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 ...

The ecological footprint model was used in this paper to evaluate the sustainable development status of Baotou City by calculating footprint, carrying capacity and deficit/surplus 2018. results showed that: (1) In 2018, per capita 1.11506 ha, 0.8371 ha. There is 0.2780 ha deficit, which a fragile unsustainable state; (2) demand for farmland, grassland fossil energy land large, but limited; (3) ...

one of the most important methods to produce sponge iron is coal based reduction of iron ore. direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. volatile materials in coal play an important role in the reduction of iron oxides. in this study, noncoking coal with high volatile materials from iran and c...

Optimizing coal blending is important for high-quality development of coking industries, among which deep understanding relationships between characteristics and coke quality critical. This work selected four typical coals from Shanxi Province in China to investigate influences their structures properties on quality. Although these samples belong coals, the mechanical strength thermal correspon...

The Xishan coalfield is an important coking coal-producing area in China. No. 8 and 9 coals of the Taiyuan formation were sampled tested from nine mines center north coalfield, coal’s quality characteristics, element occurrence enrichment sedimentary environment characteristics analyzed to provide a foundation for clean efficient coal utilization identification associated resources. results obt...

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 ...
