Abstract

A microreactor may include a reaction channel having at least one curved microchannel, the at least one curved microchannel having an outer and inner curved surfaces and being configured to generate a centrifugal force, an inlet configured to supply at least one reactant into the reaction channel, and an outlet bifurcated into a first sub-outlet in communication with the inner curved surface of the at least one curved microchannel and a second sub-outlet in communication with the outer curved surface of the at least one curved microchannel.

Claims (30)

1. A microreactor comprising:

a substantially circular reaction microchannel having an outer and inner curved surfaces and being configured to generate a centrifugal force;

an inlet configured to supply at least one solid catalyst particle and at least one reactant into the substantially circular reaction microchannel, wherein the inlet is tangentially connected to the outer curved surface of the substantially circular reaction microchannel; and

an outlet in communication with the inner curved surface of the substantially circular reaction microchannel.

2. The microreactor of claim 1 , wherein the outlet is protruded from the inner curved surface of the substantially circular reaction microchannel.

3. The microreactor of claim 1 , wherein the at least one reactant has any one of a gas phase, a liquid phase and a gas-liquid mixed phase.

4. The microreactor of claim 3 , wherein the substantially circular reaction microchannel is configured to flow the at least one solid catalyst particle along the outer curved surface thereof and to flow the at least one reactant along the inner curved surface thereof.

5. The microreactor of claim 1 , wherein the outlet is protruded from the inner curved surface of the substantially circular reaction microchannel at a position distanced away from the inlet such that the at least one reactant is substantially transformed into a product by contact with the at least one solid catalyst particle in the microchannel.

6. The microreactor of claim 1 , further comprising:

a filtering device configured to prevent the at least one solid catalyst particle from flowing into the outlet.

7. The microreactor of claim 6 , wherein the filtering device is a meshed filter or a baffle.

8. The microreactor of claim 1 , wherein the substantially circular reaction microchannel is configured to circulate the at least one solid catalyst particle along the outer curved surface thereof.

9. The microreactor of claim 6 , wherein the filtering device is positioned at a junction area between the outlet and the inner curved surface.

10. The microreactor of claim 1 , wherein the outlet is protruded toward the center of the microreactor.

11. The microreactor of claim 6 , wherein the filtering device is a baffle.

12. A microreactor system comprising:

a substantially circular reaction microchannel having an outer and inner curved surfaces and being configured to generate a centrifugal force;

an inlet configured to supply at least one solid catalyst particle and at least one reactant into the substantially circular reaction microchannel, wherein the inlet is tangentially connected to the outer curved surface of the substantially circular reaction microchannel;

an outlet in communication with the inner curved surface of the substantially circular reaction microchannel; and

a reservoir in communication with the outlet and configured to receive the at least one reactant or a product produced by the solid catalyst particle and the reactant,

wherein the substantially circular reaction microchannel is configured to flow the at least one solid catalyst particle along the outer curved surface thereof and to flow the at least one reactant along the inner curved surface thereof.

13. The microreactor system of claim 12 , wherein the outlet is protruded from the inner curved surface of the substantially circular reaction microchannel.

14. The microreactor system of claim 12 , wherein the at least one reactant has any one of a gas phase, a liquid phase and a gas-liquid mixed phase.

15. The microreactor system of claim 12 , wherein the outlet is protruded from the inner curved surface of the substantially circular reaction microchannel at a position distanced away from the inlet such that the at least one reactant is substantially transformed into a product by contact with the at least one solid catalyst particle in the microchannel.

16. The microreactor system of claim 12 , further comprising:

a filtering device configured to prevent the at least one solid catalyst particle from flowing into the outlet.

17. The microreactor system of claim 16 , wherein the filtering device is a meshed filter.

18. The microreactor system of claim 16 , wherein the filtering device is a baffle.

19. The microreactor system of claim 16 , wherein the filtering device is positioned at a junction area between the outlet and the inner curved surface.

20. The microreactor system of claim 12 , wherein the outlet is protruded toward the center of the microreactor.
