Effect of calcium and barium on potassium-catalyzed gasification of ash-free carbon black

Gasification of carbon black, an ash-free carbon feed, was performed with K2CO3 and either CaCO3 or BaCO3 as catalysts to examine their interaction. Mixtures were prepared by low-energy ball-milling, and then gasified with CO2 at 750–850 °C in a thermogravimetric analyzer. At temperatures below 800 ...

Mixtures were prepared by low-energy ball-milling, and then gasified with CO2 at 750–850 °C in a thermogravimetric analyzer. At temperatures below 800 °C, the presence of calcium had little impact on the potassium-catalyzed gasification of carbon black. At higher temperatures, calcium promoted the activity of potassium up to ∼50% conversion through the formation of a eutectic phase that increased the diffusivity of the potassium. At higher conversions, the tendency of CaCO3 to sinter and limit diffusion of CO2 to the carbon inhibited the reaction. BaCO3 also formed a eutectic phase with K2CO3 confirming that the phase change was beneficial. In contrast to CaCO3, however, BaCO3 does not sinter at 850 °C, such that gasification was promoted to complete conversion.

Mixtures were prepared by low-energy ball-milling, and then gasified with CO2 at 750–850 °C in a thermogravimetric analyzer. At temperatures below 800 °C, the presence of calcium had little impact on the potassium-catalyzed gasification of carbon black. At higher temperatures, calcium promoted the activity of potassium up to ∼50% conversion through the formation of a eutectic phase that increased the diffusivity of the potassium. At higher conversions, the tendency of CaCO3 to sinter and limit diffusion of CO2 to the carbon inhibited the reaction. BaCO3 also formed a eutectic phase with K2CO3 confirming that the phase change was beneficial. In contrast to CaCO3, however, BaCO3 does not sinter at 850 °C, such that gasification was promoted to complete conversion.

abstract	Gasification of carbon black, an ash-free carbon feed, was performed with K2CO3 and either CaCO3 or BaCO3 as catalysts to examine their interaction. Mixtures were prepared by low-energy ball-milling, and then gasified with CO2 at 750–850 °C in a thermogravimetric analyzer. At temperatures below 800 °C, the presence of calcium had little impact on the potassium-catalyzed gasification of carbon black. At higher temperatures, calcium promoted the activity of potassium up to ∼50% conversion through the formation of a eutectic phase that increased the diffusivity of the potassium. At higher conversions, the tendency of CaCO3 to sinter and limit diffusion of CO2 to the carbon inhibited the reaction. BaCO3 also formed a eutectic phase with K2CO3 confirming that the phase change was beneficial. In contrast to CaCO3, however, BaCO3 does not sinter at 850 °C, such that gasification was promoted to complete conversion.
