Biodiesel is good or not saturated fatty acid
As everyone knows, the diesel molecule is composed of about 15 of the carbon chain, the study found that the vegetable oil molecules are generally composed of 14-18 carbon chain, similar to diesel molecular carbon number. So biodiesel is a renewable oil processing plant for rapeseed production of new fuel. According to the composition of the chemical analysis, bio diesel fuel is a kind of high fat acid methane, it is not saturated by oleic acid C18 as the main component of the glycerides obtained by decomposition
The main characteristics of biodieselBiodiesel is a clean and renewable energy, with soybean and rapeseed oil crops such as oil palm oil, and Chinese pistacheThe utility model relates to a liquid fuel which is made of oil tree fruit, engineering microalgae, oil water plants, animal oil, waste cooking oil, etc.Biodiesel is a typical substitute for petroleum diesel oil, which is a typical "green energy"It is of great strategic significance to promote sustainable development, promote energy substitution, reduce environmental pressure and control urban air pollution
Two is the use of biodiesel synthesis chemical method has the following disadvantages: complex process, alcohol must be excessive, the follow-up process must have the corresponding alcohol recovery device, high energy consumption, large equipment investment; deep color, the unsaturated fatty acid in high temperature metamorphism; esterification products difficult to recovery and high cost; production process waste lye emissions.
Main disadvantage:One is using rapeseed oil as feedstock for biodiesel production costs are high, according to statistics, 75% of the cost of biodiesel preparation is the raw material cost. Therefore the use of cheap raw materials and improve the conversion to reduce the cost of biodiesel is key to the practical.
