Biofuels

Biofuels are fuels produced from hydrocarbon-rich living organisms (biomass) — such as plants or microalgae — by thermal, chemical or biochemical conversion processes. As with fuels, biofuels such as biodiesel, biogas and syngas are combusted to generate energy.

    A significant portion of the energy required to electrochemically reduce CO2 to fuels and chemicals is typically consumed by the accompanying oxygen evolution reaction. Now, researchers show that alternative oxidative reactions using biodiesel-waste could improve the economics and emission profiles of this process.

    Biofuels became controversial for compromising food production. Forest residue conversion to jet fuel is a second-generation biofuel that doesn’t compete with food. However, it has unexpected implications across the Sustainable Development Goals.

    Combining biofuel synthesis with petrorefinery operations may provide efficiency benefits, but procedures to do so are not yet well-established. Now, researchers describe a two-phase catalytic scheme for production of 10% bio-enriched gasoline by directly using petroleum fractions in the catalytic processing of (hemi)cellulose.
