柴油加氢处理工艺研究进展

Research Progress of Diesel Hydrotreating Process

随着环保法案的日益严格,对柴油质量的要求也在逐步提高。因此,开发一种高效环保的柴油加氢处理工艺显得尤为关键。利用柴油加氢处理技术使劣质柴油馏分得到全面改善,达到低硫、高十六烷值的柴油产品标准。论述了国内外常用的柴油加氢处理技术,及对每种工艺的原理迚行详细阐述,相应地列举了在工业中的应用,幵就今后的发展方向作了说明。

With the increasingly stringent environmental protection, the demand for diesel quality is gradually increasing. Therefore, it is very important to develop an efficient and environmentally friendly diesel hydrotreating process. These technologies are used to improve the fraction of low-grade diesel oil to meet the standard of low sulfur and high sixteen alkane diesel products. In this paper, common diesel hydrotreating technologies at home and abroad were discussed, and the principle of each process was expounded. Then their application was listed, and the future development direction was analyzed.
