Abstract

Reactors are provided that can include a first set of fluid channels and a second set of fluid channels oriented in thermal contact with the first set of fluid channels. The reactor assemblies can also provide where the channels of either one or both of the first of the set of fluid channels are non-linear. Other implementations provide for at least one of the first set of fluid channels being in thermal contact with a plurality of other channels of the second set of fluid channels. Reactor assemblies are also provided that can include a first set of fluid channels defining at least one non-linear channel having a positive function, and a second set of fluid channels defining at least another non-linear channel having a negative function in relation to the positive function of the one non-linear channel of the first set of fluid channels. Processes for distributing energy across a reactor are provided. The processes can include transporting reactants via a first set of fluid channels to a second set of fluid channels, and thermally engaging at least one of the first set of fluid channels with at least two of the second set of fluid channels.

Claims (34)

1. A reactor comprising:

a first set of fluid channels;

a second set of fluid channels oriented in thermal contact with the first set of fluid channels;

wherein individual channels of the first set of fluid channels are in fluid communication with individual channels of the second set of fluid channels at a rim of the reactor; and

wherein the channels of either one of the first or second set of fluid channels are non-linear.

2. The reactor of claim 1 wherein the first set of channels define microchannels.

3. The reactor of claim 1 wherein the first set of channels define mesochannels.

4. The reactor of claim 1 wherein the first and second set of channels define microchannels.

5. The reactor of claim 1 wherein the first and second set of channels define mesochannels.

6. The reactor of claim 1 wherein both the first and second sets of fluid channels are non-linear.

7. The reactor of claim 1 further comprising a member separating the first set of fluid channels from the second set of fluid channels.

8. The reactor of claim 7 wherein the member is thermally conductive.

9. The reactor of claim 7 wherein the member defines a floor of one of the sets of fluid channels and a ceiling of the other of the sets of fluid channels, in at least one cross section.

10. A reactor comprising:

a first set of fluid channels;

a second set of fluid channels oriented in thermal contact with the first set of fluid channels; and

wherein the channels of either one of the first or second set of fluid channels are non-linear; and wherein individual channels of either the first or second set of channels includes a dividing member.

11. The reactor of claim 10 wherein the dividing member extends to form a pair of fluid passageways.

12. The reactor of claim 11 wherein individual channels of both the first and second sets of channels include a dividing member.

13. The reactor of claim 10 wherein the dividing member is an impermeable solid.

14. A reactor of comprising:

a first set of fluid channels;

a second set of fluid channels oriented in thermal contact with the first set of fluid channels;

wherein the channels of either one of the first or second set of fluid channels are non-linear; and

wherein the other of the first or second set of fluid channels is linear.

15. The reactor of claim 14 wherein the first set of channels define microchannels.

16. The reactor of claim 14 wherein the first set of channels define mesochannels.

17. A reactor comprising:

a first set of fluid channels;

a second set of fluid channels oriented in thermal contact with the first set of fluid channels;

wherein the channels of either one of the first or second set of fluid channels are non-linear; and

wherein the first set of fluid channels and the second set of fluid channels are configured such that a fluid reactant can traverse the first set of fluid channels and pass through a fluid passageway to the second set of fluid channels where the fluid can then traverse the second set of fluid channels and then exit the reactor.

18. The reactor of claim 17 wherein the first set of channels define microchannels.

19. The reactor of claim 17 wherein the first set of channels define mesochannels.
