The influence of selected oxides and carbonates on thermal oxidation of coke
Original language description
An influence of inorganic compounds (Fe2O3, CaCO3, ZnO, PbO and K2CO3) on the blast furnace coke thermal oxidation in the air and in the CO2 atmosphere was investigated by means of thermal analysis. A catalytic effect showed itself at the oxidation in the air, especially with PbO and K2CO3. These compounds bring the oxidation starting temperature and activation energy down and increase the reaction rate constant most distinctly. The PbO and K2CO3 actions differ in their mechanisms. K2CO3 accelerates particularly the amorphous coke fractions oxidation. In the CO2 atmosphere an important catalytic effect occurred only with K2CO3. The PbO catalytic influence is less distinct.
