Zusammenfassung:	To provide a selective reduction catalyst system that makes effective use of LNH3, etc., carried on board a ship as fuel or cargo, and allows the use of an existing urea water supply system facility for an engine, etc., of the ship, and to provide a reductant spray method.SOLUTION: According to one aspect of the present invention, a selective reduction catalyst system and a reductant spray method are provided. The selective reduction catalyst system comprises a mixing part and a spray part. The mixing part mixes ammonia with urea water stored in an existing tank of a ship. The spray part is configured to spray a synthetic reductant produced by the mixing.SELECTED DRAWING: Figure 1 【課題】燃料または貨物として船舶に搭載されるＬＮＨ３等を有効利用しつつ、当該船舶のエンジン等に既設の尿素水供給系の設備を流用できる選択式還元触媒システムおよび還元剤噴霧方法を提供することを目的とする。【解決手段】本発明の一態様によれば、選択式還元触媒システムおよび還元剤噴霧方法が提供される。この選択式還元触媒システムは混合部と、噴霧部とを備える。混合部は、船舶の既設タンクに貯蔵された尿素水に、アンモニアを混合する。噴霧部は、混合により生成された合成還元剤を噴霧するよう構成される。【選択図】図１
