In order to reduce greenhouse gas (GHG) emissions, biocoke modified with different additives was used replace part of the petroleum coke. Previously, a number researchers attempted manufacture anodes using biocoke. However, majority these efforts were unsuccessful because quality deteriorated this replacement. The deterioration due weak interactions between pitch and compared those study, chemi...

High-chromium vanadium and titanium magnetite (HCVTM) sinter has poor properties. The coke ratio has an important effect on the behavior of HCVTM sintering as it affects the mineral phases in the high-chromium vanadium and titanium sinter (HCVTS) via changing the sintering temperature and atmosphere. In this work, the sintering behavior of HCVTM mixed with varying coke ratios was investigated t...

Polycyclic aromatic hydrocarbons (PAHs) result from the incomplete combustion of natural or synthetic organic materials. The working environment at a coke plant can negatively affect the employed workers who were exposed to coke oven emissions containing PAHs, which formed and released into the environment by the process of pyrolysis of coke. This study aims to analyze the relationship between ...

Walker, D. D., Archibald, R. M., and Attfield, M. D. (1971). Brit. J. industr. Med., 28, 358-363. Bronchitis in men employed in the coke industry. An epidemiological survey to determine the prevalence of bronchitis in men employed at two of the National Coal Board's coking plants is described. Eight hundred and eighty-one men (91 %) of the total working population were examined. A strong associ...

OBJECTIVE To present the protocol and the early results of a urothelial carcinoma (UC) screening analysis performed in a risk population of coke workers. METHODS Between June 2006 and October 2008, 171 male workers (mean age 43 years), employed in a Ligurian coke plant (Italiana Coke S.r.l) and exposed to polycyclic aromatic hydrocarbons (PAHs) for a median period of 16 years, underwent scree...

Coal classification schemes have been developed over many years from studies of the physical and chemical properties of coals as a method of dividing coals into various categories according to their behaviour during carbonisation and combustion. Although there is no universally accepted scheme, most coal classification schemes are based on two main types of parameters:a)volatile matter, and b)c...

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...

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...

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 ...

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...
