摘要
无机金属碳酸盐是地球储量丰富且分布广泛的无机矿物质资源,广泛应用于建筑、冶金、化工等领域.碳酸盐热解是碳酸盐利用过程中的关键工艺环节,大量排放CO_(2).面对双碳挑战,迫切需要创制变革性技术,从源头上根本解决碳酸盐热解过程中的碳排放问题.本文重点介绍了碳酸盐加氢炼制研究进展,包括碳酸盐催化加氢还原、碳酸盐自催化加氢还原以及碳酸盐热解共热耦合其他富氢物种转化等,进一步结合本文作者团队的最新成果,提出创制碳酸盐基合成气造气耦合重排放过程源头减排原创技术,并对此技术的应用前景进行了展望.
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 via 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.
