摘要：
High pressure phase equilibria of supercritical carbon dioxide with n-alkanes, n-C-12, n-C-16, n-C-20, n-C-24, n-C-28 and n-C-36, have been measured over the temperature range of 313-367 K, and are reported in this work. Of the various equations of state investigated, it was found that the Patel Teja equation of state provided the best fit of the CO2-n-alkane systems. (C) 2002 Elsevier Science B.V.
