  • Publication number: 20070298486
    Abstract: 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.

  • Publication number: 20170327444
    Abstract: The present technology is directed to processes involving formation of hydrocarbons and oxygenated hydrocarbons through use of oxygen supplied by ion transport membranes. More particularly, the present technology relates in part to a process involving steam reforming and subsequent production of a synthetic product where carbon dioxide and/or hydrogen downstream of the process is reclaimed to generate the synthetic product. The present technology also relates in part to an ethylene formation process involving a viral-templated coupling catalyst in the presence of an ion transport membrane.

  • Patent number: 8802039
    Abstract: Novel designs for microchannel apparatus are described in which microchannels are shaped to reduce the amount of material needed to build an apparatus. In these designs, some microchannels are shaped, in cross-section, to provide relatively more structural material in areas of greatest stress, while leaving greater area for unit operations in areas of the apparatus that are subjected to relatively less stress.
