Filed:

Dec 13, 2000

Appl. No.:

09/736515

Inventors:

Oren V. Peterson - Pleasant Grove UT 84062

International Classification:

C21D 106

US Classification:

266252, 432127

Abstract:

A steel reheat furnace and method of use thereof are disclosed. The furnace includes a housing defining an interior furnace space that is substantially sealed from the environment. A carbon monoxide atmosphere is placed in the interior furnace space for enveloping the steel and protecting it from oxidation. Oxidation of the carbon monoxide generates heat that reheats the steel for later rolling into rolled steel. Flue gases are removed from the furnace by a furnace hood and flue system. The steel advances through the furnace by a roller system driven by frictional force.

Abstract:

A process and apparatus for generating hydrogen from oil shale. Crushed oil shale may be placed in a chamber and combusted with carbon monoxide, oxygen and steam to form a gas stream of hydrogen and carbon monoxide. The hydrogen and carbon monoxide stream may be passed through a mechanism to produce hydrogen. In one embodiment, the hydrogen and carbon monoxide stream may be passed through a catalytic converter to produce hydrogen and carbon dioxide. The hydrogen and carbon dioxide may be cooled further and passed through a scrubber to remove the carbon dioxide such that hydrogen is produced. In another embodiment, the hydrogen and carbon monoxide may be passed through fluidized beds of magnetite to produce metallic iron, carbon dioxide and water. The metallic iron may then be conveyed to another chamber, where it may be treated with steam, producing magnetite and hydrogen.

Abstract:

A process for producing liquid steel is disclosed. Carbon monoxide and oxygen may be combusted in a high temperature reactor. Iron and iron oxide materials, along with scrap steel if desired, may be placed in the high temperature reactor. Carbon dioxide produced in the high temperature reactor may be circulated through a back reactor vessel. Coke masses may be placed in the back reactor vessel. The coke may be formed by circulating heated carbon monoxide counter current to crushed coal in a rotary kiln. The carbon dioxide circulated through the back reactor vessel reacts with the coke to form carbon monoxide. The carbon monoxide may be conveyed to the high temperature reactor to be combusted with oxygen to produce the heat for forming the liquid steel.

Abstract:

A method and apparatus for preparing and delivering various types of carbon and microalloy steel, free of oxygen with abundance of nuclei, when cast producing ultra fine grain steel free of internal defeats with excellent quality. A horizontal sealed table caster has a chamber, containing a suitable atmosphere for casting, with a tube connecting to a tundish so as to allow a liquid to flow into the chamber. The liquid metal is captured on a cooling belt along the bottom of the chamber and is maintained as a specific width and depth. The cooling belt serves as a heat sink causing the liquid metal to solidify from the bottom up, allowing inclusions to migrate to the surface of the steel. A layer of liquid metal is maintained on top of the solidifying steel until the solidification reaches the surface. The belt moves the solid metal toward the exit of the chamber. As the liquid metal solidifies, the impurities migrate in the liquid metal, reaching the surface and a solid metal body free of inclusions with the superior properties is produced.

Abstract:

A process and apparatus for extracting oil from oil shale. Crushed oil shale is transported into a combustion chamber, along with relatively pure oxygen and carbon monoxide which are combusted to heat the oil shale sufficiently to release petroleum hydrocarbons, leaving a retorted oil shale containing a carbon residue. The combustion phase combines with the carbon residue to generate a recurring combustion/reaction cycle in which the carbon monoxide and oxygen are combusted to form carbon dioxide while retorting the oil shale by heat, and the carbon dioxide reacts with the carbon residue in the retorted oil shale to regenerate a carbon monoxide by-product. The petroleum hydrocarbons are cooled and processed into useable oils. The carbon monoxide by-product can be re-routed back to the combustion area of the combustion chamber and reused, or used in some separate application. Heat from the released petroleum and carbon monoxide by-product can be transferred back to the combustion chamber and also reused.
