How to distinguish between biodiesel and diesel 0,
In addition to the current Chinese soybean, rapeseed and other raw materials are imported from abroad, some high oil content, low cost and easy to grow plants to supplement existing oil crops. Hongkong is currently studying the introduction of B5 bio diesel, the restaurant waste oil as raw material production, insufficient raw materials by imported canola oil, and the 95% and 5% bio diesel ULSD mixed use, provides a "green way" in Hong Kong as a waste oil, reduce exhaust emission of diesel vehicle. But this effort also met Hong Kong Automobile Chamber of Commerce and some oil companies oppose, progress is not smooth.
In 80s, the United States, Japan and the European Union in many countries in the research and production of bio diesel has achieved considerable success. The United States established many large "Diesel" forest farms, planting high oil energy plants, to provide raw materials for production of bio diesel. The country for the scale production of Bio diesel is the main raw material of Soybean (the United States), rapeseed (EEC) and palm oil (Southeast Asian countries). Some research institutions also use cinder, wood, corn stalk, edible oil and other waste producing bio diesel.
Bio diesel is also called fatty acid methyl ester, mainly for plant fruit, seeds, plant duct milk, animal fat, waste edible oil as raw material, and alcohols (methanol, ethanol) obtained by esterification reaction. Make biodiesel has many advantages, such as wide sources of raw materials, can use all kinds of animal and vegetable oil as raw material; the use of bio diesel do not need any modification or replacement parts for existing diesel engines; compared with diesel, biodiesel storage, transport and use are more secure, it does not corrode the container, is non flammable; after chemical deployment, the calorific value of up to 100% diesel or more; and belongs to renewable resources, reduce the pollution of the environment on earth.
