考虑到COREX熔融还原炼铁工艺中高温煤气物理余热的有效利用和富氢预还原的可行性,模拟了在某一假想碳基填充床内待改质气流通量和气体温度对改质过程的影响。模拟结果表明,在碳基填充床内进行煤气富氢改质是可行的;水消耗量随气流通量或气体温度的提高而增加,碳消耗量随气体温度的提高而增大,但随气流通量的增加而减少;改质后(?)(CO)随气流通量或气体温度的提高而减少,(?)(H_2)随气体温度的提高而增加,但随气流通量的增加则先增加后减少。
Considering the effective utilization of physical residual heat of hot gas and the feasibility of hydrogen pre-reduction in COREX smelting reduction ironmaking process, the effects of the gas flux to be reformed in a hypothetical carbon-based packed bed on the reforming process influences. The simulation results show that it is feasible to carry out hydrogen-rich gas reforming in carbon-based packed bed. The water consumption increases with the increase of gas flux or gas temperature, and the carbon consumption increases with the increase of gas temperature. However, () (CO) decreased with the increase of gas flux or gas temperature () (H 2) increased with the increase of gas temperature, but with the increase of gas flux First increase and then decrease.
