This review summarizes the advances made in the last decade in understanding the effect of phase conditions in the performance of supercritical reactors and in the control of process outputs. The study covers heterogeneo ...

This chapter deals with fundamentals of supercritical fluid extraction. Considering first the typical phase diagrams of high pressure systems. Thereafter the application of supercritical fluids to separations is illustrated ...

Advanced biofuels, when used as components in fuels, offer advantages over fossil-based hydro-carbons and conventional biofuels to realize highly efficient and clean propulsion systems. Among the several chemical routes ...

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 non-ideal. Therefore, ...

The production of first generation biofuels has increased in the last few years because of the rising price of fossil fuels and environmental policies. Biodiesel process alternatives have been proposed in order to achieve ...

This study aims to discuss some of the factors that influence the production of hydrogen via the gasification of organic matter in supercritical water. These factors have been investigated based on the reactions of organic ...

In the present work, the transesterification of non-edible oil with methanol and ethanol is studied. The reactor phase transitions are directly observed in a double windowed cylindrical reactor and the conversion to fatty ...
