Pyrolysis continued partial oxidation

Simultaneous thermomicroscopy/thermal analysis techniques have been developed. A TG-thermomi-croscopy system has been developed for a study of the pyrolysis and combustion of coals. The microscope is combined with a video camera to continuously monitor the thermal events involved and the sample holder for microscopy is attached to the microbalance by an aluminum oxide capillary. Events such as partial fusion, swelling, and internal structural changes associated with coal can be observed microscopically and correlated directly with noted associated mass losses. The system is particularly suitable for coal analysis involving rapid heating rates and atmosphere switching.
