Abstract

The invention provides a method and device for determining the nitride proportion of a diesel oil hydrodenitrogenation reaction. The method comprises the following steps of S1, according to an isothermal hydrodenitrogenation kinetic model, calculating kinetic parameters of a diesel oil hydrodenitrogenation reaction, the kinetic parameters comprising a reaction pre-exponential factor and reaction activation energy of a diesel oil nitride, and S2, substituting the kinetic parameters into an adiabatic hydrodenitrogenation kinetic model, and calculating a first proportion of nitrides under adiabatic reaction conditions. Therefore, the adsorption characteristic of the nitride is considered, and the determined nitride proportion after the diesel oil hydrodenitrogenation reaction under the adiabatic reaction condition is more accurate.

Description

technical field [0001] The present disclosure relates to the field of kinetics of diesel hydrodenitrogenation reaction, and in particular, relates to a method and device for determining the proportion of nitrogen compounds in diesel hydrodenitrogenation reaction. Background technique [0002] In order to further improve the quality of clean fuels, diesel quality standards have been gradually raised. Hydrodenitrogenation technology is a key technology for producing clean diesel. The technology uses a hydrotreating catalyst to reduce sulfur, nitrogen and aromatics in diesel feedstock. Under the action of the diesel hydrodenitrogenation catalyst, the sulfur and nitrogen content in the diesel gradually decrease, and the polycyclic aromatic hydrocarbons gradually become saturated. In order to improve the performance of the catalyst, it is necessary to establish a kinetic model of the hydrodearomatization reaction in order to develop a high-performance diesel hydrogenation catal...
