摘要: article i nfo The catalytic effect of inorganic species, within the ash, on CO2 gasification three South African coals containing similar carbon-structural properties (elemental, structural and petrographical properties) was assessed. reactivity with a particle size between 150 250 μm determined in thermo gravimetric analyser. measured at temperatures 900 1000 °C, pressures 1 10 bar, fractions 30%. For selected coals, decreased ash content, found to be dependent composition ash. Specifically, increased calcium magnesium content alkali index.
