The integrated system of
smelting reduction ironmaking-
gasoline synthesis-electric- ity generation, in which the
coal gas produced in the ironmaking module is first cleaned and then used as the fuel for the
electricity generation module or raw material of the gasoline synthesis module, can resolve the problem of utilization of tail gas in the smelting reduction
Ironmaking and the large investment of gasification in the integrated gasification combined cycle and gaso- line
Synthesis. Taking efficiency, scale and product structure into consideration, the processes of the two-stage
Smelting reduction ironmaking-combined cycle electricity generation with coal gas, the two-stage smelting reduction ironmaking-steam cycle electricity generation with coal gas, the one-stage smelting reduction ironmaking-combined cycle electricity generation with coal gas, and the one-stage smelting reduction ironmaking-gasoline synthesis with coal gas- steam cycle electricity generation with tail gas are techno-economically feasible and have the promise of being industrialized.
