Vapor-liquid equilibria (VLE) for toluene + heavy oil, n-decane + heavy oil and cis/trans-decalin + heavy oil systems were measured by a flow type apparatus at temperatures ranging from 573 to 643 K. The experimental data obtained in this work were correlated by Peng-Robinson equation of state with van der Waals one fluid model. The critical parameters and acentric factors were estimated using the Marrero-Gani and Constsantinou-Gani group contribution methods. The correlation results could represented the VLE data well by applying Gao method to the fitting of the binary interaction parameters (k_<ij>).
