A group of Danish researchers works with an invention regarding the selective catalytic reduction (SCR) of nitrogen oxides (NOX) from flue gases comprising alkali salts. Alkali-containing flue gases are produced when combusting biomass and combined biomass/fossil fuels in power plants as well as from waste incineration units. The client is looking for co-operation with producing companies interested in licence agreement, technical co-operation or alternatively taking over the patent.
