Heterogeneous catalytic gas–liquid reactions are intensified when carried out in the homogeneous fluid phase by means of a supercritical cosolvent. For instance, supercritical propane is used to enhance the yield in hydrogenation of vegetable oils. Besides phase equilibrium knowledge, volumetric information is also needed to elucidate kinetic mechanisms and design continuous supercritical reactors.

Prediction of Volumetric Data in Supercritical Reactors

| Journal of Chemical & Engineering Data Verified
Pressure-intensified processes are characterized by handling mixtures whose density is highly dependent on the operating conditions. In addition, fluid behavior in this type of equipment is clearly nonideal. Therefore, the frequent assumption of ideal mixing for calculating the mixture density is inaccurate.
