Abstract

The invention discloses low-carbon biological methanol high-proportion substitute diesel oil and its preparation method. The low-carbon biological methanol high-proportion substitute diesel oil is formed by mixing the following raw materials: 75-95 wt% of biological methanol and 5-25 wt% of national-standard diesel oil or auxiliary agent. According to the methanol synthetic diesel oil prepared by the technology, a relative reserve volume of cheap, combustible and high-proportion liquid biological methanol and other liquid combustible are added into traditional diesel oil. Substitution rate of the petroleum component is high, and energy sources can be saved. The low-carbon biological methanol high-proportion substitute diesel oil has good social and economic benefits, and also has beneficial technical effects of environmental protection, excellent power performance, no corrosion, wide application range, stable quality, simple and convenient production and the like. There is no need to change automobiles, steamships, motor vehicles and other diesel engines, and the low-carbon biological methanol high-proportion substitute diesel oil can be directly used or blended with other fuels. According to the invention, No. 0, No.-10, No.-20 and No.-30 label general methanol diesel oil can be produced, and its performance index reaches the GB / T20828-2007(BD100) standard.

Description

technical field [0001] The present invention relates to a large proportion of low-carbon bio-methanol to replace diesel oil and its preparation method; technical background [0002] The oil resources on the earth are limited, and it is predicted that the average lifespan of oil exploitation in the world is about 30 years; [0003] This pessimistic estimate makes oil more a competitive energy source in the world. In recent years, automobile emission regulations have become more and more stringent. Therefore, it is of great practical significance to find a cheap, easy-to-obtain, and less-polluting alternative fuel for automobiles; [0004] The development of environmentally friendly new energy as an alternative fuel is the need of the national energy strategy, and it is also the need of the sustainable development of my country's industry and even the entire society. Methanol diesel is such a new energy, which has certain applications in daily life, but the existing methanol ...
