    • This invention relates to a discoloration indicator for checking the life span of a desulfurization adsorbent, and a desulfurization reactor and a desulfurization system including the same, and specifically, to a discoloration indicator for checking the life span of a desulfurization adsorbent able to effectively adsorb and remove organic sulfur compounds from fossil fuels, including natural gas or LPG containing the organic sulfur compound, and to a desulfurization reactor and a desulfurization system including the same. This invention makes it possible to remove the organic sulfur compound using the desulfurization adsorbent and to check the replacement time of the adsorbent with the naked eye or using an electrical signal, and thus may be applied to the treatment of natural gas or LPG requiring desulfurization, and also to hydrogen generators for home fuel cell generation systems or distributed fuel cell generation systems requiring that devices be simple, or requiring unmanned operation.
    • 本发明涉及一种用于检查脱硫吸附剂寿命的变色指示剂,脱硫反应器和包括该脱硫反应器和脱硫系统的脱硫系统,具体涉及用于检查能够有效吸附的脱硫吸附剂的寿命的变色指示剂 从包括天然气或含有机硫化合物的LPG的化石燃料中除去有机硫化合物,以及脱硫反应器和包括该脱硫反应器的脱硫系统。 本发明可以使用脱硫吸附剂除去有机硫化合物,并且用肉眼检查吸附剂的更换时间或使用电信号,因此可以应用于需要脱硫的天然气或LPG的处理, 还有用于家用燃料电池生成系统的氢发生器或需要设备简单或需要无人操作的分布式燃料电池生成系统。

    • Disclosed herein are a platinum-based catalyst for oxidation/reduction reactions and the use thereof. The platinum-based catalyst is prepared by loading a catalyst composition comprising a water-soluble salt of at least one metal selected from among cerium (Ce), zirconium (Zr) and rhenium (Re), on a support comprising at least one selected from among alumina, silica and titania. The disclosed catalyst can be prepared in a simple manner without any particular limitation as to the kind of usable water-soluble platinum salt, and when it is applied to various oxidation reactions, including water gas shift reactions of carbon monoxide, three-way catalytic reactions, and selective oxidation reactions of carbon monoxide, and to reduction reactions, such as reactions of removing nitrogen oxide (NOx), it will show excellent catalytic activity. In particular, the disclosed catalyst shows excellent performance even in a specific temperature range in which it is difficult to apply the prior high-temperature water gas shift reaction catalyst and low-temperature water gas shift reaction catalyst. Also, it can remove carbon monoxide even at high temperatures without the loss of hydrogen caused by methanation, and thus is particularly useful in a hydrogen production process of producing high- purity hydrogen for fuel cells.
    • 本文公开了用于氧化/还原反应的铂基催化剂及其用途。 通过将包含选自铈(Ce),锆(Zr)和铼(Re))的至少一种金属的水溶性盐的催化剂组合物载载在包含至少一种选自以下的至少一种的载体上来制备铂基催化剂: 在氧化铝,二氧化硅和二氧化钛中。 所公开的催化剂可以以简单的方式制备,对于可用的水溶性铂盐的种类没有特别的限制,并且当它被应用于各种氧化反应时,包括一氧化碳的水煤气变换反应,三元催化反应 ,一氧化碳的选择性氧化反应,还原反应如去除氮氧化物(NOx)的反应,将显示出优异的催化活性。 特别地,所公开的催化剂即使在难以应用现有的高温水煤气变换反应催化剂和低温水煤气变换反应催化剂的特定温度范围内也显示出优异的性能。 此外,即使在高温下也可以除去一氧化碳,而不会由甲烷化引起的氢的损失,因此特别适用于制造用于燃料电池的高纯度氢气的氢气生产方法。
