Experimental Isotherms of The Supercritical Region
L Zhou and coworkers used a volumetric apparatus to measure the adsorption equilibriums of hydrogen and methane on activated carbon (Figure 2, 3). They also measure the adsorption equilibriums of nitrogen on microporous activated carbon (Figure 4) and on a mesoporous silica gel (Figure 5) for both subcritical and supercritical region. Figure 6 shows the isotherms of methane on silica gel.

Famous quotes containing the words experimental and/or region:
“If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to flames: for it can contain nothing but sophistry and illusion.”
—David Hume (1711–1776)
“The Heavens. Once an object of superstition, awe and fear. Now a vast region for growing knowledge. The distance of Venus, the atmosphere of Mars, the size of Jupiter, and the speed of Mercury. All this and more we know. But their greatest mystery the heavens have kept a secret. What sort of life, if any, inhabits these other planets? Human life, like ours? Or life extremely lower in the scale. Or dangerously higher.”
—Richard Blake, and William Cameron Menzies. Narrator, Invaders from Mars, at the opening of the movie (1953)
