Abstract:
1. A device for producing ammonia from solid urea pellets stored in a reservoir, comprising: a pellet dispensing device; a pellet accelerator; a pellet shooting channel; an ammonia reactor having a chamber or a zone for enclosing urea pellets, a pellet deflector disposed on an end of a free shooting path, a urea evaporation device, and a hydrolytic catalytic converter, wherein the urea pellets are removable from the reservoir in a regulated amount by means of the pellet dispensing device and are transported to the pellet accelerator, wherein the pellets are accelerated to a high speed mechanically and internally via the pellet accelerator, wherein the pellets are shot into the ammonia reactor from the pellet accelerator via the pellet shooting channel, wherein on the end of the shooting path, the pellets are broken down into a plurality of pellet pieces by the deflector and are immediately thereafter convertible into a gas mixture containing ammonia and isocyanic acid by means of the urea evaporation device, and wherein together with water vapor, the gas mixture is conducted through the hydrolytic catalytic converter, whereby the isocyanic acid is converted into ammonia and carbon dioxide.
