Indonesia has abundant coal resources. However, some of the coal is difficult to be mined because of its location. Some are too far below the soil surface, or also called Deep Seated Coal (DSC). Underground Coal Gasification (UCG) is an alternative Clean Coal Technology that carried out gasification underground, thus it may have a potential explore DSC. The primary assessment of underground gasification may be started from a simple thermal analysis. This paper presents those assessment on the characteristics of gasification for further prospects of underground coal gasification implementation in Indonesia. The gasification experiments were carried out in a Thermogravimetric Analyser by using ten samples of coal from various locations in Indonesia. The experimental parameters include gasification media (CO2 or air) at temperature ranges from 35°C to 900°C and a heating rate of 10°C/min. The gasification media is passed at a rate of 100mL/min. Data of weight loss of sample were obtained from this experiment. From the experimental results, Arrhenius constants obtained on gasification with air are in the range 55643 to 114245min -1 with the activation energy of 46.26 to 96.98kJ/mol. Meanwhile, the gasification with CO 2 yields Arrhenius constant 15301 up to 61339min -1 and the activation energy of 12.72 to 109.71kJ/mol. Those kinetics data provide the basic information for further exploring the possibility of underground coal gasification.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Authors would like to thank the Ministry of Research, Technology and Higher Education of Republic Indonesia for fund this research entitled “Study of Indonesian Coal Characterization to Support the Underground Coal Gasification” in the first year of two.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.5095000[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
