Pyrolysis and gasification of coal at high temperatures [PDF]
, 1988 We made considerable progress towards completing the development of a thermogravimetric reactor with video microscopy imaging capabilities (TGA/VMI). The video micrOSCOPY components were designed, installed and are currently under testing. With the newly developed TGA/VNH apparatus we can directly observe macroscopic changes in the morphology of ...

GASIFICATION STUDY OF SARAWAK COALS
ASEAN Journal on Science and Technology for Development, 2017 Thermogravimetry (TG) has been applied in a preliminary investigation, to the gasification of two low rank Sarawak coals. The coal samples, about 10 mg were investigated within the temperature range 30–900°C at different heating rate of 10, 20 and 30°C min-1, under a synthetic air atmosphere for the gasification study.
