Anaerobic digestion

This laboratory focuses on both basic and applied research, using biomass (including biowaste) to produce biowaste, and the research of the subsequent processes, such as biogas purification. We do modelling and evaluation of the processes of anaerobic transformation of biomass into biogas and digestate, which may both be used in energy production. We provide basic analytical service for biogas stations and we also evaluate biogas technologies. We test methane production from non-traditional substrate. We also investigate the biomass aerobic degradation process, i.e. composting. New bioreactors, especially lower capacity ones, are being developed.

Waste and fuel analysis

Our laboratory provides service for the analysis of both traditional and non-traditional fuels, different types of combustion residues and certain flue gas parameters. The laboratory is equipped for measuring thermal and technical parameters necessary to determine fuel and energy potential of different materials. We are also able to investigate physical and chemical properties of the products of combustion and pyrolysis as well as the chemical composition of other materials.

Heterogeneous photocatalysis

The laboratory of heterogeneous photocatalysis is equipped to investigate the processes of waste gas purification with the use of photocatalytic methods. Gas mixture analysis is also done. The laboratory investigates photocatalyst efficiency in photocatalytic reduction of carbon dioxide (both liquid and gas phase), photocatalytic decomposition of nitrous oxide, photocatalytic cleavage of water in the presence of methanol and degradation of MTBE from water. We also investigate photocatalytic reaction kinetics and advanced oxidation processes for waste gas purification. The laboratory is equipped with batch photocatalytic reactors with different geometries for gas and liquid phase reactions, a flow photoreactor for gas phase decomposition reactions, a gas chromatograph (BID), a photo electrochemical spectrometer, a Kelvin probe and a pilot plant unit for investigating advanced oxidation processes. The laboratory also offers testing of powder photocatalysts for reactions in gas and liquid phases, of thin films for reactions in gas and liquid phases, as well as testing of photocatalytically active materials for gas phase reactions according to ČSN ISO 22197.

Nanostructured materials

The laboratory of nanostructure materials does research in the area of preparation and optimization of the preparation of different types of nanostructure materials such as metal oxides or carbon materials, in different macroscopic forms, especially for photocatalytic and catalytic decomposition of organic pollutants in the environment and photocatalytic reduction of greenhouse gases. Nanostructure powder, thin layers or monoliths are prepared not only with the use of conventional methods, but new unconventional preparation and processing methods are also developed and optimized, e.g. using supercritical and subcritical fluids. Preparation processes and their optimization are investigated on the basic research level, focusing on the influence of individual preparation or processing steps or of the feedstock/chemical precursor on the physicochemical properties of the prepared material and, consequently, on photocatalytic or catalytic efficiency. Our laboratory also uses microwave pyrolysis to prepare carbon sorbents, which are then characterised with the use of physisorption. We focus on inter-disciplinary research, using knowledge and information from material engineering, inorganic chemistry, physical chemistry, solid state physics, photochemistry, organic technology, as well as environmental and chemical engineering.

Air protection

The laboratory of air protection is equipped for research in the area of waste gas treatment processes using catalytic and adsorption based methods. The laboratory has equipment for gaseous sample collection, i.e. a system of passive dosing of gaseous samples, including an automated sampler cleaning system. The laboratory also provides service for gaseous mixture analysis. The laboratory does research and characterisation of gas phase heterogeneous catalysts for heterogeneous reactions, applied in the purification of waste gases from stationary sources both in industrial companies and in the laboratory. It also investigates adsorption and desorption process balance and kinetics. We offer testing of industrial catalysts, research of kinetics of catalytic reactions, modelling of reaction mechanisms, chemical engineering calculations, simulation and design of chemical reactors, determination of adsorption capacities of gases and vapours, and other research tasks, based on the customer's requirements.

Reduction and plasma processes

As its name suggests, the laboratory of reduction processes focuses on waste material treatment with the use of thermal processes in a reducing environment. The laboratory has two sections.
The first section is focused on waste biomass processing, in the order to come up with products with a higher added value, i.e. using the torrefication process to produce "super pellets", using pyrolysis to produce "bio coal" or the production of carbon activated sorbents by carbonization. Biomass is processed both in a batch laboratory scale and on a continuous pilot plant. Naturally, these solid products are also analysed, including the resulting gases and fluids.
The second section focuses on waste polymer material processing done with the use of catalytic pyrolysis. This is also called chemical recycling and its principle is to recover monomers (or similar chemical substances) from polymers, and then re-use this chemical substance to produce this polymer again. The part of the polymeric materials which is impossible to process by chemical recycling as well as other types of waste, e.g. products of organic processing is reformed to hydrogen, using commercially available catalysts, as well as our own ones.

Waste incineration

This laboratory focuses on research in the area of oxidation processes in thermal treatment of waste. The laboratory is equipped with a thermal waste incinerator with an hourly capacity of 30kg of waste. The equipment is completed with a flue gas cleansing system, including both continuous and discontinuous emission monitoring of raw and treated gas. The configuration of the devices allows a wide range of scientific experiments. The research infrastructure makes it possible to perform experiments aimed at observing environmental parameters and energy aspects of the waste incineration process. Another part of our research activities is focused on the investigation of solid combustion residue, its properties and evaluation of how this residue may be used

Water

The laboratory of water does basic and applied research in water treatment, including analytical evaluation of surface and waste water. The main areas of research in water treatment are adsorption processes, photocatalytic decomposition, membrane processes, application of microwave fields and bioremediation processes. Research is done on laboratory apparatuses, using both model solutions and real water samples. Materials such as sorbents or catalysts, which are used here, are customised, based on what substances are to be removed (especially medicines and pesticides). We also provide solutions for industries. As for the analytical area, our laboratory is equipped to evaluate metals, ions, organic pollutants and biologically active substances. In this case, their mutual interaction and their influence on organisms present in water (especially bacteria and plants) are also monitored.
