Abstract: Metallurgical gas, produced in the metallurgical industry, if mishandled, can lead to serious carbon emissions and air pollution,posing significant challenges for carbon neutrality in the steel industry. Metallurgical gas, especially coke oven gas, serves not only as afuel but also holds significant chemical resources in its carbon and hydrogen elements. Utilizing co-production processes to manufacture chemicals in the steel industry offers promising solutions to environmental and energy issues such as greenhouse gas emissions, resource wastage, energy consumption, and air pollution. In the catalytic carbon sequestration process, the catalytic production of methaneand low-carbon alcohols using coke oven gas has attracted considerable attention due to its advantages in process efficiency and operationalfeasibility. Firstly, the process conditions and reaction mechanisms for catalytic methane and methanol production from coke oven gas wereintroduced, along with discussions on the influence of factors such as additives and carriers on the catalyst′s resistance to coking and stability. Secondly, the importance of constructing dual active centers with high activity and stability in the design of catalysts for the production of other low-carbon alcohols from coke oven gas was emphasized, elucidating the impact mechanisms of precursor structure and additives on the modified Fischer-Tropsch synthesis catalysts and modified methanol catalysts. Regarding reaction conditions, methane conversion requires higher temperatures, while methanol production requires higher pressures. In terms of process complexity, methane conversion is the simplest, whereas formic acid production is the most complex. In terms of hydrogen consumption, formic acid production doesnot require hydrogen consumption, while methane conversion consumes the most hydrogen. Carbon sequestration co-production shouldbe carried out adaptively, considering various practical factors and product economic benefits, to continuously promote catalytic carbon reduction, driving innovation in carbon sequestration co-production technology and the development of clean energy technologies.
