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…
A series of heavy oil (HO) thermolysis experiments in the presence of 2.510.0% maltene fraction recovered from oil has been performed. It has been shown that addition of maltene fraction provides HO conversion during thermolysis and a decrease in the…
Abstract: Relationships of the distribution of petroleum biomarker hydrocarbons (biomarker HCs), namely, n-alkanes, isoprenanes, n-alkylcyclohexanes, steranes, terpanes, and n-alkylbenzenes, in the soluble fraction and in thermolysis products of the…
The thermal dissociation process of natural gas hydrate is a Stefan phase change problem with moving boundaries. Based on the conservation integral heat conduction model of the single-phase continuous hydrate control body, the paper establishes the…
We proposed a direct in situ synthesis method for iron oxide nanoparticles (NPs) along with catalytic erformance upgrading of heavy crude oil (HCO). Our method compares the upgrading of a HCO where other iron oxide nanoparticles were synthesized by a…
