        Equilibrium C+CO₂=2CO was studied with graphite at pressures <20 mm. Hg. 500°-700°; it shifts almost completely to the right at reduced pressure.  With semicoke from brown-coal briquets degasified at temperatures 50° higher, the shift was even more complete.  Additions of 5% Fe and Al oxides, Ca, Na, and K carbonates to degasified semicoke greatly increased the rate of reaction with CO₂ at atmospheric pressure, this effect increasing with the basicity of the catalyst.
