In-situ Catalyst Characterization System transforms capabilities of existing test apparatus
 |
美国佐治亚州诺克罗斯市 - 2020年1月8日，Micromeritics Instrument Corp.是材料表征技术的领导者，正在看到研究人员热衷于使用新的Micromeritics In-Aittu催化剂表征系统（ICC）增强异质催化剂研究的完整性通过在现有的反应筛选系统中添加新功能。标准实践是从反应器中除去催化剂，并将其转移到一个反应后表征A的单独系统中，但这可能会冒着环境污染和损害数据质量的风险。使用ICC，可以在反应器中的任何一点表征催化剂，以获取代表性数据。ICC的广泛兼容性使这种对反应，失活和再生的极为宝贵的见解广泛访问。
“Researchers use a wide range of different apparatus to assess catalyst performance,” said Dr Simon Yunes, Senior Scientist, Micromeritics, “from in-house glassware units to sophisticated, automated systems such as our Micromeritics Microactivity Effi reactor. Following a reaction, it is desirable to re-quantify defining characteristics such as the number of active catalysts sites to observe any change. This typically means removing the catalyst from the reactor and transferring it to a chemisorption system. There is widespread recognition that this process undermines the integrity of the resulting characterization data, so we’re delighted to be able to offer a solution which so many people can use.”
The ICCS can be connected to most existing, flowing test rigs, to deliver an extensive range of well-established catalyst characterization capabilities. The ability to simply add on this functionality enhances the value of existing equipment and makes the ICCS a valuable addition. The characterization techniques it enables include pulsed chemisorption and temperature programmed analyses (reduction, oxidation and desorption) which are applied to measure performance-defining metrics such as number of active sites, metal dispersion and activity under specific conditions. These analyses can be carried out at pressures up to 20 bar, depending on the rating of the attached apparatus, and the conditions of interest.
“We’ve had excellent feedback from leaders in the field of catalyst development, who are already using the ICCS to access new information to drive their studies,” said Dr Yunes “A better understanding of the mechanisms of the reaction, catalyst deactivation, and regeneration are crucial for the commercialization of higher performance catalysts. The ICCS is a powerful solution for any researcher looking to efficiently augment and enhance their heterogeneous catalyst characterization strategies.”
