| Abstract: | Modification of present coke oven and development of different type of coking process are investigated by many institutions. In such a trend, much attentions are paid to lower the production cost by decreasing the carbonization temperature.
In this study, Medium Temperature Carbonized Coke (MTCC) or Low Temperature Carbonized Coke (LTCC) and sinter in mixed bed were served to heating-up reduction experiments. Experimental conditions were as follows: heatingup rate was 10°C/min from 200°C to 1450°C and gas composition was Ar-25.5%C0-4.5%CO2.
Coke carbonized at lower temperature has generated larger amount of H2 and had much effects on reduction. So H2 from LTCC had larger effects on reduction both directly and indirectly than MTCC.
In the temperature range from 600°C to 900°C, gasification reaction of high reactive carbon from carbon deposition reaction below 600°C increased the reduction potential of gas and promoted the reduction reaction.
In temperature range from 900°C to 1250°C, not only the reduction by generated H2 directly, but also gasification and reduction were promoted simultaneously by mutual activation phenomenon between gasification and reduction. |
