title: Differential fraction-based kinetic model for simulating hydrodesulfurization process of petroleum fraction.
abstract: A differential fraction-based kinetic model (DFKM) was proposed to simulate the reaction process in view of the extremely large number of compounds in the petroleum fraction. The results of the simulation experiment on the hydrodesulfurization (HDS) process demonstrated that without considering the exact compounds, DFKM can depict the reaction processes not only of the whole petroleum fraction but of any narrow cut we are interested in. Apparently, this kind of ability, which can be considered as the 'zoom in/out' function, is very useful for the further study on the processing techniques of the petroleum fraction. In the meantime, different methods for obtaining the functions needed in DFKM were investigated and satisfactory results were presented.
