10. The reactor of claim 9 , said center support being a series of link pieces connected together, said series comprising at least two link pieces.

11. A reactor comprising:

a series of monoliths stacked together, wherein each monolith in said series having a top end and a bottom end, and each monolith in said series comprises a plurality of fins in an annular arrangement wherein said fins define substantially vertical flow channels for receiving fluid flow through said reactor such that said fluid flows through said monolith from one of said top end or bottom end to the opposite of said top end or bottom end;

said each monolith having an outer annular surface forming an outer annular diameter and an inner annular surface forming an inner annular diameter, said inner annular surface defining a center section of said reactor;

a series of bladders stacked together adjacent said inner annular surface of said series of monoliths, said series of bladders forming a boundary between said series of monoliths and said center section of said reactor; and

an outer tube adjacent said outer annular surface of said monolith.

12. The reactor of claim 11 , said series of bladders comprising a top bladder, a middle bladder and a bottom bladder, wherein each bladder in said series of bladders comprises a cone portion extending inward towards said center section and away from said monolith.

13. The reactor of claim 12 , wherein at least one bladder in said series of bladders comprises a vent for permitting fluid flow through said boundary between said center section and said monolith.

14. The reactor of claim 12 , said each cone portion has a center opening for receiving a center support.

15. The reactor of claim 12 , wherein at least one bladder in said series comprises an expansion spring inside, wherein said expansion spring is in contact with said at least one bladder in said series of bladders.

16. A reactor for use in a fluid flow system comprising:

a monolith having a length measured from the top surface of said monolith to the bottom surface of said monolith;

said monolith comprising a plurality of fins in an annular arrangement wherein said fins define flow channels for receiving fluid flow through said reactor;

said monolith having an outer annular surface forming an outer annular diameter and an inner annular surface forming an inner annular diameter, said inner annular surface defining a center section of said reactor;

an inner tube adjacent said inner annular surface of said monolith;

a cone washer adjacent said inner tube, wherein said cone washer forms an elbow joint with said inner tube; and

said elbow joint being located at a position selected from the group consisting of: greater than 50 percent of said monolith length from said top surface of said monolith for a down flow system or greater than 60 percent of said monolith length from said bottom surface of said monolith for an up flow system.

17. The reactor of claim 16 , further comprising a center support extending longitudinally through said center section of said reactor, wherein said cone washer is attached to said center support.

18. The reactor of claim 16 , said center support being a link piece.

19. The reactor of claim 16 , further comprising a floating ring plate attached to the bottom of said center support.

20. A reactor comprising:

a monolith comprising a plurality of fins in an annular arrangement wherein said fins define flow channels for receiving fluid flow through said reactor, said monolith being expandable in a radial direction;

said monolith having an outer annular surface forming an outer annular diameter and an inner annular surface forming an inner annular diameter, said inner annular surface defining a center section of said reactor;

an expandable corrugated inner tube adjacent said inner annular surface of said monolith;

an expandable corrugated cone washer adjacent said inner tube, wherein said inner tube and said cone washer form a substantially leak proof boundary between said monolith and said center section of said reactor; and

said boundary forcing substantially all fluid flow through said reactor through said monolith and away from said center section of said reactor.

21. The reactor of claim 20 , further comprising a center support extending longitudinally through said center section of said reactor, wherein said center support is attached to said cone washer.
