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. Superior results were achieved for combustion chambers which contained a gap for free flow through the chamber. 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.

Integrated reactors, methods of making same, and methods of conducting simultaneous exothermic and endothermic reactions

Novel methods of making laminated, microchannel devices are described. Examples include: assembly from thin strips rather than sheets; and hot isostatic pressing (HIPing) to form devices with a hermetically sealed wall. Laminated microchannel articles having novel features are also described. The invention includes processes conducted using any of the articles described.

Integrated combustion reactors and methods of conducting simultaneous endothermic and exothermic reactions

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 dehydrogenating hydrocarbons to yield unsaturated compounds are described. Reactor configurations useful for dehydrogenation are also described. Hydrocarbons can be dehydrogenated, for relatively long periods of time-on-stream, in a reaction chamber having a dimension of 2 mm or less to produce Hand an olefin. Techniques have been developed that reduce coke and allow stable, relatively long-term operation in small reactors.

Dehydrogenation reactions in narrow reaction chambers and integrated reactors

The present invention is a chemical reactor and method for catalytic chemical reactions having gas phase reactants. The chemical reactor has reactor microchannels for flow of at least one reactant and at least one product, and a catalyst material wherein the at least one reactant contacts the catalyst material and reacts to form the at least one product. The improvement, according to the present invention is: the catalyst material is on a porous material having a porosity that resists bulk flow therethrough and permits molecular diffusion therein. The porous material further has a length, a width and a thickness, the porous material defining at least a portion of one wall of a bulk flow path through which the at least one reactant passes.
