The molecular weight, density, and solubility parameter of the crude oil medium are inputs to regular solution based models for asphaltene precipitation. For native oils, these properties can be determined from a SARA (saturate, aromatic, resin, asph

Asphaltenes self-associate and their molecular weight, density, and solubility parameter distributions are factors in asphaltene precipitation. Thermo- and hydrocracking alter these distributions and these changes must be accounted for when modeling

Densities and refractive indices were measured for native crude oils, distillation cuts, and thermo- and hydrocracked oils at 20 °C and for some samples up to 60 °C, all at atmospheric pressure. These data as well as pure component and crude oil da

A correlation was developed to predict the density of mixtures of heavy oil (and other petroleum liquids) and hydrocarbon solvents when the densities of each fluid in the mixture are available. Densities at atmospheric pressure and 293 K were measure

Blending crude oils or crude oils and condensates of different origin may give rise to deposit related problems due to incompatibility. Although the problem has been recognized, there are as yet no standard methods for the determination and quantific

Economic pressures on the refining industry are forcing many refiners to look at low price, high value crudes to improve margins. Some of these crudes are discounted because of perceived fouling or corrosion problems. A new strategy has been develope

Crude oils, and the residual fractions thereof, vary widely in many relevant properties. Thus, a detailed characterization of a single residue stream or even a number of residue streams from one region may not be very relevant in a different part of

Stepwise switches from a 12 CO H 2 to a 13 CO H 2 feed and vice versa have been utilized to obtain transient kinetic information without disturbing the steady-state catalysis. In the context of methanation and Fischer-Tropsch catalysis it emerges tha

Addition of manganese and molybdenum compounds to silica-supported rhodium catalysts results in a significant increase in their activity for synthesis gas conversion. The location of these promoter elements and their role in the CO H 2 reaction have
