Problems solved by technology

At present, oil refining industry at home and abroad mainly uses oil as raw material, but the existing oil refining process cannot completely solve the problem of high emissions of carbon, sulfur, nitrogen and other substances in diesel oil, and the simple use of oil cannot make full use of my country's more coal and less oil.

Embodiment 1

[0030] The percentages of raw materials used in this example are: higher alcohols 13%, aromatics 4%, n-paraffins 45.5%, white oil 17.5%, polymethoxy dimethyl ether DMM3-6 1%, coal-based Fischer-Tropsch synthetic liquid wax 18%, cetane number improver 1%.

[0031] The sources, selection requirements or uses of the above raw materials are as follows:

[0032] High-carbon alcohols are products obtained by separating C9-C15 straight-chain and isomeric fatty alcohols with a mass fraction of not less than 95% after oxygen-containing oil (heavy) is treated; the specific process of the above-mentioned treatment is: In the oxygenated oil (heavy weight) with a mass fraction of C9-C15 linear and isomeric fatty alcohols not less than 85%, add potassium hydroxide with a mass fraction of 50% according to 0.1% of the mass of the oxygenated oil (heavy weight) Aqueous solution, after 30-45 minutes of continuous reaction, settling at 20-40°C for 24-36 hours, separating the pasty esters in the ...

Embodiment 2、3、4

[0047] Embodiment 2, 3, 4 are all identical with the raw material category that embodiment 1 adopts, process parameter, and difference is: the higher carbon alcohol that adopts, aromatic hydrocarbon, normal paraffin, white oil, polyoxymethylene dimethyl ether The mass fractions of DMM3-6, coal-based Fischer-Tropsch synthetic liquid wax, and cetane number improver are different, and the mass fractions are shown in Table 1.

Abstract

The invention discloses an alcohol-based fuel for a compression ignition type internal combustion engine and a preparation method of the alcohol-based fuel. The alcohol-based fuel is prepared from the following raw materials in percentage by mass: 40 to 45.5 percent of n-alkane, 13.5 to 17.5 percent of white oil, 13 to 15 percent of high alcohol, 4 to 7 percent of aromatic hydrocarbon, 1 to 3 percent of polyoxymethylene dimethyl ether DMM3-6, 18 to 21 percent of coal-based Fischer-Tropsch synthesis liquid wax and 0.5 to 1 percent of cetane number improver. The main raw materials are derived from a coal-to-oil process and value-added utilization of oxygen-containing oil (heavy), the raw materials are convenient to obtain and low in price, the production cost of enterprises and the use cost of terminal users are reduced, compared with diesel oil, the product has the advantages that the emission of carbon, sulfur and oxynitride is reduced, the heat efficiency is improved, and in the preparation process, besides the treatment of high-carbon alcohol and the earlier-stage process, the production cost is reduced. Core preparation sections of the alcohol-based fuel all adopt continuous physical embedding reaction at normal temperature and pressure, so that the energy consumption and the safety risk are reduced.

Description

technical field [0001] The invention relates to the field of coal-based alcohol-based fuels, in particular to an alcohol-based fuel for compression ignition internal combustion engines and a preparation method thereof. Background technique [0002] With the rapid growth of my country's economy, people's living standards are improving day by day, and the number of cars is increasing rapidly, resulting in continuous growth in the demand for vehicle fuel in recent years, becoming the world's largest oil importer, and my country is a country with more coal and less oil. In 2021, 512.98 million tons of oil will be imported. At the same time, the increase in the number of vehicles has led to an increase in the emission of harmful substances, resulting in increasingly serious air pollution, especially the exhaust emissions of compression ignition vehicles. The emission of harmful substances has caused serious harm to humans and the environment. It is very harmful and directly threate...
