    • The present invention relates to a catalyst for removing NOx contained in exhaust gas, more specifically to a catalyst for removing NOx using metal titanate as a support. The catalyst for removing NOx according to the present invention allows metal titanate to act as a support as well as an adsorption and storage agent (hereafter an adsorption/storage agent) of NOx in lean-burn conditions. Supported noble metals or transition metal components provide a catalyst function which helps adsorption/storage by oxidizing NOx into NO2 in lean-burn conditions and participates in the reaction of reducing the adsorbed and stored NO2 into N2 in fuel-rich conditions. The catalyst according to the present invention has twice the NOx storage amount of conventional catalysts, for example Ba, and enables effective removal even in operational conditions of a wider range than 150˜700° C. In addition, practical use which has been impossible until now is enabled due to the stable NOx removal capability even in conditions where SOx is present in exhaust gas.
    • 本发明涉及一种用于除去排气中所含的NOx的催化剂,更具体地说,涉及使用金属钛酸盐作为载体除去NOx的催化剂。 根据本发明的用于除去NOx的催化剂允许金属钛酸盐作为稀燃条件下的NOx的吸附和储存剂(以下称为吸附/储存剂)作为载体。 负载的贵金属或过渡金属组分提供了催化剂功能,其通过在稀燃条件下将NO x氧化成NO 2来帮助吸附/储存,并且参与在富含燃料的条件下将吸附和储存的NO 2还原成N2的反应。 根据本发明的催化剂具有常规催化剂例如Ba的二氧化碳储存量的两倍,并且即使在比150℃至700℃更宽的范围的操作条件下也能够有效去除。另外,实际使用已经不可能直到 即使在废气中存在SOx的条件下,也能够实现稳定的NOx去除能力。

    • The present invention provides a large-scale solid oxide fuel cell stack and a method of manufacturing the stack. In the present invention, a segmented cell tube (103a, 103b) is formed in such a way that unit cells connected to each other are formed on a cylindrical or flat tubular porous support (101). A reformer tube (102) is configured such that reforming catalyst (3) is provided in a support (101). The cell tube and the reformer tube are disposed at positions spaced apart from each other such that an air passage is formed on the outer surface of the reformer tube. A cell module (105) is formed by arranging the tubes such that a fuel gas flow passage is formed between the tubes. The solid oxide fuel cell stack is formed by integrating cell modules with each other.
