A process comprising catalytically converting ethane to ethylene and acetic acid in the presence of oxygen at a temperature of 450&#xb0; C. or less in the gas phase wherein the catalyst has the empirical formula MoVNbTeZO.

Process for making ethylene and acetic acid

The application concerns a process comprising: (A) contacting a gas comprising oxygen, propane and propylene with at least one catalyst under reaction conditions sufficient to at least partially convert the propylene into a final product comprising acrylic acid; (B) feeding said final product to a separation column, in which the final product is split into a liquid stream, which is rich in acrylic acid, and a gaseous by-product stream comprising propane and propylene in a volume ratio of from 99.9:0.1 to 95:5; (C) contacting the gaseous by-product stream with oxygen in the presence of a catalyst under reaction conditions sufficient to at least partially convert propane to acrylic acid.

Method for preparing acrylic acid from propane and propylene

A process for producing unsaturated carboxylic acids or unsaturated nitriles by vapor phase oxidation reaction of their corresponding Cto Calkanes, Cto Calkenes, and mixtures thereof, as a hydrocarbon starting material, wherein the process performance is monitored and the path of gasses through catalyst beds is altered. Improved catalyst lifetimes may be achieved.

Process for the (AMM)oxidation of lower molecular weight alkanes and alkenes

The amount of propionic acid produced in the process of oxidizing propane to acrylic acid is reduced by using a reactor with a length/diameter ratio &#x3e;10 and/or maintaining the difference between the target reaction temperature and the peak temperature within the reactor to less than 20&#xb0; C.

Reactor and process for propane oxidation

A polymeric catalyst, and methods of using the catalyst, comprising at least one of a monosulfonated ion exchange resin, monosulfonated gel, and macroreticular resin having a particle size of less than 560 &#x3bc;m and metal impregnated within the resin, where the metal is palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and/or silver.

Multireaction bifunctional polymeric catalyst

A method for producing a mixture of ethylene and carbon monoxide by contacting ethane and an oxygen source with a catalyst comprising synthetic cryptomelane or octahedral molecular sieve. The method further comprises condensing the alkyl propionate with formaldehyde to produce an alkyl methacrylate.

Process for the oxidative dehydrogenation of ethane

An improved process for the production of unsaturated carboxylic acids and unsaturated nitrites from their corresponding Cto Calkanes, or mixtures of Cto Calkanes and alkenes, that involves a multi-stage reaction system which employs both separation of the oxidation product from one or more intermediate effluent streams, as well as feeding additional oxygen to reaction zones subsequent to the first reaction zone.

Process for the selective (amm)oxidation of lower molecular weight alkanes and alkenes

A mixed metal oxide, which may be an orthorhombic phase material, is regenerated, selectively enriched or selectively poisoned as a catalyst to reduce catalyst aging for the production of unsaturated carboxylic acids, or unsaturated nitrites, from alkanes, or mixtures of alkanes and alkenes, by contacting said mixed metal oxide with a an oxidizing gas such as oxygen, air, steam and combinations thereof is permitted to flow through the catalyst in a regenerator at a temperature of from 300&#xb0; C. to 600&#xb0; C. to form said regenerated catalyst.

Regeneration of mixed metal oxide catalysts

An improved process for producing an atmosphere suitable for carburizing steel components by adding a small amount of oxygen to a mixture of natural gas and carbon dioxide, pre-heating the mixture to the desired reaction temperature in the presence of an inert material or a non-nickel-based catalyst that promotes the reaction between oxygen and natural gas without forming coke to avoid catalyst deactivation by coke formation, and reacting natural gas with carbon dioxide at high temperature in the presence of a catalyst.

Process for producing carburizing atmospheres

A process for hydrocracking heavy, high aromatic content feeds, such as cycle oil, using a catalyst composition containing a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal.

Process for hydrocracking cycle oil

A process for hydrocracking heavy hydrocarbon feeds using a catalyst composition containing a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. The hydrocracking product has high isoparaffin to normal paraffin ratios and with minimal ethane and methane byproducts at high conversions. The hydrocracking step is useful in processes for producing high quality lubricating oil basestocks, along with naphtha and distillate products.

Process for selective wax hydrocracking

A process for hydrotreating a hydrocarbon feedstock, such as light cycle oil, using a catalyst composition containing a hydrogenation/dehydrogenation component and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. The hydrotreating process removes contaminants, such as sulfur and/or nitrogen, from the feedstock.

Process for hydrotreating

There is provided a process for converting methane to hydrocarbons having at least two carbon atoms. The process involves contacting methane with an oxidizing agent, such as oxygen, at a relatively moderate temperature of less than about 700.degree. C. and a relatively high pressure of greater than about 20 atmospheres.

Process for direct oxidative conversion of methane to higher

A mixture of organic compounds comprising a major amount of liquid hydrocarbons, mostly aromatic, is formed by the direct partial oxidation of methane in the presence of a ZSM-5 catalyst. The reaction conditions are substantially the same as those required for the direct homogeneous partial oxidation to methanol. However, liquid hydrocarbon formation depends on the presence of a small amount of an impurity such as propane or propylene in the feed; in the absence of such, only methanol is formed. With such modifier present, controls of reaction parameters, e.g., temperature, permits synthesis of both methanol and liquid hydrocarbons in desired proportions. Properly processed natural gas can serve to provide methane and at least part of the reaction modifier.
