On the replica symmetric Ising spin glasses,rticles are small at 93 °C. The amount of solvation can be modified by adding other substances. Increasing the resin concentration (pentane insolubles/heptane solubles), or adding small amounts of butylamine increases the amount of solvation and viscosity. On the other hand heavy cycle gas oil(HCGO)

Natural and Accelerated Ageing Of Bitumens: Effects Of Asphaltene,d in the preferential formation of asphaltenes at an early stage of ageing process. For temperatures below approximately 90°C, it has been observed that the laboratory simulations data are closely related to the changes observed in road conditions.

Sluge Formation During Heavy Oil Conversion,om several crude sources based on the elemental composition, and parameters determined by C13 NMR and proton NMR. The amount of sludge formed in laboratory tests can be correlated to three feed-stock parameters: the amount of polynuclear aromaticity in the asphaltenes, the degree of alkyl-subsitutio

The Effect Of Surfactants To The Conversion Of Coal And Coal-Derived Asphaltenes In Coal Liquefacti may be due to the increase of surface charges and double layer expansion. In the autoclave experiments, the suggested surfactant not only raises the yield of coal liquefaction but also changes the distribution of products. Under the same condition, almost twice the yield was obtained for both coal

An Improved Molecular Thermodynamic Model Of Asphaltene Equilibria,s pressures, temperatures and solvent-oil compositions. The model is coupled with Peng-Robinson equation of state for vapor-liquid equilibria calculations. The model uses an iterative Newton-Raphson scheme to obtain solution. The model has four parameters which are determined by fitting the model to
