Abstract

A micro-reactor system assembly comprises a stack of at least n process modules ( 1 - 6 ), wherein n is an integer equal to or greater than 1, made from a rigid first material and comprising at least one reactive fluid passage ( 1 A, 1 B, 2 A, 3 A, 6 A) for accommodating and guiding a reactive fluid, and at least n+1 heat exchange modules ( 7, 8 ) made from a ductile second material other than said first material and comprising at least one heat exchange fluid passage ( 7 A, 8 A) for accommodating and guiding a heat exchange fluid, wherein each process module ( 1 - 6 ) is sandwiched between two adjacent heat exchange modules ( 7, 8 ).

First claim

What is claimed is:

1. A micro-reactor system assembly, comprising a stack of:
at least n process modules, wherein n is an integer equal to or greater than 1, each process module being made from a first material and comprising at least one reactive fluid passage extending between at least one reactive fluid inlet port and at least one reactive fluid outlet port for accommodating and guiding a reactive fluid;
and at least n+1 heat exchange modules, each of said heat exchange modules being made from a second material other than said first material and comprising at least one heat exchange fluid passage extending between at least one heat exchange fluid inlet port and at least one heat exchange fluid outlet port for accommodating and guiding a heat exchange fluid,
wherein each process module is sandwiched between two adjacent heat exchange modules, and
wherein said second material is more ductile than said first material.

2. A micro-reactor system assembly according to claim 1 , wherein
said first material is resistant to corrosion and pressure and is selected from the group consisting of stainless steel, hastelloy, tungsten, tantalum, titanium, ceramics, graphite and/or a combination of one or more of said first materials; and
said second material is heat conducting and is selected from the group consisting of aluminum, aluminum alloys, copper, copper alloys, silver and silver alloys and/or a combination of one or more of said second materials.

3. A micro-reactor assembly according to claim 1 , wherein said second material deforms when pressed against said at least n process modules for providing a fluid-tight seal between each heat exchange module and each process module at a contacting surface of each heat exchange module adjacent each heat exchange fluid inlet port and each heat exchange fluid outlet port.

4. A micro-reactor assembly according to claim 3 , wherein said second material elastically deforms under pressure.

5. A micro-reactor assembly according to claim 3 , wherein said second material plastically deforms under pressure.

6. A micro-reactor system assembly according to claim 1 , wherein said at least n process modules comprise:
a mixing module, the at least one reactive fluid passage of which comprising a mixing portion for receiving and mixing at least two reactive fluids;
a thermal adjusting module disposed upstream of said mixing module for adjusting a temperature of said at least two reactive fluids prior to entering said mixing module; and
one or more retention modules disposed downstream of the mixing module for accommodating the reactive fluid mixture.

7. A micro-reactor system assembly according to claim 1 , wherein said at least one reactive fluid passage is a flat passage comprising curved and/or straight parts to enable a flow of the respective reactive fluid along a tortuous path, said flat passage having a width/height ratio in the range of 1:4 to 1:50.

8. A micro-reactor according to claim 1 , wherein said at least n process modules comprise at least two process modules.

9. A micro-reactor system assembly according to claim 1 , wherein said at least n+1 heat exchange modules comprise:
a first heat exchange module, the at least one heat exchange fluid inlet port of which communicates with a first heat exchange fluid reservoir;
a second heat exchange module, the at least one heat exchange fluid outlet port of which communicates with a second heat exchange fluid reservoir; and
at least one further heat exchange module disposed between said first heat exchange module and said second heat exchange module.

10. A micro-reactor system assembly according to claim 1 , wherein said at least n process modules and/or said at least n+1 heat exchange modules comprise each a first plate and a second plate permanently joined with one another by soldering, brazing, welding or gluing, and wherein each of said reactive fluid passages, heat exchange fluid passages, reactive fluid inlet ports and reactive fluid outlet ports, and/or heat exchange fluid inlet ports and heat exchange fluid outlet ports is provided between said first plate and said second plate.

11. A micro-reactor system assembly according to claim 10 , wherein each of said reactive fluid passages, heat exchange fluid passages, reactive fluid inlet ports and reactive fluid outlet ports, and/or heat exchange fluid inlet ports and heat exchange fluid outlet ports is formed by ablating an inner surface of at least one of said first plate and said second plate.

12. A micro-reactor system assembly according to claim 10 , wherein a structured intermediate plate is sandwiched between said first plate and said second plate of said at least n+1 heat exchange modules to provide said heat exchange fluid passages.

13. A micro-reactor system assembly according to claim 1 , further comprising a first frame means and a second frame means, wherein said at least n process modules and said at least n+1 heat exchange modules are pressed against each other by said first and second frame means.

14. A micro-reactor assembly according to claim 13 , further comprising at least two tie-rods disposed at a circumference of said micro-reactor system assembly between said first and second frame means for pressing said at least n process modules and said at least n+1 heat exchange modules together.

15. A micro-reactor system assembly comprising:
a first heat exchange module, said first heat exchange module having a heat exchange fluid inlet port, a heat exchange fluid outlet port and at least one heat exchange fluid passage extending between said heat exchange fluid inlet port and said heat exchange fluid outlet port for accommodating and guiding a heat exchange fluid;
a second heat exchange module connected in a stacked arrangement with said first heat exchange module, said second heat exchange module having a heat exchange fluid inlet port, a heat exchange fluid outlet port and at least one heat exchange fluid passage extending between said heat exchange fluid inlet port and said heat exchange fluid outlet port for accommodating and guiding a heat exchange fluid; and
a process module sandwiched between said first and second heat exchange modules, said process module having at least one reactive fluid passage extending between at least one reactive fluid inlet port and at least one reactive fluid outlet port for accommodating and guiding a reactive fluid,
wherein each of said first heat exchange module, said second heat exchange module and said process module comprises a first plate and a second plate permanently joined with one another, said first and second plates of said first and second heat exchange modules defining said heat exchange fluid passage therebetween, and said first and second plates of said process module defining said reactive fluid passage therebetween.

16. A micro-reactor system assembly according to claim 15 , wherein each of said fluid passage, said fluid inlet port and said fluid outlet port is formed by ablating an inner surface of at least one of said first plate and second plate.

17. A micro-reactor system assembly according to claim 15 , further comprising a structured intermediate plate sandwiched between said first plate and said second plate, said intermediate plate having said fluid passage formed therein.

18. A micro-reactor system assembly according to claim 15 , wherein said fluid passage comprises a flat passage including curved and/or straight parts to enable a flow of fluid along a tortuous path, said flat passage having a width/height ratio in the range of 1:4 to 1:50.
