The main anthropogenic emissions (CO, CO2, NOx, SOx) produced by the processing (combustion) of wastes (coal filter cakes) were measured directly for the first time. The research considered the most widespread coal filter cakes: those of nonbaking, low-caking, coking, flame, and gas coals. These filter cakes are regarded as promising components for the technologies of coal-water slurry (CWS) an...

A USEPA, procedure, ISCLT3 (Industrial Source Complex Long-Term), was applied to model the spatial distribution of polycyclic aromatic hydrocarbons (PAHs) emitted from various sources including coal, petroleum, natural gas, and biomass into the atmosphere of Tianjin, China. Benzo[a]pyrene equivalent concentrations (BaPeq) were calculated for risk assessment. Model results were provisionally val...

The catalytic properties of non-applied nickel-sulfide catalysts in the reactions hydrogenation and hydrodesulphurization coal tar from semi-coking Shubarkul field (Republic Kazakhstan) were studied to obtain data necessary for intensification resin processing technology, increasing yield improving quality resulting needle coke. As a feedstock, was used without preliminary dehydration (water co...

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 ...

Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash am...

Mercury in coals is one of the important sources atmospheric mercury, which potentially harmful to ecological environment. Based on data 970 coal samples, concentration, spatial distribution and occurrence mercury Chinese were analyzed. The main conclusions are as follows: concentration coalfields uneven; medium high mainly distributed southwest China eastern Inner Mongolia. concentrations vari...
