Abstract: 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.

Abstract: Provided is a process and apparatus for exchanging heat energy between three or more streams in a millichannel apparatus, which millichannel apparatus may comprise a heat exchanger which may be integrated with a millichannel reactor to form an integrated millichannel processing unit. The combining of a plurality of integrated millichannel apparatus to provide the benefits of large-scale operation is enabled. In particular, the millichannel 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.

Abstract: 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.

Abstract: The invention provides apparatuses and techniques for controlling flow between a manifold and two or more connecting microchannels. Flow between plural connecting microchannels, that share a common manifold, can be made more uniform by the use of flow straighteners and distributors that equalize flow in connecting channels. Alternatively, flow can be made more uniform by sections of narrowed diameter within the channels. Methods of making apparatus and methods of conducting unit operations in connecting channels are also described.
