| 20110268242 | Hydrogen and Oxygen Recombination Catalyst, Recombination Apparatus, and Nuclear Plant - A recombination apparatus is provided to an off-gas system of a boiling water nuclear plant. An off-gas system pipe connected to a condenser is connected to the recombination apparatus. A catalyst layer filled with a catalyst for recombining hydrogen and oxygen is disposed in the recombination apparatus. The recombination catalyst has a percentage of the number of Pt particles whose diameters are in a range from more than 1 nm to not more than 3 nm to the numbers of Pt particles whose diameters are in a range from more than 0 nm to not more than 20 nm, falling within a range from 20 to 100%. The condenser discharges gas containing an organosilicon compound (ex. D5), hydrogen, and oxygen, which is introduced to the recombination apparatus. Use of the above recombination catalyst can improve the performance of recombining hydrogen and oxygen more than conventional catalysts and the initial performance of the catalyst can be maintained for a longer period of time. | 11-03-2011 |
| 20100210887 | CATALYST FOR PRODUCING A LIGHT OLEFIN AND METHOD FOR PRODUCING A LIGHT OLEFIN - A catalyst for producing a light olefin including a pentasil-type zeolite, alkaline earth metal atoms and aluminum atoms contained in the pentasil-type zeolite satisfying the following atomic ratio: [alkaline earth metal atom/aluminum atom]=0.2 to 15, the average value of the gradient of an adsorption isotherm of the pentasil-type zeolite measured by the nitrogen adsorption method being 30 or more at a relative pressure of 0.2 to 0.7. | 08-19-2010 |
| 20090324454 | PURIFICATION CATALYST FOR REFLOW FURNACE GAS, METHOD FOR PREVENTING CONTAMINATION OF REFLOW FURNACE, AND REFLOW FURNACE - A purification catalyst which prevents contamination within a reflow furnace, including flux components, while suppressing the generation of CO is provided. | 12-31-2009 |
