Low temperature gasification of carbonaceous materials by air, as catalysed by calcium

The catalytic effect of calcium during air gasification of carbonaceous materials at mild temperature is maximum when the calcium is ion exchanged on their surface. A pyrolysis or/and HNO 3 oxidation treatment performed before the cation exchange operation enables to modify the exchangeability of th...

Summary:The catalytic effect of calcium during air gasification of carbonaceous materials at mild temperature is maximum when the calcium is ion exchanged on their surface. A pyrolysis or/and HNO 3 oxidation treatment performed before the cation exchange operation enables to modify the exchangeability of the carbonaceous material and the catalytic effect of the calcium.
