A Possible Way for Efficient Utilization of Coal Energy: The Combined Process of Ironmaking with Gasoline Synthesis and Electricity Generation

The integrated system of smelting reduction ironmaking—gasoline synthesis—electricity generation was simulated by computer, in which the surplus coal gas produced in ironmaking is cleaned and used as the fuel of electricity generation or raw material of gasoline synthesis. The system can settle the problem of the utilization of tail gas in the smelting reduction ironmaking and the large investment of gasification in the integrated gasification combined cycle and gasoline synthesis. Taken efficiency, scale and product structure into consideration, the process of two-stage smelting reduction ironmaking—combined cycle electricity generation with coal gas, the process of two-stage smelting reduction ironmaking—steam cycle electricity generation with coal gas, the process of one-stage smelting reduction ironmaking—combined cycle electricity generation with coal gas and the process of one-stage smelting reduction ironmaking—gasoline synthesis with coal gas—steam cycle electricity generation with tail gas may be industrialized.
