Wax compositions may be obtained by providing an olefinic feed comprising a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, wherein m and n are independently selected integers each ranging from about 12 to about 100, and the olefinic feed optionally comprises one or more internal olefins and/or one or more branched olefins; contacting the olefinic feed with a metal carbene catalyst in a reactor; forming ethylene and a hydrocarbon substance comprising a linear olefin dimer comprising two carbon atoms less than a sum of m and n; removing the ethylene from the reactor while forming the linear olefin dimer; and isolating a wax composition comprising the linear olefin dimer, a hydrogenated reaction product thereof, or any combination thereof.

Wax compositions comprising linear olefin dimers or hydrogenated variants thereof and methods for production thereof

Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.

Dewaxing using a molecular sieve catalyst

The invention relates to polyoxometalates represented by the formula (A){M'[M&#x2033;MXORH]}or solvates thereof, corresponding supported polyoxometalates, and processes for their preparation, as well as corresponding metal-clusters, optionally in the form of a dispersion in a liquid carrier medium or immobilized on a solid support, and processes for their preparation, as well as their use in reductive conversion of organic substrate.

Polyoxometalates comprising noble metals and corresponding metal clusters

Processes are provided for preparing molecular sieves of framework structure MEI, TON, MRE, MWW, MFS, MOR, FAU, EMT, or MSE. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier L selected from the group consisting of cationic surfactants having a quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars and combinations thereof.

Molecular sieves and a process for making molecular sieves

Processes are provided for preparing molecular sieves. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier L selected from the group consisting of nonionic surfactants, anionic surfactants, sugars and combinations thereof.

Disclosed are novel processes for the production of cyclic imide compounds such as N-hydroxyphthalimide (NHPI). The processes may be particularly well-suited for commercial-scale production of cyclic imides such as NHPI. Such cyclic imide compounds are suitable for use as oxidation catalysts, and specifically may be used to oxidize cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide. Such an oxidation may be particularly useful in a process for the production of phenol and/or cyclohexanone from benzene via a process comprising hydroalkylation of benzene to cyclohexylbenzene, oxidation of the cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide, and cleavage of the cyclohexyl-1-phenyl-1-hydroperoxide to phenol and cyclohexanone. The cyclic imide production process may advantageously include water washing and reactant recovery steps to maximize purity and yield.

Production of cyclic imides suitable for oxidation catalysis

Processes are provided for preparing molecular sieves for use as catalysts. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier which may be selected from cationic surfactants having a single quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars, and combinations thereof.

Process for making molecular sieves

Catalysts and processes for producing catalysts for neopentane production are provided herein. A process includes reducing a catalyst precursor comprising a transition metal and an inorganic support at a temperature less than 500&#xb0; C. to produce a catalyst. Also provided herein are processes to produce neopentane using the catalysts described herein and neopentane compositions produced therefrom.

Catalysts and processes for making catalysts for producing neopentane

Disclosed herein are processes for producing neopentane. The processes generally relate to demethylating isooctane to produce neopentane. The isooctane may be provided by the alkylation of isobutane with butylenes.

Production of neopentane

The invention relates to poly oxometalates represented by the formula (A){M'[M&#x2033;MXORH]}or solvates thereof, corresponding supported polyoxometalates, and processes for their preparation, as well as corresponding metal-clusters, optionally in the form of a dispersion in a liquid carrier medium or immobilized on a solid support, and processes for their preparation, as well as their use in reductive conversion of organic substrate.

Processes for producing neopentane are disclosed herein. Processes comprise demethylating a C-Calkane within a shell and tube reactor to produce a demethylation product including at least 10 wt % neopentane based on the weight of the demethylation product.

Processes to make neopentane using shell and tube reactors

Disclosed herein are processes for producing neopentane. The processes generally relate to demethylating neohexane and/or neoheptane to produce neopentane. The neohexane and/or neoheptane may be provided by the isomerization of C-Cparaffins.

The present invention provides an olefin oligomerization process comprising the steps of: i) reducing the level of acetonitrile in an olefin feed by contacting the feed with a non-zeolitic metal oxide; and ii) contacting the olefin feed with reduced level of acetonitrile with an olefin oligomerization catalyst under conditions suitable to oligomerize the olefin.

Olefin oligomerization process

Peroxo-carbonates derived from molten alkali and/or Group II metal salts, particularly carbonate salts are used as catalysts in oxidation and epoxidation reactions. Transition metal compounds may be included to improve the selectivity of the reactions.
