| Application of the multidimensional chromatogram in the petrochemical industry Summary:This thesis has recommended the development, theory of multidimensional chromatography and its application to solve problems in the petrochemical industry. The solution of the multidimensional chromatography used in petrochemical industry could be enwiden its scope to the similar problems in other fields. This thesis can offer some help for chromatography workers. The full text is divided into four chapters.Chapter one is the introduction part to introduce meaning, development and theory of multidimensional chromatography and its application in the petrochemical industry and the ideas of multidimensional chromatogram in solving the problem.Chapter two is about tandem double columns and its application in the low carbon hydrocarbon analysis.Chapter three is about Precut technique, Heart Cut technique and DEANswith technique used in the low carbon hydrocarbon analysisChapter four Multidimensional PONA analysis instrument was used to analyze the raw materials for the production of ethylene, to develop the expansion application of PONAanalysis to the optimization of the carbon number of the hydrogen craft in the cracked petrol. |
