“…Also, due to the intensive decomposition of organic matter, a decrease in the volatile matter occurs. We have previously established that the heat of combustion of hydrocarbon raw materials is associated with its quality [12][13][14]. As part of this study, we compared the obtained properties of charcoal with the results of other authors (Table 2).…”

The aim of this work was to determine the temperature and pressure on the quality of charcoal, obtained in the renewable energy pyrolysis of coniferous residues. Charcoal yield is found to be steadily reduced with increasing pyrolysis temperature. It was found the pyrolysis temperature increasing up to 700 °C, the pressure decreasing up to 0.1 MPa and the yield of charcoal decreasing up to ~34.5%. It is proved that the renewable energy pyrolysis temperature increasing up to 700 °C at a constant pressure level (0.1 MPa), as well as the pressure increasing up to 2 MPa at a constant temperature (550 °C) leads to an increase in FCd and HHV. The generalization of the obtained experimental studies makes it possible to optimize the renewable energy pyrolysis of coniferous residues in industrial conditions.

Use of Hydrogen–Rich Gas in Blast Furnace Ironmaking of V–bearing Titanomagnetite: Mass and Energy Balance Calculations

The iron and steel industry is a major CO2 emitter and an important subject for the implementation of carbon emission reduction goals and tasks. Due to the complex ore composition and low iron grade, vanadium−bearing titanomagnetite smelting in a blast furnace consumes more coke and emits more carbon than in an ordinary blast furnace. Injecting hydrogen−rich gas into blast furnace can not only partially replace coke, but also reduce the carbon emission. Based on the whole furnace and zonal energy and mass balance of blast furnace, the operation window of the blast furnace smelting vanadium−bearing titanomagnetite is established in this study on the premise that the thermal state of the blast furnace is basically unchanged (raceway adiabatic flame temperature and top gas temperature). The effects of different injection amounts of hydrogen−rich gases (shale gas, coke oven gas, and hydrogen) on raceway adiabatic flame temperature and top gas temperature, and the influence of blast temperature and preheating temperature of hydrogen−rich gases on operation window are calculated and analyzed. This study provides a certain theoretical reference for the follow−up practice of hydrogen−rich smelting of vanadium−bearing titanomagnetite in blast furnace.

Recent developments on the removal of zinc from electric arc furnace dust by using microwave heating

Electric arc furnace dust (EAFD) is a hazardous by-product of steel production. As global steel output increases, substantial amounts of EAFD are produced, which causes significant environmental issues. EAFD contains amounts of Fe and Zn, which could be reused as raw materials in the steelmaking process. However, zinc oxides can be reduced and vaporized during this process, forming zinc vapor that contaminates equipment surfaces and causes damage. Consequently, various pyrometallurgical methods have been proposed for zinc removal from EAFD. Due to the extensive usage of carbonaceous materials, these methods contribute to significant CO 2 , raising concerns about greenhouse gas emissions.Microwave heating offers an efficient, energy-saving, and environmentally friendly alternative to pyrometallurgical approaches. EAFD can generate heat under microwave irradiation without carbon addition, which means the CO 2 emissions can be reduced by replacing the reductant in the microwave heating process. Furthermore, microwaves enhance zinc removal reactions to a certain extent, resulting in higher efficiency. Thus, employing microwave heating for EAFD processing has significant potential for future development. This paper reviews recent research on using microwave heating for zinc removal from EAFD, focusing on the heating behavior of EAFD in microwaves and the mechanisms of zinc removal. This review will be crucial for researchers working on processing EAFD using microwave heating and could help guide the development of more sustainable and efficient methods.
