Abstract:
It is the key technology of coke oven gas utilization to get rid of the influence of the impurities of coke oven gas. The thermodynamic laws of reforming of coke oven gas were studied by thermodynamic calculation in this paper. The factors like temperature、system pressure、iron monoxide and water which impact the change law of self-reforming of coke oven gas was researched via the heat balance equation and material balance. The results show that higher temperature, lower system pressure and an appropriate reducing atmosphere is working for coke oven gas auto-reforming. The coke oven gas auto-reforming accomplished when the temperature increased to 1173K and the system pressure was 2 atm. Carbon separation has happened when the methane content increased to 28% or lower iron monoxide content. The concentration of water had no effect on coke oven gas auto-reforming.
