Modeling and Scaling of the Viscosity of Suspensions of Asphaltene Nanoaggregates

Energies, 2017
The scaling and modeling of the viscosity of suspensions of asphaltene nanoaggregates is carried out successfully taking into consideration the solvation and clustering of nanoaggragates, and the jamming of the suspension at the glass transition volume ...

Understanding mechanisms of asphaltene adsorption from organic solvent on mica [PDF]

, 2014
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).

Aggregation of model asphaltenes – a molecular dynamics study [PDF]

, 2016
Natural asphaltenes are defined as polyaromatic compounds whose chemical composition and structure is dependent on its geological origin and production history, hence are regarded as complex molecules with aromatic cores and aliphatic tails that occur in

Modeling the separation of water‐in‐oil emulsions in continuously fed gravity settlers using millifluidic experiments

AIChE Journal, EarlyView.
Abstract Emulsion separation remains a persistent challenge in chemical and process industries due to the metastable nature of dispersed droplets. In gravity separators, the overall separation rate is governed by the formation of a densely packed zone (DPZ) of deforming and coalescing droplets that mediates between the dispersed and continuous phases ...

Isolation of Asphaltene-Degrading Bacteria from Sludge Oil

Makara Journal of Science, 2015
Sludge oil contains 30%–50% hydrocarbon fractions that comprise saturated fractions, aromatics, resins, and asphaltene. Asphaltene fraction is the most persistent fraction.

Assessing the Asphaltene Adsorption on Metal Oxide Nanoparticles [PDF]

Iranian Journal of Oil & Gas Science and Technology, 2016
The Taguchi design of experiments (DOE) approach is adopted here to evaluate the impact ofeffective factors such as nanoparticles type, nanoparticles to model solution mass ratio, asphaltenestructure, and temperature on asphaltene adsorption equilibrium.

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Chemical characterization of liquefaction products of an inertinite enriched northern Alaska coals [PDF]

, 1989
A Northern Alaskan coal rich in inertinites was further enriched by density gradient separations. The degree of condensation of the enriched coal was estimated to be low, mainly 3 ring.
