| 20100041547 | METHOD FOR PRODUCTION OF CATALYST AND CATALYST PRODUCED BY THE METHOD - A method for producing a catalyst of the present invention is characterized by sequentially performing the steps of: (i) dipping an end face portion of a carrier structure having a catalytic component carried thereon in an aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; (ii) drying the dipped end face portion; (iii) dipping the dried end face portion again in an aqueous metal salt solution whose metal species is the same as that in the aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; and (iv) performing a calcination treatment to harden the catalytic end face. | 02-18-2010 |
| 20110028309 | SLURRY FOR PRODUCTION OF DENITRATION CATALYST, PROCESS FOR PRODUCING THE SLURRY, PROCESS FOR PRODUCING DENITRATION CATALYST USING THE SLURRY, AND DENITRATION CATALYST PRODUCED BY THE PROCESS - Disclosed are a slurry for the production of a denitration catalyst, which allows a catalytically active component to be present in the inner region of a ceramic fiber sheet so as to achieve extension of the catalyst life and also allows the production process to be shortened so as to reduce the production cost; a process for producing the slurry; a process for producing a denitration catalyst using the slurry; and a denitration catalyst produced by the process. The slurry of the invention for producing a denitration catalyst comprises a silica sol, titania particles, metavanadic acid particles supported on the titania particles, metatungstic acid particles, and an organic acid ammonium salt. | 02-03-2011 |

| 20100260655 | AMMONIA SYNTHESIS APPARATUS AND PROCESS - An ammonia synthesis apparatus includes: a first gas channel; a second gas channel disposed outside the first gas channel; a third gas channel disposed outside the second gas channel; an air supply unit that supplies air to the second or third gas channel; a water supply unit that supplies water to the first gas channel; and a heat supply unit that supplies heat to the first gas channel. A metal or a metal oxide that reduces water to produce hydrogen is placed in the first gas channel. An ammonia synthesis catalyst is placed in the second gas channel located downstream of the downstream end portion of the first gas channel. The second and third gas channels are at least partially partitioned by an oxygen permeation membrane, or a nitrogen permeation membrane, so that oxygen is supplied to the third gas channel, and nitrogen is supplied to the second gas channel. | 10-14-2010 |
| 20110286907 | AMMONIA SYNTHESIS PROCESS - The invention provides a process for efficient synthesis of ammonia. The process includes a water-splitting step in which water is decomposed to obtain a first source gas comprising hydrogen and oxygen, a first oxygen removal step in which the oxygen contained in the first source gas is at least partially separated and removed by an oxygen separating membrane or hydrogen separating membrane to obtain a second source gas having a lower oxygen concentration than the first source gas, a second oxygen removal step in which the oxygen in the second source gas is reacted with hydrogen to produce water for removal, or is adsorbed onto an adsorption medium for removal, to obtain a third source gas having a lower oxygen concentration than the second source gas, and an ammonia synthesis step in which the hydrogen in the third source gas is reacted with nitrogen to synthesize ammonia. | 11-24-2011 |

| 20110283960 | AMMONIA-ENGINE SYSTEM - An ammonia-engine system is capable of supplying an ammonia cracking catalyst with a temperature necessary to promote a reaction even during low load operation in which a temperature of an exhaust gas from an ammonia engine is lower than an operating temperature of the ammonia cracking catalyst. In an ammonia-engine system provided with an ammonia engine ( | 11-24-2011 |
