摘　　要：根据柴油馏分组成和加氢降凝过程中的烃类反应规律,中国石化大连石油化工研究院(FRIPP)通过优化降凝催化剂和加氢催化剂级配组合方式,开发了新型高效节能加氢降凝技术。该技术在某炼油厂200万t·a^(-1)柴油加氢降凝装置上获得成功应用,解决了上周期装置使用常规加氢降凝技术时存在柴油收率偏低、能耗和氢耗高的问题。采用新型加氢降凝技术之后,该装置降凝反应器的入口和出口的温差由上周期的-19.5℃改善为本周期的-3.8℃,反应热利用效率大幅度提高,能耗和氢耗显著降低,目的产品-20号柴油的收率提高了3.6个百分点,产品质量满足指标要求,实现了增产低凝柴油和节能降耗的目标。According to the composition of diesel and hydrocarbon reaction characteristics in the process of hydrodewaxing, FRIPP has developed a new high efficiency and energy saving hydrodewaxing technology by optimizing the grading combination of hydrodewaxing catalyst and hydrotreating catalyst. The successful application of this technology in 2.0 Mt·a^(-1)hydrodewaxing unit solves the problems of low diesel yield, high energy and hydrogen consumption when conventional hydrodewaxing technology was applied in the last operation cycle. After adopting the new hydrodewaxing technology, the temperature difference between the inlet and outlet of the hydrodewaxing reactor was improved from-19.5 ℃ to-3.8 ℃, the utilization efficiency of reaction heat was greatly improved, and the energy and hydrogen consumption of the unit were significantly reduced. In addition, the yield of main product-20;diesel was increased by 3.6 percentage points and the product quality met the requirement, which achieved the goal of increasing production of low solidification point diesel and saving energy and reducing consumption.
