Commercial gasification processes are usually operated at high pressure for economic considerations. However, there is very little information available on the influence of pressure on the carbonization of coal under conditions relevant to high pressure fixed bed gasifiers. This investigation involv
To monitor changes in the fissure density in the interior of coke, pieces of an industrial metallurgical coke,were examined before and after heat treatment and gasification in carbon dioxide at 1173 K, using an ultrasonic non-destructive method (PUNDIT). Seven coke pieces were heat treated to 1173 K
