Formation and Elimination of Emissions of PCDD/F at Combustion of Waste Plastic Materials
Veselý, Václav ; Hanika, Jiří ; Lederer, J. ; Nečesaný, F. ; Kukačka, J.
The effect of individual components of waste plastic materials (forming the alternative fuel) was studied. The attention was paid to formation of emissions of polychlorinated dioxins and furanes. Process arrangements were proposed that led to their reduction. Combustion tests were executed on a model unit with thermal output of 50 kW. It was proved that the dominant effect on content of PCDD/F in flue gases had the presence of PET and PVC. To reduce emissions of persistent organic compounds it was possible to use the second stage high-temperature combustion in the layer of CaO or dolomite. But by this arrangement the emissions of Cl2 or HCl were not reduced.

CFD Simulation of Hydrogen Production by Biomass Partial Oxidation
Tukač, V. ; Hanika, Jiří ; Veselý, Václav ; Lederer, J. ; Kovač, D. ; Nečesaný, F.
Nowadays hydrogen demand caused by deep fuel refining and the other sustainable processes leads to utilization of new raw materials. Simultaneously, extensive biodiesel production creates great amount of biomass wastes transcendent over feeding potential of farm animals. One of potentially useful process of hydrogen production from renewable natural sources seems to be partial oxidation (POX) and gasification of biomass material like rape meal from rape oil production and/or distillery slop originated from bioethanol. The goal of this work was to develop simulation models of pilot POX reactor working with mixture of fuel oil and biomass.

Petelyse-PET Recycling
Veselý, Václav ; Kouřil, M.
Report sumarised up the results of project petelyse-chemical recycling of PET boltes. The analytical method was valided for watching of a technologie. The data from pilot plant was ground of design and material and energy balance and development of aparates. This report was base for feasibility study of process chemical PET botles recycling.

Petelyza-Chemical PET Recycling
Veselý, Václav
This report treat of selection of clients on chemical recycling process PETELYSE for recycling PET botles. Investment study summarised results of research anad development of technology true to scale 100 kg PET per hour. The technologie is protected by 2 patents. The marketing of produkts is importanr for the investments in recyclation technology. This study treat not of produkt selling and source of PET material
