催化裂化装置回炼加氢石脑油对产品的影响

加氢石脑油作为催化裂化装置急冷油进入提升管进行回炼,对回炼加氢石脑油期间产品分布和产品性质有较为明显的影响。干气、液化气和柴油收率明显下降,汽油收率明显升高,汽油辛烷值和芳烃含量也呈下降趋势,稳定汽油有效烯烃含量明显降低,对醚化反应操作有较大的影响。通过分析催化裂化装置回炼加氢石脑油对产品分布和产品性质的影响,为未来生产调整提供数据参考。

Effect of Catalytic Cracking Unit Refining Hydrogenated Naphtha on Products

In order to ensure the balance of production in the whole plant, hydrogenated naphtha as a catalytic cracking unit, quenching oil enters the riser for refining, which has a significant impact on product distribution and product properties during refining of hydrogenated naphtha, dry gas, The yield of liquefied gas and diesel oil decreased significantly, the gasoline yield increased significantly, the octane number and aromatics content of gasoline also decreased, and the effective olefin content of gasoline hydrogenation unit decreased significantly, which had a greater impact on the operation of etherification reaction. By analyzing the effects of reductive hydrogenated naphtha on the product distribution and product properties of the catalytic cracking unit, it provides a data reference for future production adjustment.
