Title:
AMMONIA DECOMPOSITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/153720
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an ammonia decomposition device with which the nitration of a material in a reactor in which ammonia decomposition is performed can be suppressed. An ammonia decomposition device according to the present invention comprises: a reactor that is filled with a catalyst for a decomposition reaction for decomposing ammonia, which is a raw material, into hydrogen and nitrogen; a diluent gas supply line for supplying a diluent gas so as to mix the raw material with the diluent gas having a lower ammonia concentration than the raw material before the raw material flows into the catalyst; and an ammonia combustor that combusts part of ammonia, wherein the reactor includes a catalyst housing part which houses a catalyst, the inside of the reactor is partitioned into a first chamber to which the raw material is supplied, and a second chamber provided downstream of the first chamber in the raw material flow direction, the catalyst housing part is provided so as to extend in the second chamber while communicating with each of the first chamber and the second chamber, an outflow gas line, which causes crude decomposition gas, produced from the raw material through the decomposition reaction as outflow gas, to flow out of the reactor and then causes the crude decomposition gas to flow, communicates with the second chamber on the upstream side from a communication part where the catalyst housing part communicates with the second chamber, and combustion gas from the ammonia combustor is supplied to the second chamber.
