The present invention provides for a differential electrochemical mass spectrometry (DEMS) cell comprising a working electrode chamber configured such that an electrolyte enters the working electrode chamber through a channel running through the working electrode.

Differential electrochemical mass spectrometry (DEMS) cell

Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.

Methods for producing cyclic and acyclic ketones

Provided herein are methods for producing &#x3b1;,&#x3b2;-unsaturated ketones from the condensation of methyl ketones in the presence of an amine catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The &#x3b1;,&#x3b2;-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such &#x3b1;,&#x3b2;-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.

Methods for producing fuels, gasoline additives, and lubricants using amine catalysts

Provided herein are methods for producing ketone(s) from the condensation of methyl ketone(s) and alcohol(s) in the presence of an amine catalyst and a metal catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketone(s) and/or alcohol(s) may be obtained from renewable sources, such as by fermentation of biomass.

The present disclosure generally relates to the production of fuels, gasoline additives, and/or lubricants, and precursors thereof. The compounds used to produce the fuels, gasoline additives, and/or lubricants, and precursors thereof may be derived from biomass. The fuels, gasoline additives, and/or lubricants, and precursors thereof may be produced by a combination of intermolecular and/or intramolecular aldol condensation reactions, Guerbet reactions, hydrogenation reactions, and/or oligomerization reactions.

Methods for producing fuels, gasoline additives, and lubricants

A method for predicting selective performance of an adsorbent is disclosed. The adsorbent is selected from a list of metals and/or metal cations for use in removing contaminants as thiophene derivatives in hydrocarbon feed. The metals or metal cations are identified from a list having a positive value for E, wherein the metal or metal cation having the largest value for Eis the most selective adsorbent.

Method for predicting adsorbent performance

A process for the production of lower alkyl alkoxyacetates, preferably methyl methoxyacetate, by reaction of a di-(lower alkoxy)methane, preferably dimethoxymethane, with the acid form of a medium-pore or large-pore zeolite catalyst, preferably the acid form of faujasite, ZSM-5, mordenite, or beta, in the gas phase at atmospheric or near-atmospheric pressures.

Process for the production of alkyl alkoxyacetates

Acetic acid is produced by oxidation of methane with an oxygen-containing gas in the presence of an acid selected from concentrated sulfuric acid and fuming sulfuric acid, a palladium-containing catalyst and a promoter, preferably a copper or iron salt. The addition of a promoter and Oto a system that includes a palladium-containing catalyst such as PdClincreases the rate of acetic acid formation from methane by more than an order of magnitude as compared with prior art and, in addition, inhibits the precipitation of Pd black.

Process for direct oxidation of methane to acetic acid

Acetyl anhydrides such as acetyl sulfate are produced by a process for comprising contacting methane and carbon dioxide in an anhydrous environment in the presence of effective amounts of a transition metal catalyst and a reaction promoter, and an acid anhydride compound, and optionally an acid. The acetyl anhydride can be contacted with water to produce acetic acid or with an alcohol to produce a product comprising an acetate ester and that may also comprise acetic acid. Optionally, water in stoichiometric amounts or less, with respect to the acetic anhydride, may be fed to a continuous process of this type to produce some acetic acid in situ.

Process for production of acetyl anhydrides and optionally acetic acid from methane and carbon dioxide

An ionized gas plasma is established in an electrical field in contact with a non-vapor volume monomer (liquid and/or solid). The plasma causes polymerization of the monomers which are of the phosphazene or carborane type.

Polymerization or inorganic element-containing monomers using plasma,

Polymerization of inorganic element-containing monomers using plasma

An ionized gas plasma is established in an electrical field in contact with a non-vapor volume of monomer (liquid and/or solid). The plasma creates active polymerization sites in the monomer volume to initiate propagation of polymerization therein. After initiation, the partially-polymerized monomer volume is postpolymerized in the absence of the ionized gas plasma to yield a very high molecular weight polymer which may be essentially free of cross-linking in desirable forms including commercial quantities of bulk self-supporting polymer or a coating. Suitable monomers include liquid vinyl monomers (e.g., methyl, methacrylate) and solid crystalline monomers (e.g., 1,3,5-trioxane).

Method of plasma initiated polymerization

The present invention relates to a process for preparing high purity inorganic higher oxides of the alkali and alkaline earth metals by subjecting the hydroxide of the alkali or alkaline earth metal to a radio frequency discharge sustained in oxygen. The invention is particularly adaptable to the production of high purity potassium superoxide (KO.sub.2) by subjecting potassium hydroxide to glow discharge sustained in oxygen under the pressure of about 0.75 to 1.00 torr.
