Pressure and temperature effects on hydrogenation reactions were examined using coal-derived asphaltene at 390,420 and 45o"C, under 3 and 10 MPa of hydrogen partial pressure. Higher conversion was obtained at higher reaction temperatures. Benzene-insoluble material (BI) was formed at higher temperat

## Abstract This work examines the effect of various resins and dodecyl benzene sulfonic acid (DBSA) amphiphile on asphaltene precipitation from different petroleum fluids. Various resins are added to three different petroleum fluids to measure precipitation with nβpentane. Results show that the di
## A calculation procedure is proposed which allows low-angle laser light-scattering measurements to be used as a practicable method for calibration-free molecular weight determinations of soluble coal derivatives. Application of this method to coal solutions allows thermodynamic parameters for t
