The research conducted in CCTW is possible both in the laboratory, large laboratory scale up to PDU which increases the commercial potential of the technologies researched in CCTW.
The Department of Energy Saving and Air Protection is a part of the Clean Coal Technology Centre (CCTC) created within the structure of the Central Mining Institute – one of the largest R&D institutes in Poland. The research infrastructure of the Department, covering both the laboratory scale and pilot scale installations, make it applicable in a wide range of research fields, in particularly related but not limited to:
• coal processing and utilization, with a focus on clean coal technologies
• characterization and utilization of materials in energy, environmental engineering and chemical synthesis sectors
• waste valorization
• carbon dioxide capture and utilization
• modelling of multi-dimensional data sets
We are open to cooperation with industrial and academic environment taking into consideration the specific needs of our potential partners.
The High-Pressure Thermogravimetric Analyzer installation coupled with mass spectrometer allows the experimental verification of processes of thermochemical conversion of solid fuels including fossil fuels, biomass and wastes. The gaseous media applied include air, oxygen, carbon dioxide and nitrogen. It operates under isothermal and dynamic conditions. The maximum operating temperature is 1350ºC at the atmospheric pressure and 1100ºC at the maximum operating pressure of 4 MPa.
The Differential Scanning Calorimeter (DSC) determines the temperature and heat flow associated with material transitions as a function of time and temperature. It also provides quantitative and qualitative data on endothermic (heat absorption) and exothermic (heat evolution) processes of materials during physical transitions that are caused by phase changes, melting, oxidation, and other heat-related changes. The operating temperature is from -90 to 550°C.
The Thermogravimetric Analyzer provides simultaneous measurement of weight change (TGA) and true differential heat flow (DSC) on the same sample. The temperature range is from ambient to 1500°C, and the heating rate is from 0.1 to 100°C/min. The applicable gaseous media include nitrogen, argon, helium, air, oxygen and carbon dioxide.
The Autosorb iQ analyzer with extended low pressure capability is applicable in the specific surface area, pore volume and pore size distribution measurements. The pore size range measured is from 0.35 to 500 nm, the specific surface from 0.0005 m2/g and the total pore volume from 0.0001 cm3/g.

The pilot-scale moving bed reactor is designed to perform large scale tests on gasification of solid fuels at temperatures up to 1200ºC and under pressure up to 3 MPa. It gives the possibility to test the thermochemical conversion processes at larger scale, thus reducing possible scale-effects. The gaseous media like air, oxygen, and CO2 may be applied.
