A flow reactor fluidic module (12) includes a reactant fluid module (20) having an internal process fluid passage (22) and a first major planar outer surface (24a) and a thermal resistance R between the internal process fluid passage (22) and the first major planar surface (24); a thermal control fluid module (30) having an internal thermal control fluid passage (32) and a second major planar outer surface (34a); a holding structure (50) holding the reactant fluid module (20) and the thermal control fluid module (30); and a gap (25) separating the first major planar surface (24a) from the second major planar surface (34a). The gap (25) comprises an interchangeable or replaceable substance or sheet (26) having a thermal resistance G across the gap (25), wherein G is not equal to R.
摘要:
The present invention relates to an automated radiosynthesis device adapted for enhanced automatic disconnection of a disposable kit once a radiosynthesis has been carried out. The automated radiosynthesis device of the invention therefore reduces the time to remove the disposable kit from the radiosynthesis device and reduces radiation exposure to the operator.

A preferred modular microplasma microchannel reactor device includes a microchannel array arranged with respect to electrodes for generation of plasma and isolated by dielectric from the electrodes. A cover covers a central portion of the microchannel array, while leaving end portions of the microchannel array exposed. A gas inlet and product outlet are arranged to permit flow into, through and out of the microchannel array. Reactor modules of the invention include pluralities of the modular reactor devices. The reactors devices can be arranged by a housing or a frame to be in fluid communication. A system of the invention arranges pluralities of modules. Preferred module housings, frames and reactors include structural features to create alignments and connections. Preferred modules include fans to circulate feedstock and reaction product. Other reactor devices provide plasma actuation for flow.
摘要:
A reactor includes a reaction-side flow passage (210) through which a reaction fluid being a fluid constituting a reaction object flows; a temperature controller (heat-medium side flow passage) (220) configured to heat or cool the reaction fluid from outside the reaction-side flow passage (210); and a catalyst (140) configured to promote a reaction of the reaction fluid, the catalyst provided in the reaction-side flow passage (210) so that a contact area with the reaction fluid is larger on a downstream side than on an upstream side in the reaction-side flow passage (210).
摘要:
The disclosed invention relates to a process for converting a reactant composition comprising H 2 and Co to a product comprising at least one aliphatic hydrocarbon having at least about 5 carbon atoms, the process comprising: flowing the reactant composition through a microchannel reactor in contact with a Fischer-Tropsch catalyst to convert the reactant composition to the product, the microchannel reactor comprising a plurality of process microchannels containing the catalyst; transferring heat from the process microchannels to a heat exchanger; and removing the product from the microchannel reactor; the process producing at least about 0.5 gram of aliphatic hydrocarbon having at least about 5 carbon atoms per gram of catalyst per hour; the selectivity to methane in the product being less than about 25%. The disclosed invention also relates to a supported catalyst comprising Co, and a microchannel reactor comprising at least one process microchannel and at least one adjacent heat exchange zone.
摘要:
Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RF) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.
