Problems solved by technology

[0006] Diesel oil is mainly obtained by refining crude oil, and the source of raw materials is relatively single; the cost is high, and the combustion is incomplete, and the exhaust gas contains many harmful substances; it causes great pollution to the environment
In the prior art, diesel oil is produced by refining waste tires or plastic products, but the cetane number is low and there are many impurities, which will burn to form porous deposits during use, greatly shortening the life of the engine, and the production and processing technology is complicated
high production cost

Embodiment 1

[0024] Embodiment 1: the coal tar after denaturation catalysis, a kind of 300KG in wood tar, bamboo tar is put into reactor, and then a kind of 299KG in the aviation kerosene that weighs by proportioning, kerosene is put into reactor At the same time, add 1KG of isooctyl nitrate as a catalyst, react at a temperature of 60 degrees and a pressure of 2 atmospheres for 4 to 8 minutes; finally add diesel oil according to the proportion and stir for 5 to 6 minutes, and make a composite diesel oil that can be packed; The tank must be able to withstand 2 atmospheres of pressure. Clean diesel oil is obtained according to the production process, which is suitable for industrial and civil use.

[0025] The invention has the advantages that it can be directly used in various diesel engines. Full combustion, strong power, clean exhaust emission. The source of raw materials is abundant and the cost is low; the production process is simple, no acid, alkali and other corrosive chemical comp...

Abstract

The invention relates to a preparation method of a clean diesel. 1000 KG clean diesel comprises the following raw materials in parts by weight: 40-50 parts of one of coal tar, wood tar or bamboo tar after being catalyzed and denatured, 30-40 parts of one of aviation kerosene or kerosene, 10-40 parts of diesel oil and 0.1-0.3 parts of isooctyl nitrate; and the clean diesel is characterized by being obtained in the following steps of: first, putting one of the coal tar, wood tar or bamboo tar after being catalyzed and denatured into a reaction kettle; putting one of the aviation kerosene or kerosene which is weighed according to a mixing ratio into the reaction kettle; meanwhile, adding the isooctyl nitrate, which is used as catalyst, to the reaction kettle; reacting the mixture for 4-8 minutes at 60 DEG C under two atmospheres; and finally, adding the diesel oil to the mixture according to a mixing ratio and stirring the mixture for 5-6 minutes so as to obtain a composite diesel. Attention needs to be paid to the fire protection in the production process.

Description

technical field [0001] The invention provides a raw material method, especially a method for preparing clean diesel oil. Background technique [0002] Diesel is the fuel required for diesel engines to work. At present, less and less oil is extracted, and the price of oil is getting higher and higher [0003] At present, gasoline, diesel, and liquefied petroleum gas are all refined from petroleum and are collectively referred to as petrochemical fuels. [0004] According to the forecast of the International Energy Organization, the mining life of global petrochemical energy is 39 years for oil, 60 years for natural gas, and 211 years for coal. How short this is in the long river of human history! Oil resources that can only be formed in hundreds of thousands of years, one barrel is less than one barrel, oil reserves are gradually depleted, and oil extraction is insufficient, leading to a global oil supply shortage and a soaring oil price situation, and the oil price caused...
