摘要： The present invention discloses a method and a process of producing ammonia from methane extracted from methane-hydrate at the site of methane-hydrate extraction. The method and the process comprise coupled chemical reactions. During the first reaction, carbon dioxide reacts methane-hydrate to produce carbon-dioxide-hydrate and methane: carbon dioxide+methane-hydrate⇄carbon-dioxide-hydrate+methane (CO2+CH4-hydrate⇄CO2-hydrate+CH4). The produced methane is reacted with water to produced carbon dioxide and hydrogen via the second reaction: methane+water⇄carbon dioxide+hydrogen (CH4+2H2O⇄CO2+4H2). One embodiment of the second reaction is a combination of the methane steam reforming reaction (CH4+H2O⇄CO+3H2) and the water-gas shift reaction (CO+H2O⇄CO2+H2), both are widely known in the art. The carbon dioxide produced in the second reaction is recycled and used for the first reaction. The hydrogen produced in the second reaction is reacted with nitrogen produced from an air separation process that is known in the art to produce ammonia via the third reaction: nitrogen+hydrogen→ammonia (N2+3H2→2NH3). One embodiment of the third reaction is the well-known Haber-Bosch process. The current invention is related to co-locating the ammonia synthesis at the methane-hydrate extraction sites to minimize the cost of transporting both methane and carbon dioxide over long distances. The process and the associated method also have the advantage of on-site carbon sequestration. The ammonia product produced via the current invention is easily transportable in liquid form from the production sites to the end-use sites as a carbon-free liquid fuel, a fertilizer and a chemical feedstock.

摘要： A method for evaluating the thermal exposure of a selected metal component which has been exposed to changing temperature conditions is described. The voltage distribution on a surface of the metal component, or on a metallic layer which lies over the component, is first obtained. The voltage distribution usually results from a compositional change in the metal component. The voltage distribution is then compared to a thermal exposure-voltage model which expresses voltage distribution as a function of exposure time and exposure temperature for a reference standard corresponding to the metal component. In this manner, the thermal exposure of the selected component can be obtained. A related device for evaluating the thermal exposure of a selected metal component is also described.

摘要： A fuel cell system comprises a hydrogen storage system for storing and releasing hydrogen, a fuel cell in fluid communication with the hydrogen storage system for receiving released hydrogen from the hydrogen storage system and for electrochemically reacting the hydrogen with an oxidant to produce electricity and an anode exhaust. A catalytic combustor is in fluid communication with the fuel cell for receiving the anode exhaust and for catalytically reacting the anode exhaust to produce an offgas having an elevated temperature that is greater than the temperature of the anode exhaust. The heat from the offgas is used to release the hydrogen from the hydrogen storage system.
