On April 27, according to foreign media reports, an international research collaboration marked an important step in the commercial production of biobutanol, making biobutanol an alternative to gasoline engine fuel and paving the way for away from fossil fuel. Butanol, which is 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, a gallon can support cars to travel 10% more, and ethanol can travel 30% more.
This research published in the Journal of the American Chemical Society reveals a key breakthrough in the production of biobutanol and develops a new metal organic framework (MOF) that can effectively The alcohol is separated from the fermentation broth of the fermented biomass required for fuel production.
Kyriakos Stylianou of Oregon State University said: "We are trying to use the new metal organic framework to expand the scale of the separation method. If it can scale well, it may be an important milestone towards fossil fuel-free development . "
This new metal-organic framework was completed by Stylianou and colleagues from Switzerland, China, the United Kingdom, and Spain, based on copper ions and carborane carboxylic acid ligands, called mCB-MOF-1. MOF can extract butanol from fermentation broth by adsorption, which is more efficient than distillation or any other existing method. And MOF is stable in organic solvents, hot water, acidic and alkaline aqueous solutions.
Researchers say that biofuels can enhance energy security and supply, and become an important part of the energy plan, but also help carbon emissions and respond to the climate crisis. In addition, biobutanol is better than bioethanol, including the same energy density as gasoline, and fully mixed with gasoline.
