This invention relates to a process for conducting a hydrocracking or a hydrotreating process in a microchannel reactor. This invention also relates to a process and apparatus for flowing a vapor and liquid into a plurality of microchannels in a microchannel processing unit.

Process and apparatus employing microchannel process technology

This invention relates to a process and an apparatus for conducting simultaneous endothermic and exothermic reactions in a microchannel reactor. A start-up procedure for the microchannel reactor is disclosed.

Process and apparatus for conducting simultaneous endothermic and exothermic reactions

The disclosed invention relates to a process, comprising: flowing a first reactant feed stream comprising a reactant substrate and a second reactant feed stream comprising an alkylating agent, an acylating agent or a mixture thereof, in a process microchannel in contact with each other to form a product comprising at least one alkylation product, at least one acylation product, or a mixture thereof; transferring heat from the process microchannel to a heat sink; and removing the product from the process microchannel.

Process using microchannel technology for conducting alkylation or acylation reaction

This invention relates to a process for converting a hydrocarbon reactant to a product comprising an oxygenate or a nitrile, the process comprising: (A) flowing a reactant composition comprising the hydrocarbon reactant, and oxygen or a source of oxygen, and optionally ammonia, through a microchannel reactor in contact with a catalyst to convert the hydrocarbon reactant to the product, the hydrocarbon reactant undergoing an exothermic reaction in the microchannel reactor; (B) transferring heat from the microchannel reactor to a heat exchanger during step (A); and (C) quenching the product from step (A).

Process for converting a hydrocarbon to an oxygenate or a nitrile

The disclosed technology relates to an apparatus, comprising: at least one microchannel, the microchannel comprising at least one heat transfer wall; a porous thermally conductive support in the microchannel in contact with the heat transfer wall; a catalyst or a sorption medium supported by the porous support; and a heat source and/or heat sink in thermal contact with the heat transfer wall.

Support for use in microchannel processing

The disclosed invention relates to a process for conducting an equilibrium limited chemical reaction in a microchannel reactor. The process involves the use of active heat exchange and is suitable for conducting exothermic and endothermic reactions. The process is particularly suitable for synthesizing methanol and dimethyl ether.

Process for conducting an equilibrium limited chemical reaction using microchannel technology

The disclosed invention relates to a process for conducting a multiphase reaction in a microchannel. The process comprises: forming a multiphase reaction mixture comprising a first reactant and a second reactant; the first reactant comprising at least one liquid; the second reactant comprising at least one gas, at least one liquid, or a combination of at least one gas and at least one liquid; the first reactant forming a continuous phase in the multiphase reaction mixture; the second reactant forming gas bubbles and/or liquid droplets dispersed in the continuous phase; and reacting the first reactant with the second reactant in a process microchannel in the presence of at least one catalyst to form at least one product.

Multiphase reaction process using microchannel technology

The present invention includes methods and apparatuses for producing hydrogen peroxide using microchannel technology. An exemplary process for producing hydrogen peroxide comprises flowing feed streams into intimate fluid communication with one another within a process microchannel to form a reactant mixture stream comprising a hydrogen source and an oxygen source such as, without limitation, hydrogen gas and oxygen gas. Thereafter, a catalyst is contacted by the reactant mixture and is operative to convert a majority of the reactant mixture to hydrogen peroxide that is withdrawn via an egressing product stream. During the hydrogen peroxide chemical reaction, exothermic energy is generated and absorbed by the fluid within the microchannel as well as the microchannel itself.

Hydrogen peroxide production in microchannel reactors

The disclosed technology relates to a process for conducting a chemical reaction between at least one liquid reactant and at least one gaseous reactant in a process microchannel containing at least one catalyst, the catalyst comprising a solid phase catalyst or a homogeneous catalyst immobilized on a solid. In one embodiment, the process microchannel comprises a processing zone containing one or more structures for disrupting fluid flow and a reaction zone containing one or more structures for contacting and/or supporting the catalyst, the one or more structures for contacting and/or supporting the catalyst containing openings to permit the reactants to flow through the one or more structures and contact the catalyst.

Catalytic reaction process using microchannel technology

The disclosed invention relates to a process for converting ethylbenzene to styrene, comprising: flowing a feed composition comprising ethylbenzene in at least one process microchannel in contact with at least one catalyst to dehydrogenate the ethylbenzene and form a product comprising styrene; exchanging heat between the process microchannel and at least one heat exchange channel in thermal contact with the process microchannel; and removing product from the process microchannel. Also disclosed is an apparatus comprising a process microchannel, a heat exchange channel, and a heat transfer wall positioned between the process microchannel and heat exchange channel wherein the heat transfer wall comprises a thermal resistance layer.

Process for making styrene using mircochannel process technology

The disclosed invention relates to a process for making a multiphase mixture, comprising: flowing a first fluid stream through a process microchannel, the first fluid stream comprising at least one liquid and/or at least one gas, the process microchannel having an apertured section; flowing a second fluid stream through the apertured section into the process microchannel in contact with the first fluid stream to form the multiphase mixture, the second fluid stream comprising at least one gas and/or at least one microbody-forming material, the first fluid stream forming a continuous phase in the multiphase mixture, the second fluid stream forming a discontinuous phase dispersed in the continuous phase.

Multiphase mixing process using microchannel process technology

The present invention includes methods and apparatuses that utilize microchannel technology and, more specifically in exemplary form, producing hydrogen peroxide using microchannel technology. An exemplary process for producing hydrogen peroxide comprises flowing feed streams into intimate fluid communication with one another within a process microchannel to form a reactant mixture stream comprising a hydrogen source and an oxygen source such as, without limitation, hydrogen gas and oxygen gas. Thereafter, a catalyst is contacted by the reactant mixture and is operative to convert a majority of the reactant mixture to hydrogen peroxide that is withdrawn via an egressing product stream. During the hydrogen peroxide chemical reaction, exothermic energy is generated. This exothermic energy is absorbed by the fluid within the microchannel as well as the microchannel itself. In a preferred embodiment, a heat exchange fluid is in thermal communication with the microchannel housing the exothermic reaction and is operative to absorb a portion of this exothermic energy and transfer such energy from the microchannel.
