Embodiment 1

[0019] A preparation method of environment-friendly C9 fuel oil, using ethylene cracking by-product C9 fraction with a distillation range of 80-190°C as raw material, adding extractant NMP and placing it in a constant temperature water bath at 30°C to stir and mix for 1 hour. The amount of extractant added is The volume ratio with the raw material is 1: 1, and the separation is allowed to separate for 1h. Add the additive oligomer to the separated oil phase and continue to stir for 1h to obtain the product. The amount of the oligomer added is 4-4% of the weight of the separated oil phase. 8%.

[0020] The additives include the following components and parts by weight: methane 90, isopropane 6, ethylene 1, cyclopentane 2, benzene 0.8.

[0021] Gained C9 fuel oil is tested and the results are as follows:

Abstract

The invention relates to a preparation method of environment-friendly C9 fuel oil. The preparation method of the environment-friendly C9 fuel oil comprises the following steps of: based on a fraction with the boiling range of 80 to 190 DEG C in the byproduct C9 fraction from ethylene cracking as a raw material, adding an extraction agent, placing in a water bath with the constant temperature of 30 DEG C, stirring for 1h, standing and layering for 1h, adding an additive in the separated oil, and continuing stirring for 1h to obtain the environment-friendly C9 fuel oil. In comparison with the prior art, the environment-friendly C9 fuel oil has the advantages of less sulphur content, good dispersibility and the like.

Description

technical field [0001] The invention relates to the field of C9 fuel oil, in particular to a preparation method of environment-friendly C9 fuel oil. Background technique [0002] C9 fuel oil is a by-product separated from gasoline hydrogenation in ethylene production units. At present, C9 fraction is an ideal fuel to replace diesel oil due to its high calorific value. It is widely used in boiler burners, smelting, aluminum product production and other industries, but C9 fuel SO produced by combustion of organic sulfur compounds in oil x It seriously pollutes the atmosphere and has a heavy odor, which affects its quality and application. The desulfurization of general fuel oil usually adopts extraction technology, but the composition of C9 fuel oil is different from that of gasoline and diesel oil, and the extraction agent used for desulfurization of gasoline and diesel oil is not suitable for desulfurization of C9 fuel oil, and the content of aromatics in C9 fuel oil is rel...
