Modeling Structural Morphology of Microporous Carbons by Reverse Monte Carlo

“…Activated carbons have long been used as industrial sorbents for a wide variety of commercial applications. Originally used for sugar purification, the potential of activated carbons has since been recognized and applied to such commercial uses as drinking water purification, solvent recovery, deodorization, and air purification. , Furthermore, activated carbons have been used extensively as catalyst support in chemical processing applications. − …”

Polymerization Of Olefins By Complex Metal Catalysts

“…The metal oxide catalyst systems which have been described for the polymerization of olefins consist of a reduced transition metal oxide on a support. When nickel or cobalt oxides, supported on a charcoal catalyst, are not reduced, dimers, trimers, and tetramers are produced (22,144,146,148,166). Several patents reveal that nickel oxide which is reduced on a charcoal support is an excellent catalyst for the polymerization of olefins (42-44, 54, 147).…”

“…The reactions between lithium alkyls and titanium tetrachloride are shown in equations 18 to 22. In this case tetra-TiCh + nLiR -> TiChCLiR)» ( 18) TiCh(LiR)n + LiR -a TiCl3R(LiR)" + LiCl TiClR8(LiR)" + LiR -> TiR4(LiR)" + LiCl (22) valent titanium is involved, and the alkylation steps are all heterogeneous. The gas evolved during the mixing indicates a breakdown which may involve alkyl radicals, and unless ethylene is present during this breakdown, initiation by the active titanium radical bound to the precipitated complex is lost.…”

Modelado de sólidos mesoporosos y de fenómenos de sorción de nitrógeno

“…Los carbones activados son de tipo microporoso, poseen una gran capacidad de adsorción y han sido utilizados de manera extensiva como soportes catalíticos en diversas reacciones químicas [11][12][13][14][15]. Se componen de placas irregulares formadas por arreglos hexagonales de carbono intercaladas a manera de red [16].…”

“…En los gráficos 49 se presentan los valores de R(S LL ), R(B LL ), R(S V ) y R(B V ) en función del volumen de condensado en las redes 12 . Se representan con diferente color, en función de C , cada una de las redes y los valores de los tamaños promedio se grafican en escala de tamaños relativa.…”
