Physical-Chemical Properties of Jet Fuel Blends with Biofuels Derived from Waste

Chemical Engineering Transactions
Jet fuel blends with bio-based compounds are an alternative for reducing carbon emissions. The properties of the bio-jet fuel blends can be changed by varying the ratio of bio-jet fuel to Jet A-1 fuel.
