公开(公告)号:CN101148616公开(公告)日:2008.03.26这是一种由裂解汽油生产清洁汽油的方法。裂解汽油进入常压分馏塔进行馏分分离,得到轻质裂解汽油和重质裂解汽油,切割点为78～85℃;重质裂解汽油与氢气混合后进入加氢反应区,在加氢精制催化剂的作用下进行反应,其反应生成物经冷却、气液分离后得到汽油产品。采用本发明提供的方法,可以用裂解汽油直接生产低硫、低苯含量、高辛烷值的清洁汽油产品或高性能的高辛烷值清洁汽油调和组分,有效扩大清洁汽油的来源,改善现有商品汽油的构成。
Public (announcement) No .: CN101148616 Publication date: 2008.03.26 This is a method for producing clean gasoline from pyrolysis gasoline. The pyrolysis gasoline enters the atmospheric fractionating tower to be fractionated to obtain light pyrolysis gasoline and heavy pyrolysis gasoline with cutting point of 78-85 ° C .; the heavy pyrolysis gasoline is mixed with hydrogen and then enters the hydrogenation reaction zone, Under the action of reaction, the reaction product is cooled, gas-liquid separation to obtain gasoline products. The method provided by the invention can directly produce pyrolysis gasoline with low sulfur content, low benzene content and high octane value or high-performance high-octane gasoline blending component with cracked gasoline to effectively expand the sources of clean gasoline and improve The composition of existing products gasoline.
