A kind of diesel oil for smokeless vehicles and its preparation method

Abstract

The invention discloses a smokeless vehicle diesel oil, which comprises the following components in parts by weight: 180 to 220 parts of aviation kerosene, 90 to 110 parts of plant oil, 245 to 265 parts of finely-processed drainage oil, 290 to 310 parts of self-made smokeless oil, 45 to 55 parts of anti-freezing and pour point reducing agent, 8 to 12 parts of upgrading agent, and 30 to 40 parts of flame retardant. The finely-processed drainage oil is prepared by the following steps: heating drainage oil, removing impurities from drainage oil, carrying out primary filtration by a filter screen, and carrying out secondary filtration through pressurization. The smokeless vehicle diesel oil is prepared by the following steps: mixing smoke oil and edible vinegar according to a weight ratio of 1000:10-15, stirring for 40 to 50 minutes at a temperature of 11 to 12 DEG C in a rotation speed of 60 to 120 r / min, allowing the system to stand still, when the precipitate has a dark-red color and the supernatant oil has a white-green color so as to obtain the self-made smokeless oil (supernatant oil); mixing kerosene, plant oil, and finely-processed drainage oil, stirring until specific gravity reaches 0.85, transferring the mixture to another container, adding self-make smokeless oil, an anti-freezing and pour point reducing agent, an upgrading agent, and a flame retardant, stirring until the specific gravity of the mixture reaches 0.85, stopping stirring, and completely transferring the mixture to an oil storage tank so as to obtain the smokeless vehicle diesel oil. The raw material costs of the smokeless vehicle diesel oil are reduced, moreover, the diesel oil is smokeless and environment-friendly, and the quality of the diesel oil meets the standards of DB11 / 239-2010.

Description

technical field [0001] The invention relates to a kind of fuel oil, in particular to a kind of diesel oil for smokeless vehicles and a preparation method thereof. Background technique [0002] At present, the degree of purification of domestic diesel oil is not up to standard, and it will produce smoke and ash powder when burned. Long-term and extensive use will cause serious pollution to the atmospheric environment and water and soil environment. In addition, the toxic substances emitted by combustion are likely to induce various diseases and complications in the elderly in winter. Due to the low immunity of children, the sulfur dioxide produced by combustion is also likely to poison children with sulfur dioxide. In order to eradicate smog and PM2.5, whether it is new energy or old energy, the raw materials must be purified during the production process, and strive to produce smoke-free or low-smoke diesel. [0003] Smokeless or less-smoke diesel oil contains 10% oxygen co...

Problems solved by technology

[0004] However, at present, the addition of standard kerosene in the preparation of smokeless or low-smoke diesel oil is relatively high, resulting in high production costs. Due to some unreasonable aspects of the formula, the prepared smokeless or low-smoke diesel oil cannot meet the national standard requirements , even if it is the National No. 5 diesel, some of its indicators still cannot fully meet the latest DB11 / 239-2010 ("Diesel Diesel for Vehicles") standards, and it is not a real smokeless diesel
