Abstract

The kinetic study of coupled gas-iron reactions at 15600 has been carried out for the system involving liquid iron containing carbon and silicon and a gas phase consisting carbon monoxide, silicon monoxide and carbon dioxide. The coupled reactions are:

(1)   200(g) = CO2 + C

(2)   SiO (g) + CO (g) = Si ¸ CO (g)

(3)   SiO (g) + C = Si ¸ CO (g)

in which reaction (3) proceeds as written for high initial carbon contents but proceeds in the reverse direction for high initial silicon contents. The rate-limiting factors seem to be the surface chemical reactions, with rate of supply of silicon monoxide probably contributing.
