Presentation on Mineral Engineering Conference – MEC2023 – Wisła, Poland

Posted on  

On June 14-16, the Mineral Engineering Conference 2023 (MEC2023) took place in Wisła. We were very pleased to take part in this international conference and deliver a presentation entitled Bio-coke as a reductant for the ferroalloy smelting process. The conference is a forum for the exchange of knowledge, experience and integration of specialists from science and industry, representatives of the mining industry, scientists and specialists working in the field of research on the properties and use of mineral resources, as well as representatives of research units, industry companies and mining authorities.

Next fruitful project meeting in Częstochowa

Posted on  

At the end of March, the fourth project meeting was held as part of the BioCoke4FAI project – Bio-coke for ferroalloys industry production. The meeting was attended by representatives of the project partners, researchers from the SINTEF institute, engineers and technologists from the Norwegian company producing ferroalloys ERAMET and Koksownia Częstochowa Nowa, as well as employees of the Institute of Energy and Fuel Processing Technology (ITPE). This time the organizer and host of the meeting was Koksownia Częstochowa Nowa sp. z o.o. (KCN). The meeting was divided into three parts. In the first substantive part, the participants presented the current results of the project, including the results of research on the impact of the addition of various types of bio-components (including charcoal and waste biomass from food production) on the structural and quality parameters of bio-coke produced on a large-laboratory and pilot scale . The Norwegian partners presented the results of the evaluation of the parameters of bio-coke produced at ITPE within Work Package 2 in terms of its use in electric arc furnaces and ecological aspects of its use. At this stage of the work, it was concluded that bio-coke obtained on the basis of coal-biomass blends meets the requirements for carbon reductantts, and its suitability should be verified during pilot furnace tests that will take place in June and August this year at SINTEF. After discussing substantive and organizational matters, the participants went on a technological visit to the production facilities of the KCN Coking Plant – the department of coke production, by-product plant and the laboratories. On the next day, all participants had the opportunity to see the technological infrastructure of the pilot coke oven with a movable wall in the Liberty Steel Coking Plant in Ostrava. With the use of the aforementioned pilot oven, pilot tests of bio-coke production are carried out. Liberty Steel coking plant is a subcontractor in the Work Package implemented by KCN. The bio-coke produced in the pilot oven will be used for the aforementioned ferroalloy smelting tests in the pilot furnace at SINTEF. We would like to thank all participants for their participation in the meeting, interesting presentations and fruitful discussions.

Workshop – BIOCARBON – a green alternative to reduce the carbon footprint of FeMn alloy production

Together with the PREMA project, we cordially invite you to participate in the Workshop on: BIOCARBON – a green alternative to reduce the carbon footprint of FeMn alloy production. The workshop will take place on January 11-12, 2023.

The topics of the workshop include issues related to reducing carbon dioxide emissions in the industry producing ferroalloys through the use of renewable raw materials – biocarbon.

If you are a representative of the industry, science, research and development sector related to the discussed issue or you are simply interested in this topic, we cordially invite you to participate in the workshop.

Bio-coke – a chance for the Polish cokemaking industry? – discussion panel

At the XXX jubilee scientific and technical conference KOKSOWNICTWO 2022, a thematic discussion panel was held entitled: Bio-coke – a chance for the Polish cokemaking industry?. The panel was led by an employee of the Institute of Fuel and Energy Technology (ITPE), Dr. Michał Rejdak. Research on the production of bio-coke, i.e. a hybrid reducer produced on the basis of coal blends with the addition of biomass substances, has been carried out in the world for over a dozen years, but in the last few years, due to the fight against global warming and the desire to minimize greenhouse gas emissions, they have gained considerable momentum. The idea of ​​bio-coke is based on the replacement of part of the elemental carbon of fossil origin, the source of which is coking coal, with elemental carbon from renewable sources – biomass. Due to the assimilation of carbon dioxide during the photosynthesis process, biomass is considered a zero-emission resource, therefore the introduction of biomass-based carbon should contribute to the reduction of CO2 emissions from the processes of coke (bio-coke) utilization. The practical implementation of the above-mentioned idea consists in the production of bio-coke in functioning coke oven batteries, using for this purpose coal blends with properly prepared biomass raw materials – raw or thermally processed biomass (torrefaction, charcoal, etc.).

The aim of the panel was to familiarize the participants with the current state of knowledge and technology on issues related to the production of bio-coke, to present our experience in the field resulting from the BioCoke4FAI project implementation and to discuss the possibility of implementing this technology in the practice of domestic cokemaing, which is currently the European leader in the production and export of high-quality coke. The panel met with great interest of the conference participants – representatives of both industry and the scientific community. There was a lively discussion about the wide implementation potential of the technology in question. Particular emphasis in the discussion was put on the elements related to the economic and ecological aspects of obtaining biomass raw materials, the process of thermally processed biomass production, including the phenomena and mechanisms occurring in its course. It was concluded that the industrial implementation of bio-coke production technology requires the acquisition of full knowledge and optimization of factors shaping its quality parameters, taking into account the requirements of industrial processes in which it will be used.

Presentation on the 2nd International Conference EFE 2022 (Energy Fuels Environment)

On September 20-23 at AGH University of Science and Technology in Kraków (Cracow), the 2nd International Conference EFE 2022 – Energy Fuels Environment took place. At the conference, we presented a paper entitled “The influence of charcoal addition to coking blend on bio-coke quality parameters.

Study visit at SINTEF

Posted on  

From 1 to 3 June, IChPW employees Michał Rejdak and Małgorzata Wojtaszek – Kalaitzidi took a study visit as part of the BioCoke4FAI project. The study visit took place at the Norwegian research Institute SINTEF in Trondheim, which is also the research partner of the project. The visit was supervised by Michał Książek from SINTEF. As part of the visit, IChPW employees participated in technological research of bio-coke produced at the Institute. The research included parameters important for the production of manganese ferroalloys, such as electrical resistance, reactivity to CO / CO2 gas (SINTEF method), studies of the microstructure of biocokes by EPMA (electron microscopy) and slag reactivity.

BioCoke4FAI – 3rd Project Meeting

Presentation on the 37th International Cokemaking Conference

On November 10 and 11, the 37th International Cokemaking Conference was held. The conference took place in Ostrava in the Czech Republic, and was attended by over 100 representatives of several dozen companies related to the cokemaking industry and research companies from various European countries. At the conference, a poster was presented: The influence of charcoal addition to coking blend on quality parameters of produced bio-coke. The poster shows the current results of the assessment of the charcoal addition (to the coking blend) on the quality parameters of produced bio-cokes. The tests were carried out for the conditions of the gravity charged and stamp charged coke oven batteries. The obtained results are promising and met with the interest of the conference participants.
