Abstract: Molecular-mass distribution curves of native nanoasphaltenes in the form of fractograms for a significant sample of crude oils have been obtained using the thermal field-flow fractionation of asphaltenes, and a multidimensional analysis of…
Coalbed gas (CBG) is a typical self-generated and self-stored gas and is one of the most ideal materials for studying the geological-geochemical models of natural gas and its source rock. However, studies show that CBG is usually a mixed gas…
Rheological measurements of polyethylene solutions in a novel nontoxic solvent were used to determine the Mark-Houwink parameters for PE of widely different molecular weights to assess the viscosity average molar mass for PE of several millions of…
