8.3 STRUCTURAL PROPERTIES The CO2 radial distribution functions g(r) were computed from system snapshots generated in constant-NVT simulations. We calculated the g(r) both from molecular dynamics and Monte Carlo, the results we present here come from molecular dynamics simulations which both of the results were almost identical. The carbon-carbon radial distribution functions, reflecting the distributions of molecular centres of mass, over the densities ranging from 60.49 kg/m3 to 712.91 kg/m3 (critical density of CO2 is 468 kg/m3) is shown in the Figure 8-4. The radial distribution function g(r) has a value of zero for r → 0, because the coincidence of molecules is not allowed by repulsion. At the lowest density considered, gc-c (r) is clearly gas like, but with increasing bulk density, a smooth transition is made to a distinctly liquid like form (Clifford, 1999). The peak height decreases with increasing density and a second solvation shell appears. The Figure 8-3, shows the location of the first and the second solvation shell for a typical liquid, the later the g(r) becomes equal to unity, the later the system becomes uncorrelated. The obvious change obtained upon increasing the density is the appearance of a clear second solvation shell as ones reaches the critical density. One also finds the RDF remains distinctly greater than unity to longer distances at the critical density than it does at the other two densities shown, a result that is consistent with the presence of macroscopic correlation in an SCF in the immediate vicinity of its critical point. The correlation length becomes maximum at the critical point which translates to large simulation boxes in order to perform simulations close to Tc and Pc but as it is obvious from the figure, the radial distribution function g(r) reaches the values of unity in the box size which means the size of the simulation box is large enough to 114PDF Image | MOLECULAR SIMULATION STUDIES IN THE SUPERCRITICAL REGION

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
