Problems solved by technology

However, this kind of blended diesel faces some problems. Since methanol is a polar molecule and the alkane components in diesel oil are non-polar molecules, the mutual fusion effect of methanol and diesel in methanol diesel is not obvious, and its preparation process is relatively complicated. , not conducive to large-scale promotion

Embodiment 1

[0031] A kind of clean composite diesel oil described in the present embodiment comprises following raw materials in parts by weight: 30 parts of castor oil, 5 parts of isooctane, 10 parts of xylene, 15 parts of methyl alcohol, 20 parts of isopropanol, 20 parts of diesel crude oil, In this embodiment, diesel oil is 0# diesel oil.

[0032] The preparation method of the clean composite diesel described in this example is: take methanol, xylene, and diesel crude oil in the mixing mixer according to the above weight parts, and stir until there is no obvious layering at 35 ° C. That is, methanol and diesel crude oil are fully dissolved in xylene; then take castor oil, isooctane, and isopropanol in the above-mentioned mixing mixer according to the above weight parts, and mix with the mixed xylene, methanol, and diesel crude oil, At this time, at 40°C, carry out thorough mixing and stirring until the stirring is uniform without stratification, and the composite diesel oil is obtained...

Abstract

The invention discloses clean composite diesel oil and a preparation method therefor. According to the clean composite diesel oil and the preparation method therefor, the clean composite diesel oil is high in stability and easy to store, the emission of nitrides and sulfides after combustion can be greatly lowered, and thus, the clean composite diesel oil is pollution-free to environments; and meanwhile, no glycerine substance is added, soap cannot be formed to block up an oil pipeline and a carburetor jet, and thus, the cleanness of pipelines of an engine is guaranteed. According to the clean composite diesel oil and the preparation method therefor, disclosed by the invention, the clean composite diesel oil is high in stability and easy to store, the emission of the nitrides and sulfides after combustion can be greatly lowered, and thus, the clean composite diesel oil is pollution-free to the environments; meanwhile, no glycerine substance is added, soap cannot be formed to block up the oil pipeline and the carburetor jet, and thus, the cleanness of the pipelines of the engine is guaranteed; and meanwhile, the preparation method is simple, thereby being beneficial to large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of fuel oil, and in particular relates to a clean compound diesel oil and a preparation method thereof. Background technique [0002] Diesel is the fuel for diesel engines. It is mainly prepared from diesel fractions produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking, etc. At the same time, diesel is a light petroleum product, which is a complex hydrocarbon mixture, and Contains a large amount of N, S and other elements. After combustion, these elements combine with oxygen to form nitrogen compounds, oxides and other gases that pollute the environment; and diesel oil contains a small amount of impurities, which form granular dust after combustion. cause air pollution. [0003] In order to reduce the pollution produced and discharged by diesel combustion and solve the problem of pollutant discharge from the source, biodiesel has been proposed, by adding ...
