Carbonate hydrogenation refining to reduce the carbon emission from source

<p indent="0mm">White carbonate resources, also known as inorganic metal carbonates, are abundant inorganic mineral resources widely existing on earth, widely used in fields of architecture, metallurgy, chemical engineering, and so on. The thermal decomposition of carbonates is a key process during the utilization, which inevitably releases the carbon dioxide into the atmosphere. Aiming at the goals of peak carbon dioxide emissions and carbon neutrality, it is urgent to create innovative technology to reduce the carbon emission from source in the thermal decomposition of carbonates. This paper focuses on the recent research progress of the thermal composition of carbonate <italic>via</italic> hydrogenation reduction, including the catalytic reduction of carbonates with added catalysts, the self-catalysis reduction of carbonates, and the thermal decomposition of carbonates coupled with the reduction under hydrogen-rich species. Based on the latest results of the carbonate hydrogenation refining in our research group, a new technology route on the preparation of the new source syngas from carbonate hydrogenation refining is put forward. Finally, the application prospect of the carbonate hydrogenation refining is discussed as well as the research focus in this field.
