In this work, we propose a new kinetic model for HDS. The model is based on using GC-AED (Gas Chromatography - Atomic Emission Detection) to characterise the sulfur components in the oil fraction. The spectrum is divided into many small parts corresponding to approx. 1 °C TBP, each one considered as a pseudo-component. In addition, a few components with particularly low reactivity, like 4-Me-DBT and 4,6-Me-DBT, are identified and modeled separately. These components are important when the model must be accurate at high conversions. [Pg.190]
