<p>The invention relates to a reactor plate for cleaning air and/or combustion products by removal of gaseous impurities and to a method of its production consisting in mixing 100 mass units of urea with between 1 to 5 mass units of methylolurea, melting it then by exposure to up to 140 DEG C, and heating it up then to between 165 DEG C and 185 DEG C whereby at least a part of urea is transformed to cyanuric acid and to amide of allophanic acid whereupon the melted substance is poured into a mould and let to solidify. In its compact solid state, the reactor plate produced by this method comprises solidified mixture of urea, cyanuric acid , and allophanic acid. <IMAGE></p> |
