its chemical composition and the closest fuel conversion technology is relatively mature. Currently,scarpe hogan donna, most of the aviation biofuels from oil-based raw materials are transformed from. However,barbour france, the prices of such raw materials more expensive,hollister france, about 1-25 times the current petrochemical CAO. Coupled with the loss of transformation and production costs,basket nike tn pas cher, the current aviation biofuel production costs through this oil is about 3-40 times the petrochemical CAO.The second category of sugars and starches,abercrombie outlet online, including cane sugar,hollister site officiel, corn starch,hollister e co, cassava starch and sugar industry waste, the annual output of about 10 million tons in China. Its raw material price is about 15-80% of petrochemical fuel. Starting from sugars and starches,hogan milano, including jet fuel production technology roadmap microbial fermentation and chemical conversion. Currently bio-fermentation products can only fuel the highest proportion of 10% participation mixed with fossil fuel,outlet hogan, the cost is about 3-10 times that of the latter. Chemical conversion process is still in the research stage.The third category of lignocellulose,hollister pas chere, which includes a variety of crop straw, corn cobs,chaussure tn pas cher, forestry waste wood, paper mill waste.
the annual output in China in about 700 million tons. Although the production is very large, but lignocellulose to change fuel technically have greater challenge. Currently only one based on coal liquefaction technology can be used lignocellulose conversion,doudoune pjs pas cher, but a huge upfront investment apparatus of the method, and the process is cumbersome. Cost of the product is more than 10 times the petroleum-based jet fuel. Currently, the other based on lignocellulosic conversion technologies are still in development or approval stage.2,air max pas cher femme, the characteristics of China's aviation biofuel developmentAviation biofuels expert, Dr. Wu Dongyang Boeing vice president of technology and R & D China has said that China will not be considered in order to focus on sugar and starch as a raw material to make aviation biofuel production. Because according to national conditions.
The biggest difference between general aviation biofuels and biofuels that aviation engines for curing indicators and technical parameters required aviation biofuels is relatively high,air max bw pas cher, so the corresponding fuel conversion process is more stringent. In other words,hollister outlet, aviation biofuels and fossil fuels existing aviation agreement with strict quality standards. At least in the foreseeable future, it is difficult to find other chemical alternatives.Features and development of aviation biofuelsAviation biofuels industry crucial point is to realize localization, that we should make full use of our resources to the appropriate biomass refining bio-fuel, in order to effectively reduce energy consumption and carbon aviation biofuel life cycle emissions, to achieve true sustainability.1, the main raw material of aviation biofuelsCurrently,hollister abercrombie, the main raw material in accordance with China's aviation biofuel chemical composition, can be divided into three categories. The first category of animal and plant oils,nike tn officiel, including palm oil, jatropha oil, waste animal fats,pjs doudoune, food oils and algae oil, China's annual output of about 500 tons. Animal and vegetable fats as a feedstock aviation biofuels highest energy density.
