Recent Advances in the Characterization of Gaseous and Liquid Fuels by Vibrational Spectroscopy

Kiefer, Johannes - In: Energies 8 (2015) 4, pp. 3165-3197

Most commercial gaseous and liquid fuels are mixtures of multiple chemical compounds. In recent years, these mixtures became even more complicated when the suppliers started to admix biofuels into the petrochemical basic fuels. As the properties of such mixtures can vary with composition, there...
