The reduction of cost in the process of iron manufacture is of permanent interest in steel-making industry. An important part of the overall cost in the process of iron manufacture is the cost of production of metallurgical coke. This problem is solved by finding a new technologies of iron production (COREX) or optimization of current ways of iron production. Therefore we have adopted the metho...

OBJECTIVE Increased consumption of sugar-sweetened beverages has contributed to rising obesity levels. Under Canadian law, calories for pre-packaged foods and beverages are presented by serving size; however, serving sizes differ across products and even for the same product in different containers. This study examined consumer understanding of calorie amounts for government nutrition labels an...

Catalytic transformation of 1,2,4-trimethyl benzene has been investigated over two different USY zeolite based catalysts in a novel riser simulator at different operating conditions. FCC-SY catalyst has low acidity and FCC-CY contains high acidity. The effect of reaction conditions on the variation of isomerization to disproportionation products ratio (I/D), distribution of trimethylbenzene (TM...

Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash am...

In this paper, an integrated coke dry quenching combined gasification system using coke oven gas and steam to quench the incandescent coke is proposed. The distinct advantages of the system include energy conservation, pollution reduction, coke quality improvement and full use of resources. Based on the minimization of the Gibbs free energy, the flow rate and composition of the syngas are predi...

Objectives are to investigate the effects of benzo[a]pyrene (B[a]P) on the autonomic nervous system of coke oven workers. One hundred eighty-four coke oven workers were divided into 3 groups according to their working sites (coke oven bottom group, coke oven side group and coke oven top group), and 93 referents were recruited. B[a]P monitored by air sampling pumps as well as urinary 1-hydroxypy...

In recent years, although the China government has carried out some serious investigation and effort to shut down the indigenous coke-production, it has not achieved effective control. The main image TM754 (red, green, blue) false color composite of Shanxi province in northern China was chosen as the study area in this paper. The indigenous coke-production sites are regions which appear red and...

The danger excessive coking pressure poses to the integrity and longevity of coke ovens has been recognized for many years [1-7]. During carbonisation in a coke oven fissures in the coke are generated due to stresses that arise from the differential contraction rates in adjacent layers of coke, which are at different temperatures [8]. Typically they are longitudinal, i.e. perpendicular to the o...

Coke oven, which is a large industrial furnace, is complex in structure. A two-dimensional structure diagram can hardly help one observe the inner structure of a coke oven or master its working principle comprehensively. In order to solve this problem, a complete 3D digital model of a coke oven is generated by assembling the three-dimensional models of coke oven components created with SketchUp...
