Problems solved by technology

In order to reduce the pollution caused by smoke and dust, and its sulfur oxide (SOx) pollution is also a problem. In the existing technology, the PM2.5 content of vehicle exhaust emissions is relatively high, and the improvement of oil quality can reduce air pollution. It is in line with the policy of environmental protection and sustainable development, but in many cases, it solves technical problems such as power drop, high fuel consumption, corrosion, swelling, cold start difficulty, high temperature air resistance and other technical problems when the content of low nitrogen diesel oil is 10-55%, so Need a kind of preparation method of tail gas cleaning agent

[0025] A preparation method of tail gas cleaning agent, S1, selected raw materials: No. 200 oil component oil, methanol, composite additives and vapor pressure regulator;

[0026] S2, mixing the vapor pressure regulator evenly and adding it to methanol to form a blend;

[0027] S3, adding the composite additive into the blend;

[0028] S4, after slight stirring, inject into No. 200 oil component oil;

[0029] S5, putting the mixed diesel additive into high-pressure molecular sieves for mixing;

[0030] S6, static reaction for 4-8 hours after high-pressure molecular sieve mixing;

[0031] S7, taking out the diesel additive that has completed the static reaction, and packaging it in separate bottles.

[0032] Said S1, the raw materials are calculated by mass percentage as follows: No. 200 oil component oil 30-88.5%, methanol 10-55%, composite additive 1.5-15%, vapor pressure regulator 1.5-3.5%.

[0033] Said S1, the purity of methanol is selected to be above 99.5%.

Abstract

The invention relates to the field of diesel additives in the energy industry, in particular to a preparation method of a tail gas cleaning agent. The method comprises the following steps: S1, selecting raw materials: 200# component oil, methanol, a composite additive and a vapor pressure regulator; S2, uniformly mixing the vapor pressure regulator, and adding the mixture into methanol to form a blend; S3, adding the composite additive into the blend; S4, slightly stirring the blend, and injecting the blend into the 200# component oil; S5, putting the mixed diesel additive into a high-pressuremolecular sieve and mixing the mixture; and S6, mixing the high-pressure molecular sieves, and carrying out a static reaction for 4-8 hours. The preparation method effectively solves the technical problems of power reduction, high oil consumption, corrosivity, swelling property, difficulty in cold start, high-temperature air resistance and the like when the content of low-nitrogen diesel oil is 10-55%. The product can be directly used by an automobile, and an engine does not need to be changed; the product can also be mixed with biodiesel and common diesel for use or used in a cross exchangemanner.

Description

technical field [0001] The invention relates to the field of diesel oil additives in the energy industry, in particular to a preparation method of an exhaust gas cleaning agent. Background technique [0002] Diesel light petroleum product is a complex hydrocarbon mixture with a carbon number of about 10-22) and is a compression ignition engine fuel. The most important use of diesel is diesel engines for vehicles and ships. Compared with gasoline, diesel With high energy density and low fuel consumption rate, diesel has low energy consumption, so some small cars and even high-performance cars also switch to diesel. [0003] Compared with gasoline, diesel oil contains more impurities, and it is more likely to produce smoke and dust when it burns, causing air pollution. The soot produced after diesel combustion may cause cancer. Therefore, in recent years, diesel oil burning in Western European countries, including cars The machine must be equipped with a dust filter before it...
