Researchers from Singapore and China have developed a cheap and green catalytic system for turning fatty acids into fuel that doesn’t require hydrogen or a solvent.

Hydrocarbon biofuels made from waste fats and oils, such as leftover cooking oil could help reduce our dependence on fossil fuels. Traditionally, these biofuels are synthesised by transesterifying lipids under harsh alkaline conditions; in addition to generating waste solvent, this technique does not remove enough oxygen, so the products are incompatible with diesel engines. The process also doesn’t work with fatty acids as they become soapy and deactivate the catalyst. Read the full article in Chemistry World»
