摘　　要：碳酸盐矿物高温炼制过程高碳排和高能耗是建材、钢铁、有色冶金等传统工业发展面临的巨大挑战,碳酸盐催化加氢转化技术通过将金属氧化物的生产过程与碳资源的高附加值转化过程耦合,有望从生产源头颠覆传统碳酸盐热分解必产二氧化碳的途径。在该过程中,利用供氢分子(如氢气、低碳烷烃、液态有机富含氢物质等)直接将碳酸盐矿物中的碳物种原位转化为高值含碳化学品,从而有望大幅降低减排成本,有望成为基于碳酸盐矿物为原料的高碳排工业“碳中和”创新技术。本文以碳酸盐催化加氢转化技术制备不同产品为出发点,从过程特点、反应机理、催化剂设计和关键技术瓶颈等方面进行了综述,分析了碳酸盐加氢转化技术制备不同产品的研究现状和现存问题;结合近期关于碳酸盐催化加氢的最新研究进展,提出了基于碳酸盐矿物原料加氢转化在建材、钢铁、耐材等重排放工业过程碳减排的应用展望,为实现CO_(2)的高效转化和减排增效提供了思路。Intensive carbon emissions and energy consumptions are the technical bottleneck for sustainable developments of traditional industries,such as the cement,steel and metallurgy,which are mainly caused by the thermal decomposition of various carbonate minerals.The technology of hydrogen-driven carbonate catalytic reduction integrates metal oxide production and high-value-added conversion of carbon resources processes to overturn the inevitable CO_(2) emission in conventional thermal decomposition pathway.In this process,the resource of hydrogen can be widely referred to various hydrogen donors(e.g.,H_(2),alkane or other substances containing hydrogen),and the high-value-added products can be C1-products or C2+hydrocarbon,thus significantly reducing the overall costs of the reduction of carbon emissions.Furthermore,the novel technology was expected to provide technical supports for the goal of carbon neutrality in intensive-carbon-emission industrial sectors using carbonate minerals as raw materials.This review presented the developments and progresses of the carbonate hydrogenation technology.Along with the clue of various value-added products,the characteristics of processes,reaction mechanisms,catalysts design and the key bottlenecks of the technologies were introduced,respectively.Based on the analysis of state-of-the-art works of catalytic carbonate hydrogenation,the challenges as well as the potential applications of the technologies in these energy-intensive industries with carbonate minerals as raw materials were proposed,which provided promising new pathways for carbon neutrality.
