摘要:
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.

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by the reactant mixture and is operative to convert a majority of the reactant mixture to hydrogen peroxide that is withdrawn via an egressing product stream.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.
摘要:
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.

摘要:
A microchannel polymerization reactor comprising: (a) a first microchannel adapted to carry a reactant stream; (b) a fluid conduit adapted to carry a fluid in thermal communication with the first microchannel; and (c) a static mixer in fluid communication with the first microchannel adapted to provide a mixing zone operative to change the cross-sectional fluid flow profile at a predetermined point along the first microchannel without changing the primary direction of the reactant stream through the first microchannel. The present invention also includes a method of carrying out a polymerization reaction within a microchannel reactor comprising: (i) directing at least one of monomer, initiator, water, surfactant, coagulant, and solvent into a reactant stream and into contact with reactant flowing within a first microchannel to initiate a polymerization reaction occurring within a first microchannel; and (ii) mixing the reactant of the reactant stream by positioning at least one static mixer in series with the reactant stream, where the static mixer is adapted to change a cross-sectional fluid flow profile of the reactant stream flowing through the first microchannel without changing a primary direction of the reactant stream through the first microchannel.
