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 ...

Abstract. The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concrete ...

It is an energyefficient process to produce a highenergy biocoal that burns clean and takes a few hours to produce [2,7,8]. Hydrothermal carbonization (HTC) is a thermochemical process that has received increasing attention. It accepts highmoisture biomass, which does not require an additional drying process prior to feeding, as raw ...

Biofuels are playing an increasingly important role since they are an attractive alternative to fossil fuels, access to which has been limited. Moreover, they can help the European Union countries meet their climate and energy objectives. There is a growing interest in the production of biofuels from the organic fraction of municipal solid wastes as secondgeneration biofuels. Such a solution ...

I. INTRODUCTION Bio coal is a form of fuel produced by drying chopped wood over a fire. Biomass Briquetting is the process of converting low bulk density biomass into high density and energy concentrated fuel briquettes. Biomass Briquetting machines are of various sizes which converts biomass into solid fuels.

Pyrolysis is a wellestablished thermochemical process that involves the thermal breakdown of biomass into various fuel components such as biochar, biooil and pyrolysis gas (A. V. Bridgwater, 2011). Biochar is a carbonaceous solid fuel which is considered an economical substitute for coal (Budarin et al., 2013; Cheng et al., 2020; Sakhiya et ...

Commonly, the torrefied product is termed biocoal or green coal and biochar when used as fuel and soil amendment. Based on the mode of operation, the torrefaction process can be practically classified into dry, wet and steam modes (Barskov et al. 2019). In dry torrefaction, biomaterial feedstock can be torrefied in nonoxidative; for example ...

The average modified combustion efficiencies increased, and burning rates were about 20% faster. The combustion of biocoal briquettes can reduce greenhouse gases like 38% CO 2 and 45% CH 4 but also hazardous air pollutants like 52% CO, 45% NO, and 29% PM effectively in comparison with the bituminous briquettes.

Biocoal with quality comparable to that of fossil coal can be produced by high temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low biocoal yield at high pyrolysis temperatures. This trade off suffers the economic feasibility of bio coal production.

The use of pretreated biomass (biocoal) as a part of the raw material blend for cokemaking could be one possible way of reducing the fossil CO2 emissions linked to the BF process. The advantage of replacing part of the fossil coal with biocoal is that the biomass regeneration time is comparatively short [4] and the effects on global warming
