Melt crystallization of binary mixture of fatty acids as model biofuel

Authors


Abstract

To account for both the growth of solid layer and solute distribution in melt crystallization, we proposed empirical equations involving heat and mass transfer at the solid-liquid interface between the solid layer and melt. With the aim of separating saturated fatty acid as a solid phase from binary mixture of fatty acids as model biofuel, we performed melt crystallization by employing three different species of binary melts which contained triglyceride as unsaturated fatty acid, and myristic acid, palmitic acid, or stearic acid as saturated fatty acid, respectively. As a result, we confirmed the validity of the proposed equations under the varied crystallization conditions.
