生物乙醇脱水制乙烯反应产物的在线分析GC-tcd气相色谱仪
生物乙醇脱水制乙烯反应产物的在线分析GC-tcd气相色谱仪 详细信息:
浩瀚色谱(山东)应用技术开发有限公司研发生物乙醇脱水制乙烯反应产物的气相色谱在线分析方法及装置,其方法是先将生物乙醇脱水制乙烯反应产物分两路,一路进入产品收集装置,另一路通过载气进入色谱柱,在温度为80~150℃范围内,用色谱柱将乙烯,水,乙醛,乙醇,乙mi和丙tong分离,然后将分离后的各组分导入热导池检测器,在200~250℃下检测乙烯,水,乙醛,乙醇,乙mi、bing酮和其它副产物的含量,解决了以往分析技术中存在生物乙醇脱水后生成的产物中存在的操作繁琐,劳动强度大,不能即时观察到反应状态等缺点,色谱条件能使待测组分的响应值非常接近,其面积归一化法和各组分的相对质量百分数相似,只需1次进样就可以完成乙烯,水,乙醛,乙醇,yi醚及丙tong的定量测定,可用于生物乙醇脱水制乙烯反应的自动化在线分析。

On line analysis of reaction products from dehydration of bioethanol to ethylene GC-TCD gas chromatograph
On line analysis of reaction products from dehydration of bioethanol to ethylene Details of GC-TCD gas chromatograph:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed an online gas chromatography analysis method and device for the reaction products of bioethanol dehydration to ethylene. The method is to first divide the reaction products of bioethanol dehydration to ethylene into two paths, one path into the product collection device, and the other path into the chromatographic column through the carrier gas. Within the temperature range of 80~150 ℃, ethylene, water, acetaldehyde, ethanol, ethylamine and propylene are separated by the chromatographic column, Then, the separated components were introduced into a thermal conductivity cell detector to detect the content of ethylene, water, acetaldehyde, ethanol, ethylmi, bing ketone, and other byproducts at 200-250 ℃. This solved the problems of cumbersome operation, high labor intensity, and inability to observe the reaction state in real time in previous analytical techniques, such as the products generated after bioethanol dehydration. The chromatographic conditions can make the response values of the tested components very close, The area normalization method is similar to the relative mass percentage of each component. Only one injection is needed to complete the quantitative determination of ethylene, water, acetaldehyde, ethanol, yi ether and propyl tong, which can be used for the automatic online analysis of the dehydration of bioethanol to ethylene reaction.
