摘要

钢渣是钢铁冶炼过程中排出的废弃物,具有产量大、温度高、化学成分复杂、稳定性差等特点。将钢渣应用于制氢和固定二氧化碳对降低能耗、获取可再生能源和固定空气中的二氧化碳具有重要意义。本文介绍了中低温制氢和固定二氧化碳用钢渣高温显热的研究进展,深入分析了不同制氢方法的反应机理和未来高效制氢的处理途径和方向,并从固定二氧化碳的理论、效果和处理模式等方面对固定二氧化碳用钢渣进行了探讨和总结。未来,钢渣制氢和固定二氧化碳的经济效益研究是重点,在利用钢渣资源的同时,实现经济效益。

Research progress of hydrogen production and CO2 fixation in molten slag cooling process

Steel slag is a waste discharged from the iron and steel smelting process, which has the characteristics of large output, high temperature, complex chemical composition and poor stability. The application of steel slag in hydrogen production and CO2 fixation is of great significance for reducing energy consumption, obtaining renewable energy and fixing CO2 in the air. In this paper, the research progress of high-temperature sensible heat of steel slag used for hydrogen production and CO2 fixation at medium and low temperature is introduced, the reaction mechanism of different hydrogen production methods and the treatment path and direction of high-efficiency hydrogen production in the future are deeply analyzed, and the steel slag used for CO2 fixation is discussed and summarized from the theory, effect and treatment mode of CO2 fixation. In the future, the research on the economic benefits of hydrogen production and CO2 fixation from steel slag is a major focus, which can achieve economic benefits while utilizing steel slag resources.
