减压蜡油加氢脱硫工艺及宏观动力学模型研究

摘要

The effect of reaction temperature , hydrogen partial pressure , LHSV , V (H2 )/V (oil) on the VGO hydrodesulfurization was studied and the trend of sulfur content in hydrotreated oil was also reflected based on correlated curves which were established on process conditions .Moreover a macro kinetic model of VGO hydrodesulfurization was set up and kinetic model parameters were correlated and validated by experiments .The results show this model held prediction accuracy .%以3种不同VGO为原料，在200 mL固定床连续等温加氢试验装置上，考察了反应温度、氢分压、体积空速、氢油体积比等工艺条件对加氢精制催化剂A脱硫反应的影响，同时建立了相应的关联曲线，探讨工艺条件对精制油中硫含量的影响趋势。建立了减压蜡油加氢脱硫宏观动力学模型，对动力学模型进行优化计算和实验验证，结果表明模型具有一定的预测精度。
