Ammonia gas generator useful e.g. for producing ammonia from ammonia precursor solution, and in gas engines, comprises catalyst unit comprising catalyst and mixing chamber, injection device having nozzle, and outlet for formed ammonia gas

摘要

Ammonia gas generator (100) comprises: a catalyst unit (70) comprising a catalyst (60) for decomposing and/or hydrolyzing ammonia precursors into ammonia, and a mixing chamber (51) arranged upstream of the catalyst; an injection device (40) for introducing the ammonia precursor solution into the mixing chamber, comprising a nozzle exhibiting a theoretical spray angle (alpha ) of 10-90[deg] ; and (iii) an outlet for formed ammonia gas. The catalyst has a catalyst volume. The mixing chamber has a mixing chamber volume. The distance of the nozzle opening to the end face of the catalyst is 15-2000 mm.
