Tools for Bark Biorefineries: Studies toward Improved ...

The bark of trees contains an interesting mixture of bioactive compounds, or so-called extractives. The use of ,supercritical, carbon dioxide (sc-,CO2,) eliminates both the need for organic solvents as extractants and the danger that solvent traces might compromise the purity of the extracts. Unfortunately, the complexity and natural variability of extracts’ composition render any utilization ...

A numerical model was established to investigate the dynamic oscillation characteristics of ,supercritical, carbon dioxide (sc-,CO 2,) impacting jets.The jet hydrodynamics, heat transfer, and physical properties of sc-,CO 2 fluid, were incorporated into the model. The coupling of multiple fields with large velocity and pressure gradients was achieved using a modified SIMPLE segmentation algorithm.

1/10/2011, · Instead of steam this process uses ,supercritical CO 2, (SC-,CO 2,) as a blowing agent, a nutrient carrier, and as an in-line process modifier (Alavi, Gogoi, Khan, Bowman, & Rizvi, 1999). SCFX uses ,supercritical, carbon dioxide (SC-,CO 2, ), which is a ,fluid CO 2, that has been brought above its ,super critical, point (7.29 MPa at 31 °C), as an expanding gas upon exit ( Rizvi, Mulvaney, & Sokhey, 1995 ).
