In this paper we have tried to evaluate adsorption parameters of petroleum resins. Near infrared (NIR) spectroscopy is applied for resins bulk concentration evaluation during adsorption process. NIR experimental scheme and parameters are provided. NIR spectra range of 9000–13,000 cm −1 is chosen. Quartz sand (0.2–0.8 mm fraction) is used as adsorbent; benzene is used as solvent. Different...
Vapour pressure measurements are used to evaluate the enthalpy of vaporization of ethanol–gasoline mixtures. Partial molar values are also derived. The dispersed structure of ethanol–gasoline fuel is studied for the first time using the method of correlation spectroscopy of scattered light. A large range of dispersed particle sizes in different alcohol–gasoline systems is found. The dependence of...
