妙文翻译公司翻译样稿3.我们研发的烟气脱硝催化剂有什么创新?What’s the innovation of our flue gas De-NOx catalyst?我们研发的烟气SCR脱硝催化剂有什么创新?概括为下列四个创新点:What’s the innovation of our flue gas SCR De-NOx catalyst? In general, there are four innovations (as follows):3.1原料二氧化钛从颜料型改性为材料型3.1 Raw titanium dioxide is modified from pigment-type to material-type我国的钛白粉厂生产的二氧化钛都是颜料型的,它从颜料角度对二氧化钛的质量从白度、着色力、遮盖力、吸油量、储缶稳定性等考虑。

而生产SCR脱硝催化剂的二氧化钛必须要从材料角度对二氧化钛提出比表面、孔容、最可几孔径分布、表面酸性、晶粒大小、结晶庋好坏……方面考虑。

因为国内钛白粉厂还没有掌握颜料型二氧化钛向材料型二氧化钛改性技术。

因此,生产的二氧化钛不能用于SCR脱硝催化剂生产。

被迫材料型二氧化钛必须花大量外汇进口。

三龙公司通过大量实践,另辟捷径,掌握了二氧化钛从颜料型改性为材料型的“绝窍”。

而且制备的材料型二氧化钛从比表面、孔容、最可几孔径分布、表面酸性、晶粒大小、结晶庋好坏……等方面都超过进口的二氧化钛。

The titanium dioxide produced by China’s t itanium dioxide plants are of pigment-type, which will consider the quality from the pigment aspect: whiteness, tinting strength, hiding capacity, oil absorption, storage stability and so on. However, the titanium dioxide used for SCR De-NOx catalyst production must consider from the material aspect: specific surface area, pore volume, most probable distribution of diameter, surface acidity, grain size, crystalline status and so on. Since the domestic titanium dioxide plants have not mastered the modification technology from pigment-type to material-type, the produced titanium dioxide cannot be used for SCR De-NOx catalyst production. As a result, the material-type titanium dioxide must be imported with large foreign exchange. Through plentiful practice, Zhejiang Sanlong Catalyst Co., LTD has open up a ne w shortcut and has mastered the “wizardry” of modification. And the produced material-type titanium dioxide has exceeded the imported titanium dioxide from the aspects of specific surface area, pore volume,most probable distribution of diameter, surface acidity, grain size, crystalline status and so on.3.2辅助催化剂的优势3.2 Advantages of secondary catalyst三龙公司在开发国产SCR脱硝剂过程中,别具一格、独具匠心地在辅助催化剂上有创新。

自己合成、结构式为[H z][Al2-x H x][Si4-y Al y]O10[OH]2的硅铝氧化物对蜂窝状SCR脱硝催化剂成型有贡献;对改善催化剂性能、增加催化剂强度也有突出的贡献。

Zhejiang Sanlong Catalyst Co., LTD has made a unique and distinctive innovation for secondary catalyst during the development of domestic SCRDe-NOx agent. Their synthetic Si-Al oxide (with a structural formula of[H z][Al2-x H x][Si4-y Al y]O10[OH]2) made a special contribution to the honeycomb SCR De-NOx catalyst; also, it had an outstanding contribution to improve catalyst performance and strength.3.3独特的工艺,钒价态的调控3.3 Unique process & vanadium valence state regulation独特的工艺,钒价态的调控,使催化剂活性组份钒的价态发挥到最佳程度。

因此,对放置在高尘区的SCR脱硝催化剂,防磨蚀一定要考虑。

国外对SCR脱硝催化剂迎风面的抗磨蚀处理是浸上一层类似水玻璃的硬化物,以增强迎风面的抗磨蚀能力。

本发明也是独具匠心地开发了一种冷喷涂技术,不但增强了SCR脱硝催化剂迎风面的抗磨蚀能力,而且还具有一定的催化活性。

The dust in flue gas is mainly composed of alumina and silica; these small particles, driven by high speed air steam, will abrade the structures colliding with them (like knifes), and they can even cut the steel supports. Therefore, anti-abrasion must be considered for SCR De-NOx catalyst used within dusty areas. In foreign countries, the anti-abrasion treatment for the windward side is realized by soaking a layer of hardening material (like water glass) to enhance the anti-abrasion ability. This invention has also distinctively developed a kind of cold spraying technology, not only the anti-abrasion ability on windward side is enhanced, but also it has certain catalytic activity.版权所有，妙文上海翻译公司()，如有转载，请注明出处。
