The kinetic study of catalytic low-rank coal gasification under CO2 atmosphere using MVRM

In this study, we carried out a kinetic investigation and analysis of the syngas produced by low-rank coal gasification. We conducted a proximate and ultimate analysis of six types of coals in order to measure the amount of sulfur and ash. The coal was then analyzed using a thermo gravimetric analyzer (TGA) to select a suitable sample. The selected Samhwa coal sample was mixed with catalysts. Samples mixed with catalysts were used to determine the activation energy under CO2 atmosphere using the modified volume reaction model (MVRM). An analysis of the resulting syngas was performed using gas chromatography (GC). (C) 2013 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
