared therefrom, and the use of such catalyst systems are disclosed.

Metallocenes, polymerization catalyst systems, their preparation, and use

A composition comprising a promoter and a metal oxide selected from the group consisting of a cerium oxide, a scandium oxide, a lanthanum oxide, and combinations of any two or more thereof, wherein at least a portion of the promoter is present as a reduced valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.

Metallocycle metallocenes are produced by reacting a first metallocene having an aralkyl group or an aryl dialkyl silyl group attached to a cyclodienyl group with about two molar equivalents of an alkali metal alkyl having at least 4 carbon atoms. The use of the metallocycle metallocenes as components of catalyst for the polymerization of olefins is also disclosed.

Metallocycle metallocenes and their use

Metallocenes having a 9-fluorenyl group and another cyclic dienyl group connected by a single carbon having a terminally unsaturated hydrocarbyl substituent wherein the 9-fluorenyl group has a hydrocarbyl substituent in the 4 position, olefin polymerization catalyst systems prepared therefrom, and the use of such catalyst systems are disclosed.

Unsymmetrical unbridged bis-substituted indenyl compounds in which one indenyl is substituted by a 2-aryl or 2-aryl alkyl substituent and the other indenyl is substituted by a terminally unsaturated alkenyl or alkyl substituent in the 1 or 2 position and their use in the polymerization of olefins.

Unsymmetric unbridged bis-indenyl metallocenes and their use

A process for producing a new metallocene comprising reacting a first bridged metallocene which has an olefinically unsaturated with about two molar equivalents of an alkali metal alkyl, catalyst systems resulting from the combination of the resulting metallocenes and a cocatalyst, and polymerization processes using such catalyst systems are disclosed.

Oligomeric metallocenes and their use

Complexes of pyridldiimines with vanadium and other transition metals, and their use as olefin oligomerization and polymerization catalysts
