ORNL researchers use old tires and UCO to produce biofuel

ORNL researchers use old tires and UCO to produce biofuel

August 2, 2017 |

In Tennessee, using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory-led research team has developed a simple method to convert used cooking oil into biofuel. The team’s approach combines modified, recovered carbon with sulfuric acids, which is then mixed with free fatty acids in household vegetable oil to […]

ORNL researchers discover new class of porous membranes boosting biofuel production efficiencies

July 25, 2017 |

In Tennessee, researchers at Oak Ridge National Laboratory set out to determine what could increase production speeds and improve the quality of biofuels and bioproducts. What they discovered is a new class of porous membranes—a high performance architecture surface-selective (HIPAS) membrane technology. Supported by the U.S. Department of Energy’s Bioenergy Technologies Office, this new class […]

ORNL using microbial process to produce hydrogen from biofuel processing wastewater

ORNL using microbial process to produce hydrogen from biofuel processing wastewater

May 10, 2017 |

In Tennessee, “electrical” bacteria are the key ingredient in a new process developed by the Department of Energy’s Oak Ridge National Laboratory that recycles wastewater from biofuel production to generate hydrogen. The hydrogen can then be used to convert bio-oil into higher grade liquid fuels such as gasoline or diesel. The team’s lab-scale demonstration can […]

ORNL researchers develops method to produce ethanol from CO2

October 13, 2016 |

In Tennessee, in a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanofabrication and catalysis science, was serendipitous. The team used a […]
