Correction to: Structural Features of CO2-Asphaltene Particles Precipitated from Vacuum Residue Using Various Organic Diluents

Measurement of Vacuum Residue and Asphaltene Fluid Properties at Process Conditions

The vacuum residue fraction of petroleum, comprising material with a normal boiling point of over 524°C, is a complex mixture of components with a wide range of molecular weight and chemical structure. The emphasis in process development and design for conversion of the vacuum residue fraction has tended to focus on the chemistry of the feed and the cracked products, and to some extent the chem...

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Understanding mechanisms of asphaltene adsorption from organic solvent on mica.

The adsorption process of asphaltene onto molecularly smooth mica surfaces from toluene solutions of various concentrations (0.01-1 wt %) was studied using a surface forces apparatus (SFA). Adsorption of asphaltenes onto mica was found to be highly dependent on adsorption time and asphaltene concentration of the solution. The adsorption of asphaltenes led to an attractive bridging force between...

Organic modification of nano-SiO2 particles in supercritical CO2

Organic modification of nano-SiO2 particles was performed with supercritical CO2 as solvent and a titanate coupling reagent NDZ-201 as the modification reagent. The surface of the nano-SiO2 particles was changed after modification by the titanate coupling reagent from hydrophilic to hydrophobic. IR and thermo-gravimetric analyses indicate that the interaction between the titanate coupling reage...
