Thermally robust and chemically inert Ag@SiO2 nanoprobes are employed to provide the surface enhanced Raman scattering (SERS) effect for an in situ/operando study of the early stage of carbon deposition on nickel-based solid oxide fuel cell (SOFC) anodes. The enhanced sensitivity to carbon enables the detection of different stages of coking, offering insights into intrinsic coking tolerance of ...

Coking wastewater from the process of coking, coal gas purification and the coking products refine, whose ingredients are complicated and inconstant, is hard to meet the standard of reclaimed water used for industrial water by secondary treatment. In view of this situation, the advanced treatment technique of coking wastewater was desired. The innovatory flocculation treatment was used to regen...

The carbonization of coal to produce metallurgical coke is an alternative route for the feedstock recycling of plastic wastes of different structures and origins. Individual plastics or mixed plastics of domestic origin can be incorporated into typical coking blends as secondary raw materials. The effects of the composition of the plastic wastes on the thermoplastic properties of coal, coking p...

A laboratory-scale anaerobic sequencing batch reactor (ASBR) was used to pretreat coking wastewater. Inoculated anaerobic granular biomass was acclimated for 225 d to the coking wastewater, and then the biochemical methane potential (BMP) of the coking wastewater in the acclimated granular biomass was measured. At the same time, some fundamental technological factors, such as the filling time a...

Arsenic contamination on the surface of buildings and facilities at a coking plant and associated health risk were studied. A total of 94 wipe samples from 56 buildings and facilities were collected, and As concentrations were found to range from 0.01 to 23.90 μg/100 cm(2). 20.2% of the samples exceeded the As level calculated to present health risk: 4.02 μg/100 cm(2). Arsenic mean concentratio...

Plastic wastes, lube oils and coal-tar are evaluated, individually and combined, as additives to coal blends for the production of blast-furnace coke. The effects of adding 2 wt% of potential additives or their mixtures (50:50 w/w) on the coking capacity of coal, the pressure generated during the coking process and the coke quality parameters were evaluated. Using a combination of polyolefin wa...

Article history: Received 21 October 2014 Revised 28 October 2014 Accepted 29 October 2014 Available online 23 January 2015 In this study, ultraviolet (UV) and vacuum ultraviolet (VUV) photolysis were investigated for the pre-treatment and post-treatment of coking wastewater. First, 6-fold diluted raw coking wastewater was irradiated by UV and VUV. It was found that 15.9%–35.4% total organic ca...

The coking process is considered to be a potential source of unintentionally produced persistent organic pollutants (UP-POPs). However, intensive studies on the emission of UP-POPs from the coking industry are still very scarce. Emission of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (dl-PCBs), hexachlorobenzene (HxCBz), and pentachlorobenzen...

In this study, ultraviolet (UV) and vacuum ultraviolet (VUV) photolysis were investigated for the pre-treatment and post-treatment of coking wastewater. First, 6-fold diluted raw coking wastewater was irradiated by UV and VUV. It was found that 15.9%-35.4% total organic carbon (TOC) was removed after 24 hr irradiation. The irradiated effluent could be degraded by the acclimated activated sludge...

More than 80% of ammonia (NH₃) in the steel manufacturing process wastewater is contributed from the coking wastewater, which is usually treated by biological processes. However, the NH₃ in the coking wastewater is typically too high for biological treatment due to its inhibitory concentration. Therefore, a two-stage process including a hollow fiber membrane contactor (HFMC) and a modified memb...
