The Basic Research Of Physical Chemistry Aspectsabout Carbon Iron Composite Made Of Shenfu-â…¢

Since the1950s, lots of CO2emissions caused by the industrial revolutionhad made extreme weather events and exacerbate water shortages in northernand drought in southern happen frequently. These environmental changes hadserious effect on agriculture and industry. CO2emissions of steel industry inChina occupies15%of the national total emissions. The ironmaking in blastfurnace accounts for about70%of the total CO2emission in steelindustry. Therefore, it is important to use less carbon in ironmaking forreducing CO2emissions of steel industry. Crude steel production increasesrapidly in our country realizing the new industrialization process. It causesresources and energy crisis. Above of those leaded to the profit space reduce. Sothe development the technology of poor quality coal-low-grade iron and expanding the range of raw fuel used in blast furnace ironmaking are the keyto enhance steel enterprises competitiveness.For this purpose, the study is based on the blast furnace metallurgicalprinciples and the analysis dynamic cutting-edge research in domestic andforeign. The non-coking coal and iron ore are crushed and mixed, after they arethermoformed and coked, C-O-Fe contact distance become shorter and CICgasification reaction is easer to occoure at low temperature. Fe catalyst andlower CIC gasification thermodynamics characteristics can reduce the top gasand lumpish temperature in the blast furnace, reducing coke ratio and CO2emissions. Through experimental research, theoretical analysis and simulation,investigate the effect of AMP content on CIC made of Shenfu-IIIgasification reaction starting temperaturethe, coke rate and CO2emissions inblast furnace. Those can provide basic research data for solving thecontradiction between iron resources and the environment. The experimentalresults are given as follows:(1) The compressive strength of ferro/coke and CIC made of Shenfu-IIIcoal and AMP improved with the increase of AMP contents. Themaximum value respectively were48.97kN/p,5.66kN/p.(2) Coal-iron is mainly composed of C, ash, Fe2O3and other phases. CIC ismainly composed of many shapes of C, white Fe particles (0.05~1μm,attachedto the surface of the porous C) and0.5~20μm pores and other composition;and C contact with Fe atom closely. (3) Fe atoms and the number and size of pores(0.5~20μm) in CICincreased with the increase of AMP content.(4) The starting temperatures of the gasification reaction dropped from936.5℃to876.3℃and the activation energy dropped from206.82kJ·mol-1to196.53kJ·mol-1with increase ofAMP content.(5) With the calorific value of coal increasing, gasification reaction startingtemperatures dropps and the reduction value of CIC increases. CIC made ofShenfu-III is not appropriate for being used as high reactivity of coke in the blastfurnace.
