This invention describes gas-solid, liquid-solid and gas-solid-liquid processes in microchannels devices including such processes as heterogeneous catalysis, particle formation, particle attrition, particle separation and adsorption or desorption of selected species. Various processes can be enhanced by the unique properties of microchannels such as the predominance of laminar flow, high rates of shear, high rates of heat transfer and high rates of mass transfer. Also encompassed by this invention are methods for the introduction to and removal from microchannels of particle containing fluid streams.
摘要:
This invention relates to a process for converting ethylene to ethylene oxide comprising: flowing reactants comprising ethylene and oxygen or a source of oxygen in a microchannel reactor in contact with a catalyst to form a product comprising ethylene oxide, the reactants undergoing an exothermic reaction in the microchannel reactor; and transferring heat from the microchannel reactor to a heat exchanger.
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:
Novel manifolds and methods of flow through manifolds are described. Apparatus and techniques are described in which flow from a relatively large volume header is equally distributed to process channels. Methods of making laminated, microchannel devices are also described.
摘要:
The disclosed invention relates to a process for treating or making an emulsion in a microchannel. The emulsion comprises a first liquid and a second liquid, the first liquid forming a continuous phase, the second liquid forming droplets dispersed in the continuous phase.
摘要:
The disclosed invention relates to a process for conducting an equilibrium limited chemical reaction in a microchannel reactor. The process involves the use of active heat exchange and is suitable for conducting exothermic and endothermic reactions. The process is particularly suitable for synthesizing methanol and dimethyl ether.
摘要:
This invention relates to a process for converting a hydrocarbon reactant to a product comprising an oxygenate or a nitrile, the process comprising: (A) flowing a reactant composition comprising the hydrocarbon reactant, and oxygen or a source of oxygen, and optionally ammonia, through a microchannel reactor in contact with a catalyst to convert the hydrocarbon reactant to the product, the hydrocarbon reactant undergoing an exothermic reaction in the microchannel reactor; (B) transferring heat from the microchannel reactor to a heat exchanger during step (A); and (C) quenching the product from step (A).
摘要:
The disclosed invention relates to a novel cobalt catalyst and to a process for converting a reactant composition comprising H2 and CO to a product comprising at least one aliphatic hydrocarbon having at least about 5 carbon atoms in a reactor using the catalyst. The process can be conducted in any reactor and is particularly suitable for microchannel reactors.
