乙烯可取代乙醇制作某些原材料

Ethanol（乙醇） from corn and other plants could become the sustainable, raw material for a huge variety of products, from plastic packaging to detergents1（洗涤剂） to synthetic2 rubber, that are currently petroleum3-based. This was the conclusion of an article published in the ACS journal Industrial & Engineering Chemistry Research. Yingzhe Yu and colleagues point out that a chemical called ethylene（乙烯）, now produced from petroleum, is one of the most important raw materials for everyday products. Ethylene is used to make hundreds of products, including polyethylene（聚乙烯）, the world's most widely used plastic. Scientists have been seeking sustainable alternatives to petroleum for making ethylene, and Yu's team reviewed progress in the field.
 
They found that one particular device has the potential to make a highly pure ethylene product from ethanol with high efficiency and low cost. The device, called a fluidized bed reactor4, works by suspending the chemicals needed to make ethylene inside the walls of a chamber5. Newly produced ethylene exits through a pipe, while the rest of the material remains6 to continue production. Yu's team discusses progress toward commercial use of such devices, noting that there would be "great significance" for promoting economic development.
