An integrated microchannel reactor and heat exchanger comprising: (a) a waveform sandwiched between opposing shim sheets and mounted to the shim sheets to form a series of microchannels, where each microchannel includes a pair of substantially straight side walls, and a top wall formed by at least one of the opposing shim sheets, and (b) a first set of microchannels in thermal communication with the waveform, where the waveform has an aspect ratio greater than two.


The invention describes features that can be used to control flow to an array of microchannels. The invention also describes methods in which a process stream is distributed to plural microchannels.


The invention described herein concerns microchannel apparatus that contains, within the same device, at least one manifold and multiple connecting microchannels that connect with the manifold. For superior heat or mass flux in the device, the volume of the connecting microchannels should exceed the volume of manifold or manifolds. Methods of conducting unit operations in microchannel devices having simultaneous disrupted and non-disrupted flow through microchannels is also described.
