The Current situation of the Development of Biofuels and Main Technical Problems

摘要

This paper provides three types of modern bio-fuels transformation approach, and the corresponding products as well as their world-wide production and application situation. The paper also analyses the advantage and disadvantage of Marine biological fuel and current challenges. Developing bio-fuels should not simply consider energy exploitation, but should concern setting up matched production system and multi-functional frameworks, highly integrating environmental, social, and economic resources, so as to achieve goal of long-term sustainable development. Because of the greenhouse gas emissions, global average temperatures rise 0.7 Degrees Celsius in the 20th century; while global energy demand will increase 60% by 2030[l]. Confronting the challenge of the global energy security and climate change and limited reserves of fossil fuels in the earth, all countries in the world aware of the importance of the development of renewable energy, therefore, as the preferred transport fuel diversity, bio-fuel development is causing concern in the countries all over the world. European Union, Brazil, the United States and China all established bio-fuels development goals, actively expand bio-fuel technology research and development to seek better non-cereal bio-fuel feedstocks. Bio-fuel development has become the hotspot of international energy exploration.
