摘要： A fluid reactor device, in particular a fluid purification device, is provided. The fluid reactor device includes a heat-transfer bed comprising a first opening, a second opening and heat storage material arranged between the first opening and the second opening. The heat storage material is configured to heat fluid flowing through the heat storage material such that the fluid heats up and reacts while flowing through the heat storage material. At least one structural or thermal property of at least one of the heat-transfer bed and the heat storage material varies along at least one spatial direction.
