A vessel for use in hydrothermal synthesis, comprises: a vessel body to be heated from outside; an inner tubular vessel which is placed within the vessel body with a tubular gap being formed therebetween, the inner tubular vessel having an inner surface which is formed of a precious metal such as silver, gold or platinum, and having a cover with a first small hole therein; and a buffer compartment for covering the first small hole, the buffer compartment having one wall which is defined by the cover and having the other wall with a second small hole therein.

Vessel for use in hydrothermal synthesis

A heat exchanger using two hydrogen storage alloys, including: a tubular housing member disposed in a horizontal position; a vertical partition plate extending axially within the housing member for partitioning the inside space of the housing member into two, first and second reaction zones in which the first and second alloys are contained, respectively, to form an upper space above each alloy; first and second heat-exchange tubes disposed in the first and second reaction zones, respectively, and arranged so that first and second fluids may be passed therethrough for indirect heat exchange with the first and second alloys, respectively; openings provided in the vertical partition plate at least at positions so that the upper space in the first and second reaction zones are in fluid communication with each other; and a plurality of vertically extending gas passages provided in each of the first and second reaction zones, and each being in fluid communication with the upper space, whereby hydrogen gas released from one of the first and second alloys can efficiently diffuse in the other alloy.
