An ammonia gas generator for producing ammonia from a solution of an ammonia precursor substance, comprising a catalyst unit that comprises a catalyst for the decomposition and/or hydrolysis of ammonia precursor substances into ammonia and a mixing chamber provided upstream of the catalyst; an injection device for injecting the solution of the ammonia precursor substance into the mixing chamber; at least one inlet for the carrier gas; and an outlet for the formed ammonia gas, said ammonia gas generator also comprising a perforated disc.

Ammonia gas generator, method for producing ammonia and use of the same for reducing nitrogen oxides in exhaust gases

The present invention relates to a method for generating ammonia from an ammonia precursor substance and to the use thereof for reducing nitrogen oxides in exhaust from industrial facilities, from combustion engines, from gas engines, from diesel engines or from petrol engines.

Method for the production of ammonia from an ammonia precursor substance in order to reduce nitrogen oxides in exhaust gases

Ammonia gas generator for producing ammonia from a solution of an ammonia precursor substance comprising a catalyst unit, which comprises a catalyst for the decomposition and/or hydrolysis of ammonia precursor substances into ammonia and a mixing chamber arranged upstream of the catalyst, an injection device for introducing the solution of the ammonia precursor substance into the mixing chamber, and an outlet for the ammonia gas formed, wherein the injection device comprises a nozzle which produces droplets having a Sauter mean diameter Dof 26 to 100 &#x3bc;m.

Ammonia gas generator and use of the same for reducing nitrogen oxides in exhaust gases

The present invention relates to an ammonia gas generator for generating ammonia from an ammonia precursor substance and to the use thereof for reducing nitrogen oxides in exhaust, in particular from industrial facilities, from combustion engines, from gas engines, from diesel engines or from petrol engines.

Ammonia gas generator for producing ammonia in order to reduce nitrogen oxides in exhaust gases

The invention relates to an ammonia gas generator for producing ammonia from an ammonia precursor substance as well as the use thereof in exhaust after treatment systems. The invention further relates to a method for producing ammonia gas to reduce nitrogen oxides in exhaust gases, in particular combustion gases from internal combustion engines such as diesel engines.
