Coal Geology and Geochemistry
This panel will contain among others following issues: the chemical and mineralogical characteristic of the coal. The impact of both organic and inorganic matter on the use of carbon in various applications. The correlation between coal seams and the content of basic and trace elements. Geochemical interactions in coal seams. Geology of coal seams. Problems in coal mines. As well as geochemistry of enhanced coal bed methane recovery and CO2 storage in coal seams ant others.
Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from run-of-mine (ROM) coal to a product that meets the customer’s requirements or can be used for different purposes such as power generation. This and other aspects related with coal gasification will be discussed in this panel.
This session will be related to coal combustion processes. Particularly scope of the panel includes: processes and technologies for coal and solid fuel combustion (basic and applied research), combustion of renewable fuels and its co-firing with coal. Moreover, the thematic scope of the panel contain also issues related to: process modeling, technical and economic analysis, as well as materials and control and measurement systems.
Coal Pyrolysis and Gasification
The panel concerns all aspects related to gasification and pyrolysis of solid fuels, especially coal. The subject of the panel covers: basic research on the gasification and pyrolysis process, including process kinetic as well as behaviour and transformation of a mineral matter. Furthermore the following issues are included in the topic: underground coal gasification (UCG), industrial applications, economics and environmental issues, synthesis gas cleanup and conversion, new gasification and pyrolysis technologies and its application, poligeneration systems, modeling and system analysis.
Gaseous and Liquid Chemicals
This topic will include each aspects of gaseous and liquid chemicals that are used for coal processing in order to increase effciency and reduction of pollution (for example addition of bromine salts to reduction of mercury emission). As well as characteristic of gaseous and liquids by-products obtained in coal processing. An example would be Fischer-Tropsch Synthesis in which olefins, paraffins, alcohols, aldehydes and ketones are obtained.
Low Rank Coals
Low-rank coal is defined as consisting of a gross caloric value (e.g. heating value) of less than 24 MJ/kg (moist, ash-free basis) and mean vitrinite reflectance as less
than 0.6%. Low-rank coals (LRCs), i.e., brown, lignite, and subbituminous coals, represent nearly half of the estimated coal resources in the world. In many of the developing nations,
LRCs are the primary source of low cost energy. This topic is about low rank coal processing as well as problems associated with the use of this raw material i.e. spontaneous ignition.
Coke, Coal Tar, Coal Combustion Products (CCP)
Coke is a fuel that is obtained from the calcination or dry distillation of mineral coal. It is composed of carbon and has a high calorific value, but it is highly polluting. It is used as fuel in the blast furnaces of steel foundries. Coal tar is a brown or black liquid of extremely high viscosity. It is among the by-products when coal is carbonized to make coke or gasified to make coal gas. Coal tars are complex and variable mixtures of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds. This topic is about the production of new coal materials based on coke and coal tar or improvement of existing processing techniques, e.g. reduction of toxic gases from coke combustion. Besides in this panel each aspects of Coal Combustion Product (CCP) will be discussed i.e. problem with the storage of them, potential application (building industry, source of silica in synthesis of porous solid sorbents,
High Efficiency Low Emission (HELE) Technologies
Deploying high efficiency, low emission (HELE) coal-fired power plants is a key first step along a pathway to near-zero emissions from coal with carbon capture, use and storage. HELE technologies are commercially available now and, if deployed, can reduce greenhouse gas emissions from the entire power sector by around 20%.
Improvements in the efficiency of coal-fired power plants can be achieved with technologies including:
Carbon Dioxide Capture, Utilisation and Storage
The panel concerns all aspects related to CO2 emission during solid fuels processing. Panel thematic will concerns among others issues related to CO2 capture (pre and post combustion), CO₂ sequestration and CO2 utilization processes.
Biofuels are considered renewable energy sources and are an environmentally friendly alternative to oil and other fossil fuels. Among them can be distinguished solid biofuels such as wood, which can be used directly in the combustion process, and also liquid biofuels such as ethanol which can be used, for example, in transport. This panel concerns, among others, feedstock for biomass production, their properties and the use of by-products obtained from the production of biofuels.
The purpose of a fuel cell is to produce an electrical current that can be directed outside the cell to do work, such as powering an electric motor. It is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy. Depending on the required materials alkali, molten carbonate (MCFC), phosphoric acid (PAFC), proton exchange membrane (PEM), solid oxide (SOFC) fuel cells can be distinguished. This topic covers all types of fuel cells, as well as research into their parts such as anode, cathode or electrolyte and also the production of clean energy by them.
Coal combustion is associated with the production of Coal Combustion Products (CCPs) such as fly ash, bottom ash, boiler slag and flue gas desulfurization residue. These by-products pose a risk to the environment by the content of toxical trace elements and metalloids. Moreover, gases (SOx, NOx, CO2, CO) produced in coal processing or wastewaters (FGD wastewater) are also dangerous. This topic is dedicated to gas and wastewater treatment methods as well as the possibilities of CCPs using.
Circular Economy / 0 Waste Emission
Circular economy and resource efficiency have recently gained enormous attention as solutions to global resourcescarcity. The zero waste emission and circular economy goal is to minimize the amount of waste placed in landfills or incinerated. This topic concerns a new dimension of a diversified progress which is to make it possible through centring of activities on an efficient use of secondary raw materials and minimising the use of resources, to realise growth in the economy which would not add to the impact exerted on the natural environment.
