Abstract

In the context of fossil fuel sources are gradually depleted, production and use of biofuels has become a popular trend in the world. In Vietnam, the development of biofuel production and use has been implemented since 2018. However, in order for this fuel to be widely used to contribute to environmental protection, there are still many obstacles.Among the alternative energy sources currently in use (wind, solar and nuclear energy), bioenergy is an inevitable development trend, especially in agricultural countries and imported. fuel, due to its benefits: production technology is not too complicated, utilizing local raw materials, increasing agricultural economic efficiency, without changing engine structure as well as lower facilities Existing floors and competitive prices compared to gasoline.Increasing the use of biofuels is not only about protecting the environment but also contributing to the positive transformation of the lives of people in remote areas of the country.

Highlights

As we all know, the world economy has so far and can last for most of the 21st century, heavily dependent on fossil fuels, despite this resource, including crude oil, which is a very big and polluting agent, is entering the preparatory phase of exhaustion as the inevitable fate of all kinds of finite natural resources when fully exploited [1][2][3].In addition, the need to protect the living environment on earth is long-term clean as well as the need for economic development at a high speed and on a large scale, making global energy security increasingly threatened. important
Bioethanol is capable of completely replacing petroleum-derived gasoline, or it can be mixed with gasoline to produce bio-gasoline
Bio-butanol has many advantages over bioethanol, such as being dissolved in gasoline, machinery is less likely to be corroded due to its non-absorbent properties; Not soluble in water, so it is easy to distill to absolute purity; energy density is 25% higher than bioethanol, close to the energy density of gasoline made from petroleum; High octane index approximates the average octane index of gasoline (RON96), so when using, it is not necessary to convert conventional gasoline engines; There is much lower pressure than gasoline as well as bioethanol, so it is less likely to be lost due to evaporation during storage, transportation, distribution and safety when using [12]

Summary

INTRODUCTION

The world economy has so far and can last for most of the 21st century, heavily dependent on fossil fuels, despite this resource, including crude oil, which is a very big and polluting agent, is entering the preparatory phase of exhaustion as the inevitable fate of all kinds of finite natural resources when fully exploited [1][2][3]. Made from petroleum, biodiesel has many advantages in terms of environmental protection such as, low sulfur (2-11ppmS), easy to decompose by microbiology, reducing air pollution. They are more lubricant than petroleum diesel, so the engine life will be longer and the material is taken from agricultural products or waste, so it can be regenerated quickly, contributing to increase value, using redundant labor, barren land, reducing import costs in foreign currencies [19][20]. The disadvantage of biodiesel compared to petroleum diesel is that, the lower the heat, the higher the freezing point, the harder it is to use in the cold or in the winter, not the complete alternative to oil because of the supply of raw materials. difficult, abundant but not big enough to meet the demand; high costs should have a support policy of the state, production equipment and infrastructure in distribution must be newly built, the legal system to use gasoline fuel biofuel is not available or incomplete
