摘要:
Disclosed is a film-type getter for removing moisture, oxygen and hydrogen all together and a producing method thereof. The getter is used for an OELD device that is sealed within an enclosure to avoid failure caused by moisture, oxygen and hydrogen. The film-type getter is so flexible that it can be easily attached to the inside of OELD devices upon its use. The getter includes a moisture-getting component that reacts with moisture to generate hydrogen, an oxygen-getting component that reacts with oxygen to be changed into solid oxides, a hydrogen reactive substance that reacts with or absorbs hydrogen, a hydrogenation catalyst, and a polymer binder that binds the moisture-getting component, the oxygen-getting component, the hydrogen reactive substance and the hydrogenation catalyst to form a flexible film.

A mercury capture system and method that includes the equipment for and the production of a mercury-sorbent metal sulfide in a flue gas conduit of a coal fired power plant. The system can include transition metal salt solution injection and sulfur solution injection apparati that can introduce transition metal salt solution and sulfur solution droplets (individually or as a co-injection) into the flue gas stream. The method can include the introduction (individually or as a co-injection) of a copper salt, an iron salt, and a sulfur compound into the flue gas stream, wherein the mercury-sorbent metal sulfide can be manufactured and reacted with mercury in the flue gas.

Un dispositif de piégeage de gaz inflammables tels l'hydrogène comprend des moyens actifs (3) à l'intérieur d'une enveloppe (1) close sauf à des ouvertures obturées par des filtres (2) ne laissant normalement passer que les gaz à piéger. Le piégeage entretient une dépression à l'intérieur de l'enveloppe, qui aspire continuellement les gaz produits à l'extérieur. Le piège peut fonctionner sans aucun entretien et pendant de longues durées, y compris dans un milieu complètement clos.
摘要:
The present invention provides apparatus and methods for separating fluid components, for example, hydrogen. In preferred embodiments, the apparatus and methods utilize microchannel devices with small distances for heat and mass transfer to achieve rapid cycle times and surprisingly large volumes of fluid components separated in short times using relatively compact hardware.

An integrated fuel combustion system with adsorptive gas separation separates a portion of carbon dioxide from a combustion gas mixture and provides for recycle of separated carbon dioxide to the intake of the fuel combustor for combustion. A process for carbon dioxide separation and recycle includes: admitting combustion gas to an adsorptive gas separation system contactor containing adsorbent material; adsorbing a portion of carbon dioxide; recovering a first product gas depleted in carbon dioxide for release or use; desorbing carbon dioxide from the adsorbent material and recovering a desorbed second product gas enriched in carbon dioxide for sequestration or use; admitting a conditioning fluid into the contactor and desorbing a second portion of carbon dioxide to recover a carbon dioxide enriched conditioning stream; and recycling a portion of the carbon dioxide enriched conditioning stream to an inlet of fuel combustor to pass through the fuel combustor for combustion.

An air changeover system (100) for a metal hydride heat pump is disclosed. The system (100) includes metal hydride reactor modules (102, 104) aligned and separated by a partition (118); a shell containing the reactor modules (102, 104), the shell is compartmentalized to define separate insulated chambers for each of the reactor modules (102 & 104); and a bearing assembly (110) supporting the modules (102, 104) at a location about the partition (118), wherein the bearing assembly (110) rotates said modules (102, 104) about an axis during the absorption and the desorption mode. The system (100) reduces thermal inertia and pressure drop in the heat transfer medium while flowing through the heat pump, to enhance the performance and conserve energy.
摘要:
L'invention consiste en un procédé de fabrication de cendres à partir de la combustion du charbon, ce procédé comportant au moins une étape de mise en contact du charbon avec un agent absorbant d'une part, cet agent absorbant étant d'autre part contenu dans une phase aqueuse en présence d'un dispersant (méth)acrylique, préférentiellement d'un polymère peigne (méth)acrylique. On parvient ainsi à lutter efficacement contre les émissions de dioxyde de carbone, de même que contre les composés à base de soufre, d'azote ou de mercure qui résultent de la combustion du charbon.
摘要:
A metal hydride hydrogen storage unit utilizing compartmentalization to maintain a uniform metal hydride powder density thereby reducing stress on the vessel due to repeated cycling. An hydrogen storage alloy powder occupies at least 60% of the available interior volume of the hydrogen storage unit. Upon cycling of the hydrogen storage alloy powder between hydriding and dehydriding, the rate of increase in the average equivalent pressure exerted on the sidewall is less than 25 psi over at least 20 cycles, the hydriding portion of each of the cycles including the step of charging said hydrogen storage alloy powder to at least 60% of its maximum storage capacity.
