Appl. No.:

10/085436

Inventors:

James Kelly Kindig - Phoenix AZ
Boyd R. Davis - Kingston, CA

Thomas E. Weyand - New Brighton PA

Assignee:

Alchemix Corporation - Carefree AZ

International Classification:

C01B 308

US Classification:

481275, 48210, 423359, 423657, 423658

Abstract:

A method for the production of hydrogen gas. The hydrogen gas is formed by steam reduction using a metal/metal oxide couple to remove oxygen from water. Steam is contacted with a molten metal mixture including a first reactive metal such as iron dissolved in a diluent metal such as tin. The reactive metal oxidizes to a metal oxide, forming a hydrogen gas and the metal oxide can then be reduced back to the metal for further production of hydrogen without substantial movement of the metal or metal oxide to a second reactor.

US Classification:

48210, 252372, 252373, 252376, 423359, 518704

Abstract:

A method for the production of a hydrogen-containing gas composition, such as a synthesis gas including hydrogen and carbon monoxide. The molar ratio of hydrogen to carbon monoxide (H :CO) in the synthesis gas can be well-controlled to yield a ratio that is adequate for the synthesis of useful products such as methane or methanol, without the need to remove carbon oxides from the gas stream to adjust the ratio.

International Classification:

C10J 3/00
C10J 3/57

US Classification:

04819700A, 04819700R, 048210000, 048209000

Abstract:

A method for the gasification of a hydrocarbon feedstock that has a high moisture content to produce useful co-products such as high-value hydrocarbon fuels, pure H, electricity, and/or ammonia. The method advantageously gasifies the carbon in the feedstock to carbon monoxide (CO) without producing large quantities of carbon dioxide (CO). Supplemental hydrogen (H) is co-produced by reacting steam (HO) generated from the moisture in the hydrocarbon feedstock with a molten metal.

Abstract:

A method for the gasification of a hydrocarbon-bearing feedstock to produce useful co-products such as high-value hydrocarbon fuels, pure H, electricity, and/or ammonia. The method advantageously gasifies the carbon in the feedstock to carbon monoxide (CO) without producing large quantities of carbon dioxide (CO). Supplemental hydrogen (H) is also produced by reacting steam (HO) with a metal. The method can advantageously produce two separate syngas streams, one that is CO-rich and one that is H-rich.

International Classification:

C22B 100

US Classification:

75 1R

Abstract:

In a process for beneficiating one or more mineral values of sulfide ores by treating the sulfide ore with a metal containing compound under conditions such as to selectively enhance the magnetic susceptibility of the mineral values to the exclusion of the gangue in order to permit a separation between the values and gangue, the improvement comprising pretreating the sulfide ore by heating it to a temperature of at least about 80. degree. C. for at least about 0. 1 hours.

Abstract:

Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction. The fine fraction is deslimed in a countercurrent cyclone circuit and then separated as multiple fractions of different size specifications in dense medium cyclones. The dense medium contains ultra-fine magnetite particles of a narrow size distribution which aid separation and improves magnetite recovery. Magnetite is recovered from each separated fraction independently, with non-magnetic effluent water from one fraction diluting feed to a smaller-size fraction, and improving both overall coal and magnetite recovery. Magnetite recovery is in specially designed recovery units, based on particle size, with final separation in a rougher-cleaner-scavenger circuit of magnetic drum separators incorporating a high strength rare earth magnet.
