用 3层前馈网络根据柴油馏分油性质、工艺条件对产品中硫的质量分数进行了预测 ,考察了原料油性质和工艺条件对加氢脱硫反应 (H DS)的影响。结果表明 ,工艺条件对 HDS反应深度影响的顺序为 :反应温度 >空速 >氢对原料油体积比 >氢分压 ;原料油性质对反应深度影响顺序为 :密度 >50 %馏出点 >氮质量分数 >硫质量分数 The three-layer feedforward network was used to predict the mass fraction of sulfur in the product according to the nature and process conditions of the diesel distillate. The effects of the nature of the feedstock and the process conditions on the hydrodesulfurization reaction (H DS) were investigated. The results showed that the order of reaction temperature, space velocity, hydrogen to feedstock volume ratio, partial pressure of hydrogen was the order of influence of process conditions on HDS reaction depth. The order of effect of feedstock properties on reaction depth was as follows: density> 50% Mass fraction> sulfur mass fraction
