S-graphite slit pore: A superior selective adsorbent for light
Separation of light hydrocarbons (C1-C3) is extremely significant since these are alternative energy resources and raw materials in the industrial process. In this work, we have examined the performance of S-graphite slit pore in selective separation of CH 4 over C 2 H 2, C 2 H 4, C 2 H 6, C3H6 and C3H8 using …

(5 points) Graphite, C, rather than cementite, | Chegg
Question: (5 points) Graphite, C, rather than cementite, Fe3C, is the stable carbon-rich phase in the Fe-C binary system. Note that in the published Fe-C diagrams, solubility lines for both are often given. For example, the compositions of γ-Fe (austenite, FCC ) in equilibrium with Fe3C cementite) and graphite ...

Diamond
The relationship between diamond and graphite is a thermodynamic and kinetic one, as can be seen in the phase diagram for carbon, above. At normal temperatures and pressures, graphite is only a few eV more stable than diamond, and the fact that diamond exists at all is due to the very large activation barrier for conversion between the two.
