Due to global warming, technologies reducing CO2 emissions in the metallurgical industry are being sought. One possibility is to use biocoke as a substitute for classic coke made of fossil coal. Biocoke can be produced on the basis of coal with the addition of substances of biomass origin. Blends for the production of biocoke should have appropriate cokemaking properties to ensure the ...

Therefore, it is urgent to develop a highquality coking coal production process with relatively mild parameters. Some experts have attempted to mix additives in order to produce higherquality biochar under relatively low operation parameters, found that additive itself had a certain influence on the product properties [30].
