Kinetics of the water-gas shift reaction over Rh/Al2O3 catalysts

A Single-Event MicroKinetic model for the cobalt catalyzed Fischer-Tropsch Synthesis

“…Chemisorption enthalpies for the various surface species are calculated via the UBI-QEP method [27][28][29], which is widely used in fundamental microkinetic modeling studies [70][71][72][73][74][75][76][77]. This method relates the chemisorption enthalpy of a species to the atomic chemisorption enthalpies of H, C and O.…”

Kinetics of the high temperature water–gas shift over Fe2O3/ZrO2, Rh/ZrO2 and Rh/Fe2O3/ZrO2

“…Further, along with Rh/Fe 2 O 3 /ZrO 2 , kinetic models were developed for Fe 2 O 3 /ZrO 2 and Rh/ZrO 2 , which may provide insight in the role of rhodium in Rh/Fe 2 O 3 /ZrO 2 . There are numerous reports of kinetic studies for the WGS reaction reported in literature for Fe-Cr [8][9][10][11][12][13][14][15], Co-Mo [16,17], Cu [18][19][20][21][22][23][24][25], Pt [26,27], La-Ce-Fe [28], Rh-Fe-Cr [29], and Rh-Al [30] based catalysts. Most of the cited kinetic studies are carried out at atmospheric conditions [8-10, 15, 16, 24, 26-29, 31] while commercially the WGS is operated at 20-30 bar.…”

Water–Gas Shift on Pd/α-MnO2 and Pt/α-MnO2

“…including Au and Pt impregnated on reducible oxides such as CeO 2 and TiO 2 , have been extensively studied [9,[15][16][17][18][19]. It is generally acknowledged that surface of metal particles adsorbs CO and oxygen vacancies of reducible oxides dissociate H 2 O molecules to form OH groups [11,14].…”
