Embodiment 1

[0025] Take by weight 50% of waste oil distillate; 20% of desulfurized heavy aromatics; 18% of oil deodorization distillate; 11% of C3-C5 fusel alcohols, 1% of polyacrylate, after weighing the above raw materials, mix and stir, Pump it into a container at normal temperature and pressure, pass through a static mixer, circulate for 2 hours, and filter through a 500nm filter bag to obtain this product.

Embodiment 2

[0027] Weigh 60% of waste oil distillate; 15% of desulfurized heavy aromatics; 13% of oil deodorization distillate; 11% of C3-C5 fusel alcohol, 1% of polyacrylate, the preparation method is the same as Example 1.

[0028] The sample prepared by the foregoing embodiments of the present invention is tested for performance:

[0029] Implementation 1. Take 2 kg of the above product and put it in the fuel tank of a fixed 12-hp medium-speed diesel engine, and shake the handle. At normal temperature, shake it a few times and it will start. The amount of black smoke is small. Gradually increase the throttle, no black smoke, and low noise, indicating that this product has good ignition performance and high power.

Embodiment 2

[0030] Implementation 2. Take 1000 kg of the above product and put it into a fishing boat (the oil tank has been filled with petrochemical diesel oil in advance). At normal temperature, the ignition can be started and the sailing can be accelerated. The power performance is equal to 0# diesel oil.

[0031] After using this product for two months, it was disassembled and inspected, the nozzle of the oil pump is not clogged, there is no carbon deposit, and the driving is normal.

Abstract

The invention discloses marine diesel oil which is prepared from the following components in percentage by weight: 40-70% of a waste oil distillate, 10-25% of desulfurized heavy aromatics, 15-30% of a grease deodorizer distillate, 5-15% of C3-C5 fusel and 0.5-1.2% of polyacrylate. The marine diesel oil disclosed by the invention fully utilizes part of waste resources and renewable energy sources, can alleviate exploitation and consumption of petroleum resources, and is wide in source of raw materials, low in cost and good in economical benefit. The marine diesel oil is rich in oxygen, good in combustion property, full in combustion, high in heat efficiency, few in tail gas emission pollutant and low in sulfur content, the mechanical corrosivity and discharge of sulfide are reduced, and the marine diesel oil can be widely applied to the application field of ships using petroleum diesel such as fishing vessels, transport ships and collecting ships. The marine diesel oil disclosed by the invention is good in starting performance, small in quantity of black smoke and low in noise, the nozzle is not blocked, carbon is not deposited, the operation is strong and the accelerating performance is good, so that the marine diesel oil is the reproducible marine diesel oil which can utilize waste resources and fully replace existing petroleum diesel.

Description

technical field [0001] The invention discloses a technical field of marine diesel that can replace the field of petrochemical diesel marine, and in particular relates to a marine diesel and a preparation method thereof. technical background [0002] With the lack of crude oil exploitation in the world, oil resources are becoming less and less. In the near future, the resources will be completely scarce and the price will rise. At home and abroad, the recycling of waste resources and renewable resources has been vigorously developed, and higher requirements for energy conservation and emission reduction have been put forward. However, the current price of diesel continues to rise, and the disadvantages of large exhaust emissions and high sulfur content are in need of improvement. Contents of the invention [0003] The invention aims at the deficiency of the existing diesel oil, and provides a cheap renewable resource and waste recycling, high oxygen content, low sulfur con...
