1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
Resins of Usa oil and their four fractions obtained by column chromatography have been studied. Changes in the structural parameters of the resins and the product composition for thermolysis of the fractions at temperatures of 200245 and 450495C have…
Hydrilla verticillata contains some active compounds that potential as an antioxidant, antibacterial, anticancer, antimicrobial and antitumor. One of the active compounds in Hydrilla verticillata is steroids. This research aimed to isolate, to…
N-doped TiO2/ reduced graphene oxide (N/TiO2/rGO) composite was prepared and used together with the commercial TiO2 for comparative research on photocatalytic degradation of crude oil in seawater. Five test conditions were designed including a…
Abstract: Specific features of the distribution of vanadium and nickel duringfractionation of heavy oil resins were examined using the example of heavysulfurous oils from the Permian and Carboniferous deposits of the Volga-Uralsoil and gas basin…
In this study a novel sustainable method based on supercritical fluid extraction (SFE) method was developed for simultaneous extraction and fractionation of petroleum biomarkers. We herein proposed a two-step supercritical fluid extraction method for…
