Patent ID: 7749456

Claim:
A heat-dissipation reactor having dimensions suitable for the manufacture of hollow carbon microballoons from phenolic microballoon precursors, which reactor comprises a walled reaction chamber having a bottom and no top, wherein the walls and bottom of said reaction chamber are made of steel or another iron alloy, said walls ranging from 24 to 40 inches in length, from 15 to 25 inches in width, and from 10 to 20 inches in depth in order to accommodate said phenolic microballoon precursors, said reaction chamber containing structural elements composed of highly thermally conductive aluminum material in the form of a vertical grid of aluminum plates, wherein said structural elements are arranged so that no point of volume within the walls of said reaction chamber is further than about 5 inches from one of said structural elements and wherein top edges of said highly thermally conductive structural element materials communicate with atmosphere above said reaction chamber.
