摘      要：Decarbonization is a critical issue for peaking CO_(2) emissions of energy-intensive industries,such as the iron and steel *** decarbonization options of China’s ironmaking and steelmaking sector were discussed based on a systematic three-dimensional low-carbon analysis from the aspects of resource utilization(Y),energy utilization(Q),and energy cleanliness which is evaluated by a process general emission factor(PGEF)on all the related processes,including the current blast furnace(BF)-basic oxygen furnace(BOF)integrated process and the specific sub-processes,as well as the electric arc furnace(EAF)process,typical direct reduction(DR)process,and smelting reduction(SR)*** study indicates that the three-dimensional aspects,particularly the energy structure,should be comprehensively considered to quantitatively evaluate the decarbonization road map based on novel technologies or *** scrap utilization(improvement of Y)and the substitution of carbon-based energy(improvement of PGEF)in particular is *** terms of process scale,promoting the development of the scrap-based EAF or DR-EAF process is highly encouraged because of their lower *** three-dimensional method is expected to extend to other processes or industries,such as the cement production and thermal electricity generation industries.
