Selective catalytic oxidation technology for NOx emission reduction in gasification power plants

Gasitication research at VTT Energy is mainly directed towards pressurized fluidized bed gasification and to the most critical technical questions of the so-called simplified IGCC process. Another important application is the atmospheric pressure gasification for small-scale energy production and for co-combustion in large utility boilers. The development of advanced gas-cleaning technology is a key question in these applications. Studies of selective oxidation technology have been funded by the Ministry of Trade and Industry and subsequently by Tekes through the national reseach programme, LIEKKI and the gasification programme PROGAS. Partial funding has been received also from the companies, Imatran Voima and Foster Wheeler Energia. The reseach work will be continued by an international consortium consisting of VTT Energy, Sydkraft (Sweden), Foster Wheeler Energia, Åbo Akademi University and European Gas Turbines Ltd (England). The work is part of the Joule programme funded by the European Commission and it will be co-ordinated by VTT Energy.
