The main production route for cast iron and steel is through the blast furnace. silicon content in an important indicator of thermal condition a High contents indicate increase furnace's input and, some cases, may excess coke reactor. As costs predominate iron, tighter control therefore has economic advantages. objective this article was to design artificial neural network predict hot metal, va...

Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...

Introduction FCC decant oil is the primary feedstock to delayed coker to produce needle coke, a premium carbon precursor to synthetic graphite electrodes. Mesophase development during coking, determines the graphitizability of the needle coke product. Mesophase development, in turn, depends on the molecular composition of the feedstocks [1,2]. In a commercial delayed coking unit, liquid-phase c...

Monolithic catalysts derived from in situ supported hydrotalcite-like films on Al wires display high resistance to coke formation and sintering in the dry reforming of methane due to their hierarchical porous structure, well dispersed metallic nickel species, more basic sites and strong metal-support interaction effect.

AIMS To investigate whether current occupational exposure of coke oven workers to polycyclic aromatic hydrocarbons (PAHs) results in genotoxic effects measured in peripheral blood lymphocytes and whether these biomarkers are associated with the biomarkers of exposure. METHODS Blood and urine samples were collected immediately after a shift at the end of a working week from 50 coke oven worker...

Due to the recent increase of natural gas production in the U.S., utilizing natural gas for higher-value chemicals has become imperative. Direct methane aromatization (DMA) is a promising process used to convert methane to benzene, but it is limited by low conversion of methane and rapid catalyst deactivation by coking. Past work has shown that membrane separation of the hydrogen produced in th...

In his comment on The Indiscipline of Tourism, Neil Leiper steers his argument by way of an indisciplined scenic route, treating the reader to asides about the Royal Family, the tourism industry and even a journey to Austria with the economist Khan. His many asides serve often to obscure, rather than underpin, the conclusion that the discipline of tourism studies will probably continue to devel...

Nickel nanoparticles (Ni NPs) are quite interesting because they exhibit high catalytic activity, high selectivity and high efficiency in fuel cells [1, 2]. However the coke-formation takes place in these NPs involving chemical reactions. For instance the CO2 reforming of methane gas in the presence of Ni NPs leads to the formation of coke containing predominantly the carbon nanotubes (CNTs) [3...
