Abstract
Спосіб одержання олефінів і бензину із низьким вмістом бензолу із нафти, який включає наступні стадії:(1) проведення екстрактивної перегонки нафти із одержанням нафтового екстракту, який містить циклоалкани і ароматичні вуглеводні, і очищеної нафти, яка містить алкани і С-циклоалкани, при цьому масове відношення між С-циклоалканами, які містяться в очищеній нафті, і С-циклоалканами, які містяться в нафті, становить 80-95 %;(2) контактування нафтового екстракту із каталізатором риформінгу в реакційних умовах каталітичного риформінгу: 0,01-3,0 МПа, 300-, молярне відношення водень/вуглеводні 0,5-20 і об'ємна (волюмометрична) швидкість 0,1-50 год.з одержанням риформату із низьким вмістом бензолу; і(3) подача очищеної нафти в установку парового крекінгу для здійснення реакції крекінгу із одержанням легких олефінів, що приводить до підвищеного ступеня використання нафти і до одержання компонента бензину із низьким вмістом бензолу додатково до виробництва із нафти етилену, пропілену і бутадієну із підвищеними виходами.A method of obtaining low-benzene olefins and gasoline from petroleum, comprising the following steps: (1) performing extractive distillation of oil to obtain an oil extract containing cycloalkanes and aromatic hydrocarbons, and purified oil containing alkanes and C-cycloalkanes the mass ratio between C-cycloalkanes contained in the purified oil and C-cycloalkanes contained in the oil is 80-95%; (2) contacting the oil extract with the reforming catalyst under the catalytic reforming reaction conditions: 0.01-3, 0 MPa, 300-, a molar ratio of hydrogen / hydrocarbons of 0.5-20 and a volumetric (volumometric) speed of 0.1-50 hours to obtain a reformate with low benzene content; and (3) supplying the purified oil to a steam cracking unit to effect a cracking reaction to produce light olefins, resulting in an increased degree of oil use and a low benzene content of the benzene component in addition to the production of ethylene, propylene and butadiene oil from the increased.
