Comparison of gas and kerosene oils chemical composition before and after hydrotreating using comprehensive two-dimensional gas chromatography

Abstract

Information on the detailed composition of the feedstock and product from the hydrotreating is essential for a better understanding of the reactions, possible optimization of the process conditions, development of new catalysts, and achieving a better overall performance of the diesel fuel, especially in terms of environmental impact. This work aims to determine the detailed composition of the gas and kerosene oils before and after hydrotreating to validate the performance of the hydrotreating. Comprehensive two-dimensional gas chromatography (GC×GC) was chosen as an effective analytical characterization tool for supporting such initiatives. The quantitative group hydrocarbon and sulfur compounds compositions were determined using GC×GC with flame ionization detector (FID) and selective chemiluminescence detector (SCD), respectively.
