Problems solved by technology

[0002] Diesel water mixing technology has been studied for nearly half a century at home and abroad, such as Chinese patents 87106204 and 94104514.5. These schemes introduce a variety of emulsifiers for diesel water and the application of water-mixed diesel, but these emulsifiers mostly use expensive chemical raw materials , the preparation process is complicated and the cost is high
The current water-mixed emulsified diesel has many problems such as miscibility, general use, transportation, storage, and inability to withstand destructive tests.
The stability of many water-mixed emulsified diesel oil is not ideal, oil and water are easy to separate, and the storage period is short
Although some water-mixed diesel oil can be stored for one year without delamination, it can no longer be miscible with flammable solvents such as raw diesel oil, and its application is greatly restricted.

Embodiment 1

[0014] Example 1: The weight percentages of composite fuel agent and diesel oil in the finished synthetic diesel are 50% and 50% respectively. Wherein based on the total weight of the composite fuel agent, the components of the composite fuel agent are: 20% of water, 20% of benzene, 10% of methanol, 25% of turpentine, 5% of isopropanol, 5% of fatty acid, 8% of dispersant, and 5% of catalyst %, sodium hydroxide 2%.

[0015] The preparation process is as follows: add the above 20% water, 20% benzene, 10% methanol, 25% turpentine, 5% isopropanol, 5% fatty acid and 5% catalyst into the reactor, stir and mix , heated to 60-70°C under normal pressure to react for 1-2 hours; then add 8% dispersant and 2% sodium hydroxide, stir and mix evenly to obtain a composite fuel agent.

[0016] The finished synthetic diesel is obtained by stirring and mixing the above-mentioned composite fuel agent and 50% diesel oil accounting for 50% of the total weight ratio of the synthetic diesel.

Embodiment 2

[0018] Example 2: The weight percentages of composite fuel agent and diesel oil in the finished synthetic diesel are 60% and 40% respectively. The components of the composite fuel agent are: 30% water, 10% benzene, 10% methanol, 20% turpentine, 6% isopropanol, 5% fatty acid, 10% dispersant, 5% catalyst, and 4% ethylenediamine. The preparation process is the same as in Example 1.

Embodiment 3

[0019] Example 3: The weight percentages of composite fuel agent and diesel oil in the finished synthetic diesel are 40% and 60% respectively. Wherein the components of the composite fuel agent are: 10% of water, 15% of benzene, 15% of methanol, 30% of turpentine, 8% of isopropanol, 6% of fatty acid, 8% of dispersant, 6% of catalyst and 2% of sodium hydroxide. The preparation process is the same as in Example 1.

[0020] The dispersant in each of the above examples is DE-A-synthetic methylpolysiloxane microcolloid particle dispersant, and the catalyst is a hydrogenated carbon-carbon double bond heterogeneous catalyst.

[0021] The HHR-1 type synthetic diesel oil and the HHR-2 type synthetic diesel oil prepared by the method of the present invention meet the product quality standards through inspection by the Product Quality Supervision and Inspection Institute of Shaoyang City, Hunan Province, wherein the test results of the HHR-1 type synthetic diesel oil are shown in Table 1...

Abstract

The water adding synthetic diesel oil contains composite fuel in 40-60 wt% except diesel oil; and the composite fuel consists of water 10-30 wt%, benzene 10-30 wt%, methanol 10-20 wt%, turpentine 20-45 wt%, isopropanol 5-10 wt%, fatty acid 5-10 wt%, dispersant 8-15 wt%, catalyst 5-10 wt% and assistant 2-5 wt%. The synthetic diesel oil has simple preparation process, stable performance and no delamination in long term storage, may be mixed in any ratio with diesel oil, kerosene, solvent oil, etc. before use. The product has less change in color and transparency, and may be used widely in diesel car, diesel locomotive, ship engine, diesel oil engine for air conditioner, boiler, etc.
