Low-sulfur ester-based composite fuel oil

Abstract

The invention relates to low-sulfur ester-based composite fuel oil which can be used by automobile engines, various boilers and industrial furnaces. The ester-based composite fuel oil comprises biological diesel oil, dimethyl ether and an antioxidative stabilizer, wherein the biological diesel oil accounts for 51 to 99 weight percent of the ester-based composite fuel oil, the dimethyl ether accounts for 1 to 49 weight percent of the ester-based composite fuel oil, and the antioxidative stabilizer accounts for 0.0001 to 2 weight percent of the ester-based composite fuel oil. The fuel oil replaces high-price fossil fuel resources by low-cost renewable resources, belongs to oxygen-enriched fuel, has little theoretical air quantity required by combustion and sufficient combustion, can reduce the discharge quantity of flue gas, lowers the loss of the heat value of the discharge of the flue gas, lowers the concentration of sulfur and nitrogen compounds and granular dust in the discharged flue gas greatly and is beneficial to environmental protection, energy saving and discharge reduction.

Description

technical field [0001] The invention relates to the technical field of renewable new energy fuels, in particular to a low-sulfur ester-based composite fuel oil compounded with ester-based biodiesel and dimethyl ether for automobile engines, various boilers and industrial furnaces. Background technique [0002] With the increasing world population and the continuous development of social economy, human consumption of fossil fuels represented by oil and coal is increasing rapidly. Due to the massive consumption of fossil fuels, it has caused serious pollution to the environment and led to the depletion of fossil fuels. In order to solve the relationship between energy, environment and development, it is urgent to develop renewable clean energy. [0003] Biodiesel is a renewable and clean energy, and its processing raw materials come from a wide range of sources, and it will become an ideal energy source to replace petroleum and other fossil fuels. Biodiesel, also known as fat...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the application of pure biodiesel: the viscosity is 10-20 times higher than that of ordinary diesel, and its volatility and low-temperature fluidity are not good; the flash point and ignition point are more than twice that of ordinary diesel, and it is harder to ignite than diesel. Moreover, different qualities of biodiesel have different anti-oxidation stability, and there are different degrees of corrosion on storage containers and transportation pipelines, etc.

However, due to the conversion from liquid to gas during use, air resistance will occur, and due to the low viscosity, dimethyl ether in the oil supply system is easy to leak, and it has a corrosive effect on ordinary rubber and plastics.
