| 摘 要： | 根据加氢精制和加氢改质过程化学反应的特点，设计了分区进料柴油加氢改质MHUG-Ⅱ工艺技术，并在中型实验装置上对其效果进行了验证。并考察反应参数对产品分布和产品性质的影响，同时进行MHUG-Ⅱ技术原料油适应性试验。结果表明，与同样条件常规加氢改质工艺相比，MHUG-Ⅱ工艺技术柴油馏分收率可提高8.41百分点，产品柴油十六烷值高2.7个单位，石脑油馏分芳烃潜含量高3.9百分点，改质反应过程选择性明显提高；且对各类催化裂化柴油、直馏柴油以及焦化柴油具有良好的适应性，是炼油厂生产清洁柴油的优选技术。

| Abstract: | Based on the intensive studies on the chemical reactions of hydrotreating and hydroupgrading process,a flexible hydroupgrading process,MHUG-Ⅱ,having three reaction zones and separate feeding systems was developed and put into practice in pilot plant.The influence of reaction parameters on the product distributions and product qualities was investigated,as well as the adaptability of MHUG-Ⅱ process to various feedstocks.Test results showed that as comparing with conventional hydroupgrading process under similar operating conditions,during MHUG-Ⅱ process the yield of diesel fraction increased 8.41 percentage points,the cetane number of treated diesel was higher 2.7 units and the potential content of aromatics in naphtha was 3.9 percentage points more.MHUG-Ⅱ process enhances the selectivity of hydroupgrading reactions significantly;it is an optimum approach to be used to produce clean diesel fuel from various inferior feedstocks including FCC light cycle oil,straight-run diesel fraction and coker gas oil economically. |
