PLANT FOR THE PRODUCTION OF HYDROGEN AND ALUMINUM TRIHYDRATE Russian patent published in 2023 - IPC C01B3/08 C01F7/42 C01F7/14 B01J7/02 

FIELD: gas generating plant.

SUBSTANCE: plant for the production of hydrogen and aluminum trihydrate Al(OH)₃ consists of a hydrogen chemical reactor (HCR), a water jacket for cooling the HCR and a recuperator for suspended reaction products. HCR is made in the form of a vertical sealed vessel, the cavity of which is divided into three horizontal sections, including a hydrogen gas generator, a liquid reactant displacer and a receiver with a hydraulic seal for accumulating and filtering hydrogen from foreign impurities. The gas generator cavity is connected to the receiver cavity through a gas outlet pipe and to the displacer cavity through an overflow pipe. To enter chemical reagents, the HCR is equipped with a loading basket, an inlet/outlet pipe of a chemically active liquid into the liquid reagent displacer cavity, a hydrogen outlet fitting from the receiver cavity, and a valve for the outlet of suspended reaction products. This valve is connected at the outlet to the first inlet of the heat exchanger, the second inlet of which is connected to the outlet pipe of hot water from the HCR cooling water jacket. The recuperator for liquid recuperation products is connected to the inlet/outlet pipe of the HCR chemically active liquid, and for solid reaction products containing aluminum trihydrate, with the pipe for their output to the storage tank.

EFFECT: obtaining hydrogen for heating and power supply systems of low-rise buildings remote from main gas and power supply lines, while simultaneously producing aluminum trihydrate suitable for preparing high-quality construction mixtures.
