Scalable reactor for microwave- and ultrasound- assisted chemistry

摘要

A reaction vessel for reacting liquid reagents comprises a metallic vessel 1 fed by reagent inlet and outlet pipes 3, 4. Multiple multi-layer metallic wires 5 forming a multi-wire coaxial waveguide extend through the vessel 1 between sealed and shaped dielectric caps 6 at either end of the vessel. The sealed caps include dielectric waveguides 7 having central conductors 8 connecting the wires 5 to single wire waveguides 9 outside the volume. A microwave generator 10 and resistive load 11 for absorbing excessive microwave power are attached to a respective waveguide 9. The vessel 1 is surrounded by a piezoceramic layer 12 driven by a generator 13 to provide ultrasonic mixing or stirring of the reagents. The vessel may further be surrounded by a vacuum layer 14 and plastic layer 15 to improve thermal insulation. The wires and/or vessel interior walls may be covered with resistive and/or catalytic layers (see figures 1c and 1d).
