A profitable production of coproduits: To produce Diester is to produce oil cakes and glycerin. These oil cakes are used in animal feeds, they constitute the 2nd most important food class after cereals. Indeed, they constitute the independent source of proteins in animal feeds. They also contain cellulose, which is digestible only by the ruminants. As for glycerin, it is used in the drug company, cosmetic and

The stake lies in the capacity to use new technologies to transform this biomass while carburizing. With this intention, two ways were installation within the framework of the Research National plan on Bioénergies (PNRB):
The thermochemical way: the cellulose and lignin lignocellulose, formed is heated at a temperature of 800°C (gasification). The produced gas called gas of synthesis can be then transfor
The European standards put the car manufacturers in the obligation to find solutions technological so that the engines less and less reject carbonic gas in the atmosphere. At the present time, the majority of the manufacturers develop and market vehicles allowing the bicarburation gasoline/Superéthanol, one calls these vehicles of Flex Fuel. They made their appearance in the European Union in 2003 (Sweden being pionnière). The ethanol has corrosive properties more significant than the gasoline, the feeding system while carburizing must be reinforced, just like certain internal elements with the engine which undergo stronger constraints (valves).
The ethanol having a different output, the times of injection managed by electronics must be modified.
