Abstract

The Amazon region has richness of oleaginous plants that have attracted attention due to its unique properties. Integrating local communities in an economic chain of valorization of fats/oils can enhance the social dimension of local oleaginous industry sustainability. Given the large diversity of raw materials and the possibility to mix them in different proportions, an experimental effort must be done to evaluate the physical properties of such feedstocks. In this context, the development of computational tools able to estimate physical properties based on rigorous thermodynamic models can orient the experimental efforts thorough the mixtures of fats and oils most promising. The evaluation of the melting curves of nine Amazonian oils and fats is done by using thermodynamic modeling of the solid-liquid equilibrium and optimization tools. The binary blends of different raw materials were also evaluated. An average absolute error of 4.5 °C was observed for the melting point and an absolute error of 3.8% was observed for the Solid Fat Content predictions over different temperatures and blends composition.

22. Beyond biofuels: economic opportunities, recent advances and challenges in property modeling for vegetable oils

Author

Abstract

Despite the greater attention given to biofuels application in the literature, there are many economic and environmental drivers to use vegetables oils (VOs) as a renewable feedstock for other applications. These drivers are discussed in the present work and the technological challenges imposed by this shift towards new VOs uses are also discussed. They are mainly associated to the reaction routes issues, the performance regarding end-user properties, experimental procedures and property prediction models. The need for more holistic approaches (life cycle analysis) is briefly discussed and the potential benefits arising from new computer-aided tools are highlighted as well.
