FASTER, PLEASE: Material That Sorts Molecules by Shape Could Lower the Price of Gas. “Refiners typically use a material that can sort molecules by size during a key step in the refining process. To achieve a desired octane rating, this step has to be supplemented with energy-intensive distillation steps, or by the use of additives. The new material, which sorts molecules by shape rather than by size, can better differentiate between different types of hydrocarbon molecules, eliminating the distillation steps and the need for octane-enhancing additives.”
