A method of safely mixing a hydrocarbon with an oxidant is provided. The hydrocarbon and oxidant are saturated with a non-flammable liquid in pre-mix zones that are flooded with the non-flammable liquid and fluidly connected to a common mixing zone that is partially flooded with the non-flammable liquid. The saturated hydrocarbon and oxidant combine within the common mixing zone forming bubbles of a homogeneous gas mixture of hydrocarbon and oxidant, preferably in a ratio of hydrocarbon to oxidant that is outside of the flammability limit, that can exit the non-flammable liquid into a headspace where it can be retrieved for use in an oxidative reaction process such as oxidative dehydrogenation.

Inherently safe oxygen/hydrocarbon gas mixer

A catalyst, useful for oxidative dehydrogenation of ethane, comprising molybdenum, vanadium, tellurium, tantalum, and oxygen, prepared using a stage hydrothermal synthesis procedure, is provided. The catalyst comprises from 30 to 50 wt. % amorphous content and may be combined with a support/carrier material to form a catalyst material. The described catalysts and catalyst materials demonstrate high selectivity for ethylene at higher temperatures, show little to no decline in conversion and selectivity over time, and do not appear to be sensitive to low residual oxygen concentrations.

Mixed metal oxide catalyst containing tantalum for ODH of ethane

A system and method for converting carbon dioxide into products by contacting the carbon dioxide with catalyst in the presence of hydrogen in a reactor.

Catalytic conversion of carbon dioxide

The present disclosure relates to limiting the production of acetic acid in an oxidative dehydrogenation process to convert ethane to ethylene. The process of oxidative dehydrogenation includes feeding acetic acid, along with ethane and oxygen into an oxidative dehydrogenation reactor where contact with a catalyst leads to conversion of the ethane into ethylene and acetic acid. By including acetic acid in the feed, the amount of acetic acid produced may be limited and the ratio of ethylene produced to ethane consumed may increase.

Limiting acetic acid production in ethane ODH process

A method of converting one or more alkanes to one or more alkenes that includes providing a first stream containing one or more alkanes and oxygen to an oxidative dehydrogenation reactor; converting at least a portion of the one or more alkanes to one or more alkenes in the oxidative dehydrogenation reactor to provide a second stream exiting the oxidative dehydrogenation reactor containing one or more alkanes, one or more alkenes, and one or more of oxygen, carbon monoxide and acetylene; and providing the second stream to a second reactor containing a catalyst that includes CuO and ZnO and reacting the second stream to provide a third stream exiting the second reactor containing one or more alkanes, one or more alkenes, and lower or undetectable levels of oxygen and acetylene compared to the second stream.

Removal of carbon monoxide, oxygen and acetylene from an oxidative dehydrogenation process

A system for mitigating naturally occurring radioactive materials (NORM) in an oxidative dehydrogenation process includes a feed stream, an oxidative dehydrogenation (ODH) reactor, an effluent stream, a processing unit, and a NORM reduction unit. The feed stream includes oxygen, a hydrocarbon, and NORM. The ODH reactor is configured to receive the feed stream and react the hydrocarbon with the oxygen to form a dehydrogenated hydrocarbon and water. The effluent stream includes the dehydrogenated hydrocarbon, water, unreacted hydrocarbon, and NORM. The processing unit is configured to process the effluent stream to form a product stream and a recycle stream. The product stream includes the dehydrogenated hydrocarbon. The recycle stream includes unreacted hydrocarbon and NORM. The NORM reduction unit is configured to reduce an amount of the NORM in the recycle stream to produce a NORM-reduced recycle stream. The ODH reactor is configured to receive the NORM-reduced recycle stream.

Mitigating naturally occurring radioactive material in oxidative dehydrogenation

Mixed metal oxide catalysts having an amorphous content of not less than 40 wt. % are prepared by calcining the catalyst precursor fully or partially enclosed by a porous material having a melting temperature greater than 600° C. in an inert container including heating the catalyst precursor at a rate from 0.5 to 10° C. per minute from room temperature to a temperature from 370° C. to 540° C. under a stream of pre heated gas chosen from steam and inert gas and mixtures thereof at a pressure of greater than or equal to 1 psig having a temperature from 300° C. to 540° C. and holding the catalyst precursor at that temperature for at least 2 hours and cooling the catalyst precursor to room temperature.

Calcination process to produce enhanced ODH catalyst

This disclosure relates to a process of converting one or more alkanes to one or more alkenes that includes providing a first stream containing one or more alkanes and oxygen to an oxidative dehydrogenation process which converts at least a portion of the one or more alkanes to one or more alkenes in an oxidative dehydrogenation reactor, a second stream exiting the oxidative dehydrogenation process comprising one or more alkanes, and one or more alkenes; and providing at least a portion of the alkanes in the second stream to a catalytic membrane dehydrogenation process containing a catalyst loaded into a catalytic dehydrogenation membrane reactor which converts at least a portion of the alkanes to the corresponding alkenes and hydrogen.

Integration of oxidative dehydrogenation process with catalytic membrane dehydrogenation reactor process

The product distribution from an oxidative dehydrogenation process can be altered by co-feeding different ratios of ethanol to steam, in the range of 0.01 to 0.50 ethanol:steam to an oxidative dehydrogenation reactor. Increasing the ethanol to steam ratio was found to: increase ethylene yield; decrease acetic acid yield; increase, or decrease, or cause no effect on CO or COyield; and have negligible effect on ethane conversion. The feed ethanol is converted to carbonaceous products without negatively effecting the catalyst activity.

Oxidative dehydrogenation process

This document relates to oxidative dehydrogenation catalyst materials that include molybdenum, vanadium, beryllium, oxygen, and optionally aluminum.

Molybdenum-vanadium-beryllium-based oxidative dehydrogenation catalyst materials

A process, a system, and an apparatus for separation of an oxygenate from a stream is provided. More specifically, a stream comprising the oxygenate is introduced to a quench tower along with a caustic outlet stream comprising a metal salt. Contact between the oxygenate and the metal salt results in conversion of a portion of the oxygenate into a derivative salt. The derivative salt and unconverted oxygenate are condensed by quenching and substantially removed from the quench tower as an oxygenate outlet stream. The gaseous components of the stream, minus a substantial portion of the oxygenate, are removed from the quench tower as a quench outlet stream.

Oxygenate separation using a metal salt

The oxidative dehydrogenation of ethane comprises contacting a mixture of ethane and oxygen in an ODH reactor with an ODH catalyst under conditions that promote oxidation of ethane into ethylene. Conditions within the reactor are controlled by the operator and include, but are not limited to, parameters such as 5 temperature, pressure, and flow rate. Conditions will vary and can be optimized for a specific catalyst, or whether an inert diluent is used in the mixing of the reactants. Disclosed herein is a catalyst consisting of: MoWVTeFeNbOwhere X is determined by the valance of the metals.
