摘要： An exhaust gas control apparatus includes a control device (8) that controls a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst (7). The control device (6) obtains an ammonia adsorption amount distribution through the NOx reduction catalyst (7), and when an ammonia adsorption amount in a predetermined part on an exhaust gas flow direction downstream side equals or exceeds a predetermined threshold, the control device (8) controls the urea addition valve (6) to stop the urea supply or reduce the amount of urea supply. The urea addition valve (6) is controlled basis on an adsorption amount distribution obtained from a model on which the catalyst is divided into a plurality of cells such that an ammonia adsorption amount in a first cell (71) positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell (72) positioned downstream of the first cell (71) reaches a predetermined target value that is smaller than the threshold.

摘要： A hydrogen generator provided with a cracker which cracks a compound containing hydrogen atoms and nitrogen atoms to generate hydrogen, a compound feeder which feeds the compound to the cracker, and an oxygen feeder which feeds oxygen to the cracker. The cracker includes catalyst particles which promote the cracking of the compound and catalyst particles which promote the oxidation of the compound. The cracker is fed with the compound and oxygen, causes the compound to oxidize to generate heat of oxidation, and uses the generated heat of oxidation to crack the compound.
