| 摘要: |
The Fischer-Tropsch synthesis kinetic rates were studied by discussing the hydrogenation steps of the
favored hydrogen-assistedCOdissociation mechanism and the surface site balance over an industrial ironbased
catalyst. Their mathematical expressions are the two proposed models -rFT=(kFTPCOPH2
R)/
(kCOPCO t Pi=1
i xi) and -rFT = (kFTPCOPH2
R)/((kCOPCO t Pi=1
i xi)2) in the literature. Unresolved
relationships and differences between the two models are addressed here and analyzed specifically. When
the significance of each of the terms in the two rival models is critically evaluated, both surface site balances
of the two could be simplified to two involved terms: an adsorbed CO term and a vacant site term.
Although the two models could hardly be distinguished from each other at the typical range of
experimental conditions, further theoretical analyses and extrapolated experimental data favor the latter
[its simplified form is-rFT=(kFTPCOPH2
0.5)/((1tkCOPCO)2)]. These studies are helpful to understand the
CO activation processes, and some contradictory conclusions and experimental phenomena in the
literature can be explained consistently and reasonably. |
