摘要:
A chemical substance concentrator includes a channel allowing a sample containing a chemical substance to flow in a flowing direction in the channel, and a cell wall partitioning the channel into adsorption cells. Each of adsorption cells includes first and second electrodes disposed on the cell wall apart from each other and an adsorption device that adsorbs the chemical substance. The adsorption device contains metal oxide. The absorption device is disposed at a position contacting the first electrode and the second electrode such that the first and second electrodes are electrically connected via the adsorption device.

A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm ∼ 1.8 mm, and so that a thickness of a wall between the cell passages is within a range of 0.45 mm ∼ 0.60 mm. With this configuration, the honeycomb adsorbent exhibits BWC (Butane Working Capacity) of 6.5 g/dL or greater. By mixing fibrous meltable core melting away during baking, the honeycomb adsorbent has macropores configured to have a volume of 0.15 mL/g ∼ 0.35 mL/g with respect to an overall weight of the honeycomb adsorbent and metal oxide particles having a proportion of weight of 150 ∼ 250 % with respect to the activated carbon.

To reduce the emission of carbon dioxide and improve the energy efficiency in a hydrogen supply system. The hydrogen supply system (1) comprises: a reformer (5) for performing steam reforming of a hydrocarbon; a shift reaction unit (6) for producing a gas containing hydrogen and carbon dioxide by causing a water gas shift reaction of a gas obtained from the reformer; a first absorber (36) for absorbing the carbon dioxide contained in the gas obtained from the shift reaction unit in an absorption liquid; a hydrogenation reaction unit (8) for producing a hydrogenated aromatic compound by causing a hydrogenation reaction of an aromatic compound with a gas that has passed through the first absorber; and a regenerator (37) for separating the carbon dioxide from the absorption liquid by re-circulating the absorption liquid from the first absorber and heating the absorption liquid with heat generated from the hydrogenation reaction.

Die Erfindung richtet sich auf die Herstellung von nano-partikulärem Titandioxid in Agglomeratform aus einer hydrolysierten sauren Titanylverbindung, welche mit Alkalisilikat oder Alkalialuminat neutralisiert und anschließend thermisch behandelt wird. Das Produkt enthält kristallines Titandioxid mit Anatasstruktur und Siliciumoxid und/oder Aluminiumoxid und weist eine spezifische Oberfläche (BET) von etwa 200 bis 400 m 2 /g auf. Es findet Verwendung als Photokatalysator, Prozesskatalysator oder Adsorptionsmittel insbesondere bei der Reinigung von wässrigen Systemen.
摘要:
A system for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel is provided. The system includes a calcination chamber and a sealing-purger (90). The calcination chamber is configured to receive a plurality of loaded sorbent particles and a plurality of heat-transferring particles such that the loaded sorbent particles are heated within the calcination chamber so as to release carbon dioxide. The sealing-purger (90) includes at least one gravity driven moving particle bed (106). The at least one gravity driven moving particle bed (106) allows the plurality of heat-transferring particles or the plurality of sorbent particles to enter or leave the calcination chamber while restricting the flue gas from entering the calcination chamber and the released carbon dioxide from leaving the calcination chamber.
摘要:
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.
摘要:
A method for depositing a magnesium oxide thin film on a substrate by a laser abrasion method using a sintered body or single crystal of magnesium oxide as a target. In this method, a flat processed film made of magnesium oxide having a (111) plane as its front surface is prepared, using a substrate made of strontium titanate having a (111) plane as its principal surface or yttria-stabilized zirconia having a (111) plane as its principal surface, by directly depositing a film on the principal surface of the substrate and epitaxially growing the film.
