The project will be divided into two strong related parts: Taiwanese, National Taiwan University (NTU) and Polish, Institute for Chemical Processing of Coal (IChPW). During the NTU part of the project, a catalyst of TiO2/PdO (powder and anchored on solid base form) will be prepared and tested in laboratory-scale photo-reactors. Optimal process parameters like light intensity, flow rate and Pd content will be determined. Noteworthy, a “small photo-reactor” that will be used in the project, was designed by J. Lasek and J.C.S. Wu during his (J. Lasek) post-doc project work. This reactor was successfully used in the research of NOx photo-SCR and photo-epoxidation. Next, the prepared catalysts during the NTU stage of the project will be applied into a bigger flow photo-reactor that will be designed and constructed during the second part of the project realised in IChPW, Poland. It is assumed that the photo-reactor flow rate will be of 80-200 l/h (STP) and the process will be carried out under UV-light irradiation. Flue gas for the photo-reactor will be taken from combustion chambers, available in IChPW. The reactor will be designed for possible maximal utilization of light-exposing area. It means BFB reactor (3 kg/h of coal) and turbulence combustion chamber for gaseous, liquid and pulverised fuels (150 kWth). Only part of the flue gas will be introduced into photo-reactor. Thus, the reactor will be mobile but also integrated with the mentioned combustion chambers. The main goal of the project will be to obtain the highest possible de-NOx efficiency using photo-SCR in real-conditions flue gas. The process will be tested using different kind of flue gases from real-scale combustion chambers.一氧化氮脫硝光觸媒燃燒尾氣太陽光能NODeNOxphotocatalysisflue gassolar energy
