Section: claims

1. A reactor installation tool comprising:a movable assembly comprising an exterior post unit, an upper manifold and a reactor sleeve attachment means, wherein the upper manifold is attached to the exterior post unit, anda fixed assembly comprising a center post, a lower manifold andan expandable clamping unit having clamp shoes for pressing against an inner surface face of a hollow reactor tube for releasably securing the fixed assembly to the hollow reactor tube, wherein the lower manifold and expandable clamping unit are attached to the center post. 2. The reactor installation tool of claim 1, said lower manifold being a circular disc, said circular disc having through holes for receiving said exterior post unit. 3. The reactor installation tool of claim 2, said circular disc having a top surface and a bottom surface, said bottom surface having a center post attachment means extending outward. 4. The reactor installation tool of claim 3, said center post having a proximal end and a distal end, said proximal end being suitable for engaging said center post attachment means to secure said center post to said lower manifold. 5. The reactor installation tool of claim 4, said distal end of said center post being attached to a stationary end stop. 6. The reactor installation tool of claim 5, said stationary end stop being a plate. 7. The reactor installation tool of claim 5, said stationary end stop comprising an anvil and an anvil disc. 8. The reactor installation tool of claim 5, said stationary end stop being a circular plate having a diameter and a radial outer surface face, and said radial outer surface face having radial cogs for engaging a reactor sleeve. 9. The reactor installation tool of claim 2, said exterior post unit being slidable in said through holes of said lower manifold. 10. The reactor installation tool of claim 1, said exterior post unit having two or more posts. 11. The reactor installation tool of claim 10, said reactor sleeve attachment means comprising a centering spider plate attached to said two or more posts. 12. The reactor installation tool of claim 11, said centering spider plate being a circular disc having a diameter and a radial outer surface face, and said radial outer surface face having radial cogs for engaging a reactor sleeve. 13. The reactor installation tool of claim 12, said reactor sleeve having a diameter and a radial inner surface face that defines a hollow cylinder, said radial inner surface face having radial cogs. 14. The reactor installation tool of claim 13, said reactor sleeve attachment means further comprising a locking hub for engaging said radial cogs of said centering spider plate and said radial cogs of said reactor sleeve. 15. The reactor installation tool of claim 12, said diameter of said centering spider plate being less than said diameter of said reactor sleeve such that said centering spider plate is slidable in said hollow cylinder of said reactor sleeve. 16. The reactor installation tool of claim 10, said two or more posts being spaced equally around said center post. 17. The reactor installation tool of claim 1, said expandable clamping unit being an expandable jaw unit. 18. The reactor installation tool of claim 17, said expandable jaw unit comprising a mounting sleeve. 19. The reactor installation tool of claim 18, said clamp shoes being attached to said mounting sleeve. 20. The reactor installation tool of claim 19, said clamp shoes being movably attached to said mounting sleeve such that said clamp shoes can extend outward from said mounting sleeve. 21. The reactor installation tool of claim 20, said clamp shoes being movably attached to said mounting sleeve by a pneumatic cylinder. 22. The reactor installation tool of claim 19, said clamp shoes having at least two faces, one of said at least two faces having a radius for contacting the hollow reactor tube. 23. The reactor installation tool of claim 18, said mounting sleeve being an elongated body having a distal end and a proximal end, wherein said elongated body has a hollow through hole for receiving said center post, said through hole extending from said distal end to said proximal end. 24. The reactor installation tool of claim 1, said upper manifold being a circular disc, said circular disc having recesses for receiving said exterior post unit. 25. The reactor installation tool of claim 24, said circular disc having a diameter and a radial outer surface face, said outer surface face being attached to an upper manifold guard. 26. The reactor installation tool of claim 1, said upper manifold having a lifting means and a stop block.
