    二氧化碳利用产业发展技术路线:以宁夏为例

    Technological roadmap for the development of carbon utilization industries: A case study of Ningxia

    • 摘要: 二氧化碳资源化利用是促进循环经济发展和碳减排的关键技术,也是实现碳中和的重要途径。宁夏是全国首个开展区域碳利用产业规划研究的省份。笔者总结和提炼了宁夏在探索二氧化碳利用技术路线和产业规划方面的经验,构建了碳利用技术评价指标体系,旨在为其他地区开展碳利用产业规划提供借鉴。调研显示,多项碳利用技术已经进入中试、示范和商业化阶段,部分技术已初步具备经济效益,产业化布局时机接近成熟。在进行区域碳利用产业布局研究时,技术成熟度、产业契合度、经济效益和减排潜力是重要考虑因素。研究结果表明,二氧化碳强化采油、二氧化碳加氢制甲醇、二氧化碳合成碳酸二甲酯、二氧化碳矿化养护混凝土、钢渣固碳以及微藻固碳等技术在综合评价中表现突出,建议宁夏优先发展;二氧化碳合成异氰酸酯、电石渣和磷石膏固碳,以及二氧化碳气肥利用等技术表现良好,建议通过试点示范方式开展前沿技术探索和储备。

       

      Abstract: The utilization of carbon is the key technology to promote the development of circular economy and carbon emission reduction, and it is also one of the important ways to achieve carbon neutrality. Ningxia is the first province in China to carry out research on regional carbon utilization industry planning. This study delves into the research advancements in diverse carbon utilization technologies, formulating evaluation indicators and a comprehensive carbon utilization technology assessment system. By integrating the current state of carbon utilization in Ningxia with future industrial plans, the study identifies pivotal technologies crucial for the deployment of carbon utilization industries in the region. The results indicate that technologies such as carbon dioxide-enhanced oil recovery, carbon dioxide hydrogenation to methanol, carbon dioxide synthesis of dimethyl carbonate, carbon dioxide carbonization curing of concrete, steel slag mineralization, and cultured microalgae demonstrated outstanding performance in the comprehensive evaluation, suggesting priority development in Ningxia. Technologies such as carbon dioxide synthesis of isocyanates, calcium carbide slag and phosphorous paste mineralization, and carbon dioxide utilization as gas fertilizer showed promising results, recommending further exploration and reserve through pilot demonstrations for frontier technologies in the next steps.
