The invention provides methods, apparatus and systems in which there is partial boiling of a liquid in a mini-channel or microchannel. The partial boiling removes heat from an exothermic process.

Partial boiling in mini and micro-channels

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

Provided is a process and device for exchanging heat energy between three or more streams in a microchannel heat exchanger which can be integrated with a microchannel reactor to form an integrated microchannel processing unit. The combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation is enabled. In particular, the microchannel heat exchanger enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc.

Multi-stream microchannel device

An apparatus is described which comprises at least one process microchannel having a height, width and length, the height being up to about 10 mm, the process microchannel having a base wall extending in one direction along the width of the process microchannel and in another direction along the length of the process microchannel; at least one fin projecting into the process microchannel from the base wall and extending along at least part of the length of the process microchannel; and a catalyst or sorption medium supported by the fin.

Novel manifolds and methods of flow through manifolds are described. Apparatus and techniques are described in which flow from a relatively large volume header is equally distributed to process channels. Methods of making laminated, microchannel devices are also described.

Manifold designs, and flow control in multichannel microchannel devices

Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

The invention describes microchannel apparatus and catalysts that contain a layer of a metal aluminide or are made in a process in which a metal aluminide layer is formed as an intermediate. Certain processing conditions have surprisingly been found to result in superior coatings. The invention includes chemical processes conducted through apparatus described in the specification. Other catalysts and catalyst synthesis techniques are also described.

Interior microchannels within microchannel apparatus are uniformly coated. Remarkably, these uniform coatings are formed from materials that are applied to the interior microchannels after an apparatus has been assembled or manufactured. Coatings can be made uniform along the length of a microchannel, in the corner of a microchannel, and/or throughout numerous microchannels in an array of microchannels. Techniques for tailoring the application of washcoats onto microchannels is also described.

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

A process of conducting a catalyst reaction or fluid separation in comprising: at least one process microchannel having a height, width and length, the height being up to about 10 mm, the process microchannel having a base wall extending in one direction along the width of the process microchannel and in another direction along the length of the process microchannel; at least one fin projecting into the process microchannel from the base wall and extending along at least part of the length of the process microchannel; and a catalyst or sorption medium supported by the fin.

New designs, methods and processes are described that in which laminated devices and configured in a style named the 'ortho' style. To form a device in the ortho style, plates or sheets are machined to have apertures and then stacked together such that the apertures connect and fluid can flow through the device in a direction that is substantially parallel to the direction of sheet thickness. Various laminated devices and processes using them are also described. For example, devices in which non-rectangular microchannels conform around reaction chambers or other bodies that need to be heated or cooled, are described. Features that separate or trip boundary layer and enhance heat transfer are also described.

Methods of making devices by stacking sheets and processes of conducting unit operations using such devices

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.
