The utilization of bio-based side streams in metallurgical coke making promotes two major factors the mitigation climate impact steel industry. Circular economy as waste material from biorefinery industry is utilized a raw industry, and production fossil-based CO2 emissions. In this work, lignin hydrolysis process was used briquetted form part blend making. For experiments analyses, briquettes ...

A literature review of studies and researches has been attempted in the field of dissimilar metal welding. Dissimilar metal welds have numerous industrial applications in area of thermal power generation, chemical, petrochemical, automobile, aerospace industries and nuclear plants etc. The purpose of this paper is to review: (a) Dissimilar metal welds, their Metallurgical and Mechanical aspects...

Blast furnace (BF) is the most used equipment for production of iron in world. It charged mainly with metallurgical coke and ferrous materials. When descending inside BF, iron-bearing materials start reducing melting other burden This leads to formation so-called primary slags from which final slag formed as descend furnace. Each charge material has a unique effect on total composition BF slag....

Within the framework of the European Metrological Research Program (EMRP) IND04 MetroMetal 'Ionizing radiation metrology for the metallurgical industry', joint research carried out by 14 metrological institutions from countries within the European Union and the company ENVINET, questions concerning the determination of radioactivity in samples relevant to the metallurgical industry were resolve...

Many host factors or biomarkers are involved in the process of early DNA damage induced by occupational exposure to polycyclic aromatic hydrocarbons (PAH) as seen in coke-oven workers. This paper aimed to identify complicated causal interrelationship of various biomarkers using the path analysis. In this analysis, we included 235 subjects (166 coke-oven workers and 69 nonexposed controls) whose...

Regeneration of the coked catalyst is an important process of fluid catalytic cracking (FCC) in petroleum refining, however, this process will emit environmentally harmful gases such as nitrogen and carbon oxides. Transformation of N and C containing compounds in industrial FCC coke under thermal decomposition was investigated via TPD and TPO to examine the evolved gaseous species and TGA, NMR ...

In this study constructed wetlands (CWs) were used to remove three heavy metals (Zn, Cu and Pb). The two tested substrates were made of coke and gravel, respectively. First order dynamic model was appropriate to describe removing of Zn and Cu. The experimental results showed that first dynamic removal rate constants of Zn in CWs with coke and gravel were 0.2326 h and 0.1222 h, respectively. And...

Calcined coke is a competitive material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is exhausted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant. To help improve the energy efficiency and reduce natural gas consumpti...

Exploring the associations between genetic polymorphisms of metabolic enzymes and susceptibility to polycyclic aromatic hydrocarbon (PAH)-induced chromosomal damage is of great significance for understanding PAH carcinogenesis. Cytochrome P450, glutathione S-transferase, microsomal epoxide hydrolase, NAD(P)H:quinone oxidoreductase, and N-acetyltransferase are PAH-metabolizing enzymes. In this s...

BACKGROUND The incidence of hospital admissions for respiratory and cardiovascular diseases in areas close to operating coke works in England and Wales was investigated. METHODS A small area study using distance from source as a proxy for exposure was undertaken in subjects aged 65 or over and children under 5 years within 7.5 km of four coke works (1991 estimated populations 87 760 and 43 93...
