## 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
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
