A kind of environment-friendly biological liquid fuel and preparation method thereof

Abstract

The invention discloses environment-friendly biology liquid fuel and a preparation method of the environment-friendly biology liquid fuel. The environment-friendly biology liquid fuel is composed of, by weight, 55% to 75% of animal and vegetable oil, 15% to 20% of carbon 5, 10% to 12% of methylal, 5% to 10% of fatty acid methyl ester, 0.5% to 3.0% of triethylamine, 0.1% to 2.0% of smell masking agents and 0.05% to 1.5% of hydrazine. The preparation method of the environment-friendly biology liquid fuel includes the steps of firstly, taking the animal and vegetable oil, the methylal and the fatty acid methyl ester according to the mass ratio and fully mixing the animal and vegetable oil, the methylal and the fatty acid methyl ester; secondly, weighing the carbon 5 and the hydrazine according to the mass ratio and fully mixing the carbon 5 with the hydrazine; thirdly, mixing the mixed liquor obtained in the first step with the mixed liquor obtained in the second step; fourthly, sequentially adding the triethylamine and the smell masking agents according to the mass ratio and completing the preparation after the mixture is fully stirred and mixed. The key indicators of the product are up to the national standard for light diesel oil, and therefore the environment-friendly biology liquid fuel can not only be used as boiler fuel, but also be used as power fuel.

Description

technical field [0001] The invention belongs to the technical field of renewable energy. Background technique [0002] Since the outbreak of the oil crisis in the 1970s, the supply of oil has become more and more tense, and the price of oil has repeatedly hit new highs. At the end of 2007, it even broke through the mark of 100 US dollars per barrel. It is estimated that by 2030, the world's oil demand will reach 117.6 million barrels per day. The extra demand of 31.7 million barrels per day is equivalent to the daily oil production of three Saudi Arabias. From the perspective of my country's situation, with the rapid development of the national economy in recent years, my country's demand for oil resources continues to grow. Even if the consumption growth rate is relatively slow, the oil supply gap in 2010 and 2020 will be 1.5× respectively. 10 8 t and 2.5×10 8 t. At that time, my country's dependence on foreign oil will reach 45% and 54%, respectively, and oil security w...

Problems solved by technology

Domestic biodiesel production technology mostly adopts chemical method, which requires large investment and slow results. The production process involves high temperature and high pressure. The production method generally uses sulfuric acid, caustic soda, etc. as catalysts. Waste water is discharged during the production process, which will cause secondary pollution to the environment.

Moreover, the biodiesel produced by chemical methods has a high density and viscosity, and cannot be directly used in motor vehicles.
