1. Fremgangsmåde til testning af en honeycomb-formet katalysator til fjernelse af NOx til anvendelse i et apparat til fjernelse af NOx-røggas, hvor katalysatoren har gasledninger til fremføring af en afgangsgas fra et indløb til et udløb i hver ledning og til udførelse af fjernelse af NOx på sidevæggene af ledningen, kendetegnet ved, at fremgangsmåden omfatter at tilvejebringe et første teststykke, som er parti af katalysatoren med en længde, der fuldstændigt dækker en turbulensstrømzone, i hvilken en gas, der skal behandles, og som er blevet indført i gasledningerne gennem indløbet af katalysatoren til fjernelse af NOx, danner en turbulent strøm, og endvidere dækker i det mindste et parti af en laminarstrømzone, i hvilken den turbulente strøm ensrettes til dannelse af en laminar strøm; at udføre en første NOx-fjernelsestest for det tilvejebragte første teststykke; efterfølgende at udføre en anden NOx-fjernelsestest for et andet teststykke, som er opnået ved udskæring af et katalysatorparti med en længde, der dækker tur-bulensstrømzonen; og på basis af testresultaterne at vurdere den katalytiske præstation af turbulens-strømzonen og af laminarstrømzonen, hvorved den katalytiske præstation af katalysatoren til fjernelse af NOx vurderes.
2. Fremgangsmåde ifølge krav 1, hvor turbulensstrømzonen har en længde Lb (mm), som er repræsenteret ved følgende ligning: Lb = 77,56 a hvor ”a” er en konstant, der falder inden for området 3 til 6.
3. Fremgangsmåde ifølge krav 1 eller 2, hvor den første eller den anden test til fjernelse af NOx udføres, medens en modelgas med en sammensætning, der simulerer gassen, som behandles i et faktisk apparat til fjernelse af NOx, fremføres med en gasindstrømningshastighed, der er ækvivalent med den, der anvendes i et faktisk apparat til fjernelse af NOx, hvorved katalysatorpræstationen bestemmes.
4. Fremgangsmåde ifølge krav 1 eller 2, hvor den første eller den anden test til fjernelse af NOx udføres, medens en modelgas med en sammensætning, der simulerer gassen, som behandles i et faktisk apparat til fjernelse af NOx, fremføres med en strømningshastighed, der afviger fra den, der anvendes i et faktisk apparat til fjernelse af NOx, hvorved katalysatorpræstationen bestemmes under hensyntagen til forholdet mellem gasindstrømningshastighed og reageret NOx.
5. Fremgangsmåde ifølge et hvilket som helst af krav 1 til 4, hvor den første eller den anden test til fjernelse af NOx omfatter bestemmelse af NOx-koncentrationer på indløbssiden og udløbssiden af respektive teststykker; bestemmelse af ΝΗΙ3-koncentrationer på indløbssiden og udløbssiden af respektive teststykker; og bestemmelse af procentvis fjernelse af NOx på basis af et indløb-molforhold (dvs. indløb-NH3/indløb-NOx).
6. Fremgangsmåde ifølge krav 5, hvor den procentvise fjernelse af NOx bestemmes på basis af IMF^-koncentrationer.
