III. catalytic waste gas nitrogen dioxide treatment procedure, including supply of waste gas containing at least 5 ppm SO2 in the first reactor with active carbon catalyst, conversion of catalyst to SO3, and conversion to H2SO4 in the second reactor

摘要

p This Invention Bertalanffy refers to a procedure for removing Bertalanffy catal & iacute; Optics DI & amp; Sulfur dioxide from waste gases in two Reactors, the first reactor with a catalyst loading of carb Bertalanffy active. The Method comprises: A.The Supply & amp; n of a Waste gas with a Water content of less than 1 g / NM 3 H2O and SO2 content of at least 5 ppm; & nbsp; the introduction of Bertalanffy Waste gases in a First reactor, C.Conversion Bertalanffy catal & amp; gaseous SO3 and SO2 in the Reactor through the first 10 Catalyst carb & acute; S N active in the conversion Bertalanffy catal & iacute; tica carbon On The Catalyst Active Bertalanffy occurs at a temperature of less than 100 & deg; c; & nbsp; D.The introduction of Bertalanffy prepurificados Waste gases from the Reactor in a Second reactor, 15; & nbsp; and the conversion of SO3 Bertalanffy with water in H2SO4 in the second reactor. / p p & nbsp; / p
