Coal-Based Carbon Foams. Influence of the Precursor Coal
Carbon foams were obtained from several bituminous coals with different plasticity and volatile matter content by a two-stage thermal process. The first stage, a controlled carbonisation treatment under pressure at 450-500 °C, is responsible for the final textural properties of the foam. In the second stage the carbonisation product was baked at 1100 °C. The foams produced display a macroporous texture with plasticity, volatile matter content and maceral composition of the precursor coals having an influence on the apparent density and the pore size of the resultant porous products.

| Summary: | Carbon foams were obtained from several bituminous coals with different plasticity and volatile matter content by a two-stage thermal process. The first stage, a controlled carbonisation treatment under
pressure at 450-500 °C, is responsible for the final textural properties of the foam. In the second stage the carbonisation product was baked at 1100 °C. The foams produced display a macroporous texture
with plasticity, volatile matter content and maceral composition of the precursor coals having an influence on the apparent density and the pore size of the resultant porous products. |
