We can finally get rid of the trouble of oil. Experts develop new biofuels: cheap and not harmful to machines

The Deep Space editor, who is smart but not self-righteous, interesting but not sensationalistic, is here again to send you information! The editor of Deep Space spent a long time sorting it out and brought you this article.

On April 27, according to foreign media reports, an international research collaboration marks an important step in the commercial production of biobutanol, making biobutanol a substitute for gasoline engine fuel and a Paving the way away from fossil fuels. Butanol, more closely related to gasoline than ethanol, can be synthesized from petroleum or made from biomass.

Butanol is also a high-energy biofuel. Compared with traditional fuels, it can support a car to travel 10 more miles per gallon, and compared with ethanol, it can support 30 more miles.

This study, published in the Journal of the American Chemical Society, reveals a key breakthrough in the production of biobutanol, developing a new metal-organic framework that can effectively convert biobutanol from fuel production The desired fermentation biomass is separated from the fermentation broth.

"We are trying to use new metal-organic frameworks to scale up the separation method," said Kyriakos Stylianou of Oregon State University. "If it scales well, it could be a step toward independence from fossil fuels." An important milestone in the development of this new type of metal-organic framework was jointly completed by Stylianou and colleagues from universities in Switzerland, China, the United Kingdom and Spain, and is based on copper ions and The carborane carboxylic acid ligand is called mCB-MOF-1. MOF can extract butanol from fermentation broth through adsorption with greater efficiency than distillation or any other existing method. And MOF is stable in organic solvents, hot water, acidic and alkaline aqueous solutions.

Biofuels could enhance energy security and supply and become an important part of energy plans, as well as contribute to carbon emissions and the fight against the climate crisis, researchers say. Furthermore, biobutanol is better than bioethanol, including the same energy density as gasoline, and mixes well with gasoline.
