摘要: Abstract Changes in pore properties during carbonization at a constant heating rate and no external pressure were followed for bituminous subbituminous coals by porosimetry, sorption density measurements. Observations supplemented scanning electron microscopy of volatilization All exhibited similar devolatilization behaviour structure development, showing maximum micro macropore volumes around 600 °C, partial collapse after 800 °C. The micropore did not collepse the case non-caking coal. Pore volume maxima occur least 100 °C above temperature maxima. Some interpretation is provided.
